TRICYCLIC PYRAZOLE DERIVATIVES < RTI ID = 0.0 >
[2] At least 400 enzymes have been identified as protein kinases. These enzymes catalyze the phosphorylation of the target protein substrate. Phosphorylation is typically the transfer of a phosphato group from ATP to a protein substrate. The specific structure of the target substrate to which the phosphite is delivered is a tyrosine, serine, or threonine residue. Because the amino acid residues are the target structure for phosphate transfer, the protein kinase enzymes are generally referred to as tyrosine kinases or serine / threonine kinases.
[3] Phosphorylation reactions at tyrosine, serine, and threonine residues and counteracting phosphatase responses are mediated by responses to various intracellular signals (typically mediated through cell receptors), regulation of cellular function, and activation and inactivation of cellular action It is associated with a number of underlying cellular effects. The chain reaction of protein kinases often participates in intercellular signaling, which is necessary for the realization of the cellular action. Owing to their omnipresence in this action, protein kinases can be found as essential parts of the plasma membrane or as cytoplasmic enzymes or can often be located in the nucleus as a component of the enzyme complex. In many instances, the protein kinase is an essential component of enzymes and structural protein complexes that determine when and where cellular action occurs within a protein complex that determines when and where cellular action occurs within the cell.
[4] Protein tyrosine kinase . Protein tyrosine kinases (PTKs) are enzymes that catalyze the phosphorylation of specific tyrosine residues in cellular proteins. The post-translational modification of the substrate protein, often the enzyme itself, serves as a molecular switch to control cell proliferation, activation or differentiation (Schlessinger and Ulrich, 1992, Neuron 9: 383-391). Abnormal or excessive PTK activity has been observed in many disease states, including benign and malignant proliferative disorders as well as diseases that result in inappropriate activation of the immune system (e.g., autoimmune disorders), allograft rejection, and graft versus host disease . In addition, epithelial cell-specific receptor PTKs, such as KDR and Tie-2, mediate angiogenesis and are therefore useful in the treatment of cancer and other inappropriate vascularization (e.g., diabetic retinopathy, choroidal neovascularization due to age- Psoriasis, arthritis, retinopathy of prematurity, infantile hemangioma).
[5] The tyrosine kinase may be a receptor-type (with extracellular, transmembrane and intracellular domains) or a non-receptor type (present within cells as a whole).
[6] Receptor tyrosine kinase (RTK) . RTKs include a large family of transmembrane receptors with diverse biological activities. Currently, at least 19 different RTK subfamilies have been identified. The receptor tyrosine kinase (RTK) family includes receptors important for growth and differentiation of various cell types (Yarden and Ullrich, Ann. Rev. Biochem. 57: 433-478, 1988; Ullrich and Schlessinger, Cell 61: 243-254, 1990). The intrinsic function of the RTK is activated upon ligand binding, which causes phosphorylation of the receptor and multiple cell substrates followed by a variety of cellular responses (Ullrich & Schlessinger, 1990, Cell 61: 203-212). Thus, receptor tyrosine kinase mediated signal transduction is typically initiated by extracellular interactions with specific growth factors (ligands), following receptor dimerization, stimulation of native protein tyrosine kinase activity, and phosphorylation. Thereby forming a complex with a variety of cytoplasmic signaling molecules that promote binding sites for intercellular signaling molecules and promote appropriate cell responses (eg, cell division, differentiation, metabolic effects, changes in the extracellular microenvironment) (Schlessinger and Ullrich, 1992, Neuron 9: 1-20).
[7] Proteins with SH2 (src homology-2) or phosphotyrosine binding (PTB) domains bind to highly-activated activated tyrosine kinases and their substrates that propagate signals into cells. Both domains recognize phosphotyrosine (Fantl et al ., 1992, Cell 69: 413-423; Songyang et al ., 1994, Mol. Cell. Biol . 14: 2777-2785; Songyang et al ., 1993, Cell 72: 767-778; and Koch et al ., 1991, Science 252: 668-678; Shoelson, Curr. Opin. Chem. Biol . (1997), 1 (2), 227-234; Cowburn, Curr. Opin. Struct. Bio . (1997), 7 (6), 835-838). Several intracellular substrate proteins that bind receptor tyrosine kinase (RTK) have been identified. These can be divided into two major groups: (1) substrates with a catalytic domain; And (2) a substrate lacking the domain but acting as an adapter and binding to a catalytically active molecule (Songyang et al ., 1993, Cell 72: 767-778). The specificity of the interaction between the receptor or protein and the SH2 or PTB domains of their substrate is determined by the amino acid residues immediately surrounding the phosphorylated tyrosine residue. For example, differences in binding affinities between SH2 domains and amino acid sequences surrounding phosphotyrosine residues on a particular receptor are correlated with differences observed in their substrate phosphorylation profile (Songyang et al ., 1993, Cell 72: 767-778). Observations suggest that the function of each receptor tyrosine kinase was determined not only by its expression pattern and ligand availability, but also by the arrangement of the downstream signaling pathway, which is activated by the timing and duration of the particular receptors as well as by the stimuli. Thus, phosphorylation provides an important regulatory step in determining the selectivity of the signaling pathway supplemented by the specific growth factor receptor as well as the differentiation factor receptor.
[8] Several receptor tyrosine kinases and their associated growth factors have been suggested to play a role in angiogenesis, although some may indirectly promote angiogenesis (see Mustonen and Alitalo, J. Cell Biol . 129: 895- 898, 1995). One such receptor tyrosine kinase known as " fetal liver kinase 1 " (FLK-1) is a member of the type III subclass of RTK. Another notation for human FLK-1 is the " kinase insert domain-containing receptor " (KDR) (Terman et al ., Oncogene 6: 1677-83, 1991). Another alternative notation for FLK-1 / KDR is " Vascular Endothelial Growth Factor Receptor 2 " (VEGFR-2) because it binds with high affinity VEGF. The murine version of FLK-1 / VEGFR-2 is also referred to as NYK (Oelrichs et al , Oncogene 8 (1): 11-15, 1993). DNA encoding the mouse, rat and human FLK-1 has been isolated and this nucleotide and encoded amino acid sequence has been reported (Matthews et al ., Proc. Natl. Acad. Sci . USA, 88: 9026-30, 1991; Terman et al, 1991, supra; Terman et al, B iochem Biophys Res Comm 187:...... 1579-86, 1992; Sarzani et al, supra; and Millauer et al, Cell 72:.. 835 -846, 1993). A number of studies, such as those reported in Millauer et al., Have shown that VEGF and FLK-1 / KDR / VEGFR-2 are important for the proliferation of vascular endothelial cells and the formation and production of blood vessels, respectively called angiogenesis and angiogenesis, Lt; / RTI > is a ligand-acceptor pair that acts as a ligand.
[9] Another type III subclass RTK, designated "fms-like tyrosine kinase-1" (Flt-1), is associated with FLK-1 / KDR (DeVries et al. Science 255; 989-991, 1992; Shibuya et al., Oncogene 5: 519-524, 1990). Another notation for Flt-1 is " Vascular Endothelial Growth Factor Receptor 1 " (VEGFR-1). To date, members of the FLK-1 / KDR / VEGFR-2 and Flt-1 / VEGER-1 subfamilies have been found to be mainly expressed on endothelial cells. These subclass members are characteristically stimulated by members of the vascular endothelial growth factor (VEGF) family of ligands (Klagsburn and D'Amore, Cytokine & Growth Factor Reviews 7: 259-270, 1996). Vascular endothelial growth factor (VEGF) binds to Flt-1 with a higher affinity for FLK-1 / KDR and is fragmented into vascular endothelial cells (Terman et al., 1992, supra ; Mustonen et al. supra ; DeVries et al., supra ). Flt-1 is thought to be essential for endothelial cell organization during angiogenesis. Flt-1 expression is associated with angiogenesis during early angiogenesis and wound healing in mouse embryos (Mustonen and Alitalo, supra ). Expression of Flt-1 in adult tissues, such as the renal glomeruli, suggests an additional function on the receptor that is not associated with cell growth (Mustonen and Alitalo, supra ).
[10] As described above, recent evidence suggests that VEGF plays a role in stimulating both normal angiogenesis and pathological angiogenesis (Jakeman et al ., Endocrinology 133: 848-859, 1993; Kolch et al ., Breast Cancer Research and Treatment 36: 139-155, 1995; Ferrara et al ., Endocrine Reviews 18 (1); 4-25, 1997; Ferrara et al., Regulation of Angiogenesis (ed. LD Goldberg and EM Rosen), 209-232, 1997]. In addition, VEGF has been associated with the control and enhancement of vascular permeability (Connolly, et al ., J. Biol. Chem . 264: 20017-20024, 1989; Brown et al ., Regulation of Angiogenesis (ed. LD Goldberg and EM Rosen), 233-269, 1997].
[11] Other forms of VEGF due to another splicing of mRNA have been reported, including four species described by Ferrara et al . ( J. Cell, Biochem . 47: 211-218, 1991). Both secreted and predominantly cell-associated species of VEGF have been identified by Ferrara et al. (Supra), and the protein has been found to be present in the form of a disulfide linked dimer.
[12] Several related isomorphs of VEGF have recently been identified. However, their role in normal physiological and pathological function has not yet been elucidated. In addition, members of the VEGF family are often co-expressed with VEGF in a number of tissues, and can generally form heterodimers with VEGF. These properties seem to alter receptor specificity and the biological effects of heterodimers and make it difficult to explain their specific function as further illustrated below (see Korpelainen and Alitalo, Curr. Opin. Cell Biol , 159-164, 1998, and references cited within the document).
[13] Placental growth factor (PlGF) has an amino acid sequence that exhibits significant homology with the VEGF sequence (Park et al., J. Biol. Chem . 269: 25646-54, 1994; Maglione et al. -31, 1993). Like VEGF, another species of PlGF results from another splicing of mRNA, and the protein is present in dimeric form (Park et al., Supra ). PlGF-1 and PlGF-2 bind to Flt-1 with high affinity and also PlGF-2 binds well to neurofilin-1 (Migdal et al., J. Biol. Chem . 273 (35): 22272 -22278), but not FLK-1 / KDR (Park et al., Supra ). PlGF has been reported to affect both vascular permeability and mitogenic effects on endothelial cells when VEGF is present at low concentrations (intentionally due to heterodimer formation) (Park et al., Supra ).
[14] VEGF-B is produced as two homologues (167 and 185 residues), such as binding to Flt-1 / VEGFR-1. This can serve to regulate extracellular matrix degradation, cell adhesion and migration through regulation of the expression and activity of the urokinase-type plasminogen activator and plasminogen activator inhibitor 1 (Pepper et al, Proc. Natl. Acad. Sci. USA (1998), 95 (20): 11709-11714].
[15] VEGF-C was originally cloned as a ligand for VEGFR-3 / Flt-4, which is predominantly expressed by lymphatic endothelial cells. In its fully processed form, VEGF-C may bind to KDR / VEGFR-2 and stimulate endothelial cell proliferation and migration in vitro and angiogenesis in vivo models (Lymboussaki et al, Am. J. Pathol . (1998), 153 (2): 395-403; Witzenbichler et al, Am. J. Pathol . (1998), 153 (2), 381-394). Transgenic overexpression of VEGF-C results in proliferation and expansion of the lymphatic vessel only, without affecting the blood vessels. Unlike VEGF, expression of VEGF-C is not induced by hypoxia (Ristimaki et al, J. Biol. Chem . (1998), 273 (14), 8413-8418).
[16] The most recently discovered VEGF-D is structurally very similar to VEGF-C. VEGF-D has been reported to bind and activate at least two VEGFRs, VEGFR-3 / Flt-4 and KDR / VEGFR-2. It is originally cloned as c-fos capable of inducing mitotic material for fibroblasts and is predominantly expressed in mesoderm cells of lung and skin (Achen et al, Proc. Natl. Acad. Sci. U.S.A. (1998), 95 (2), 548-553 and references in the document).
[17] It has been postulated that VEGF-C and VEGF-D, when injected into dermal tissues, induce an increase in vascular permeability in vivo in Miles assay (see PCT / US97 / 14696; WO98 / 07832, Witzenbichler et al ., supra ). The physiological role and importance of the ligand in controlling the blood vessel, permeability and endothelial cell response in the tissues in which the ligand is expressed are unclear.
[18] VEGF and VEGFR Based on the novel discovery of the animal and the precedent for ligand and receptor heterodimerization, the action of the VEGF-phase animal is to determine the hemodynamics of the VEGF ligand heterodimer and / or the heterodimerization of the receptor, 0.0 > VEGFR < / RTI > (Witzenbichler et al., Supra). Recent reports also suggest that receptors other than neurotrophilin-1 (see Migdal et al, supra ) or VEGFR-3 / Flt-4 (Witzenbichler et al., Supra) or KDR / VEGFR- Suggest that it may be related to the induction of atherosclerosis (Stacker, SA, Vitali, A., Domagala, T., Nice, E., and Wilks, AF, "Angiogenesis and Cancer" Assoc. Cancer Res., Jan. 1998, Orlando, FL; Williams, Diabetelogia 40: S118-120 (1997)]. To date, no direct evidence has been found for the essential role of KDR in VEGF-mediated blood vessels and permeability.
[19] Nonreceptor tyrosine kinase . Non-receptor tyrosine kinases represent a collection of extracellular and membrane-bound cellular enzymes. Currently, more than 24 individual non-receptor tyrosine kinases have been identified, including 11 subfamilies (Src, Frk, Btk, Csk, Abl, Zap70, Fes / Fps, Fak, Jak, Ack and LIMK). Currently, the Src subfamily of non-receptor tyrosine kinases is composed of the largest number of PTKs and includes Src, Yes, Fyn, Lyn, Lck, Blk, Hck, Fgr and Yrk. The Src subfamily of enzymes is involved in tumorigenesis. A more detailed description of nonreceptor tyrosine kinases is provided in Bolen, 1993, Oncogene 8: 2025-2031, which is incorporated herein by reference.
[20] A variety of tyrosine kinases, which are RTK or non-receptor tyrosine kinases, psoriasis; ≪ / RTI > and other hyperproliferative diseases or hyperimmune responses.
[21] Development of compounds that modulate PTKs . In view of the presumed importance of PTKs to the control and regulation of cell proliferation, diseases and disorders associated with abnormal cell proliferation, mutant ligands (US Patent No. 4,966,849), soluble receptors and antibodies (WO94 / 10202; 1993, Nature 362: 841-844), RNA ligands (Jellinek, et al., Biochemistry 33: 10450-56; 1992, J. Cellular Phys., 152: 272-402, 1992. Exp. Cell Res. 199: 56-62; Wright et al., 1993, Mol. Bio. Cell 4: 358A; Kinsella, et al. 448-57) and tyrosine kinase inhibitors (WO 94/03427, WO 91/15495, WO 94/14808, US Patent No. 5,330,922; Mariani, et al., 1994, Proc. Am. Assoc. Cancer Res. 35: 2268) have been attempted to identify receptor and non-receptor tyrosine kinases.
[22] More recently, attempts have been made to identify small molecules that act as tyrosine kinase inhibitors. For example, bis-monocyclic, bicyclic or heterocyclic aryl compounds (PCT WO 92/20642) and vinylene-azaindole derivatives (PCT WO 94/14808) are generally described as tyrosine kinase inhibitors. (US Patent Application No. 5,302,606), some quinazoline derivatives (EP Patent Application No. 0 566 266 A1; Expert Opin. Ther. Paat. (1998), 8 (4): 475-478) (PCT WO 94/03427), tricyclic polyhydroxy compounds (PCT WO 92/21660) and benzylphosphonic acid compounds (PCT WO 91/15495) as tyrosine kinase inhibitors for use in the treatment of cancer Is described as a compound to be used. Anilinocinoline (PCT WO 97/34876) and quinazoline derivative compounds (PCT WO 97/22596; PCT WO 97/42187) are described as inhibitors of angiogenesis and vascular permeability.
[23] Attempts have also been made to identify small molecules that act as serine / threonine kinase inhibitors. For example, bis (indolylmaleimide) compounds have been described as inhibiting certain PKC serine / threonine kinase isoforms that are associated with vascular permeability that has been dysfunctional in VEGF-related diseases.
[24] In order to regulate and regulate abnormal or inappropriate cell proliferation, differentiation, or metabolism, it is desirable to identify effective small compounds that specifically inhibit signal transduction by modulating the activity of receptor and non-receptor tyrosine and serine / threonine kinases. In particular, angiogenesis methods; It is beneficial to identify methods and compounds that specifically inhibit the function of tyrosine kinases that are essential for the formation of edema, ascites, exudates, exudates, and extracellular efflux and matrix deposition as well as associated disorders of blood vessels and permeability.

[509] The present invention further includes the use of these compounds in pharmaceutical compositions containing a pharmaceutically effective amount of the compound and a pharmaceutically acceptable carrier or excipient. These pharmaceutical compositions can be administered to an individual to slow or stop the angiogenic process in diseases promoted by angiogenesis or to treat other conditions associated with edema, effusion, exudate, or vaginal hyperplasia have.
[1] The present invention relates to certain 3-aryl or 3-heteroarylpyrazoles with 4,5 (3,4) -bicyclic ring fusions which are inhibitors of protein kinases, in particular tyrosine kinases and serine / threonine kinases, , A pharmaceutical composition containing the pyrazole, and a method for producing the pyrazole.
[510] The compounds of the present invention have anti-angiogenic properties. Such anti-angiogenic properties are due to inhibition of protein tyrosine kinases which are necessary for the partial or complete angiogenic process. For these reasons, these compounds are useful in the treatment of arthritis, atherosclerosis, psoriasis, hemangiomas, myocardial angiogenesis, coronary and cerebral palsy, ischemic limb angiogenesis, wound healing, peptic ulcer Helicobacter related diseases, fractures, cat scratch fever ), Rubeosis, angiogenesis glaucoma, and retinopathy associated with diabetic retinopathy, retinopathy such as retinopathy of prematurity, retinopathy of premature keratosis, and the like. In addition, some of these compounds have been shown to be useful in the treatment of solid tumors, malignant ascites, hematopoietic carcinomas, and thyroid hyperplasia, particularly Grave's disease, cysts (e. G., Polycystic ovary syndrome (Stein-Leventhal syndrome and ovarian hypervascularisation characterized by hyperglycemia and syndrome), since this disease requires the proliferation of vascular cells for proliferation and / or metastasis.
[511] Some of these compounds may also be used in the treatment of inflammation of the brain or lungs due to burns, chronic lung disease, stroke, polyps, anaphylaxis, chronic and allergic inflammation, ovarian hyperstimulation syndrome, brain tumor associated brain edema, elevation, trauma or hypoxemia, And corneal hemorrhage, ascites, vascular and permeability, effusion, exudation, protein efflux, or edema may be used as active agents for other diseases in which the disease is a symptom. Such compounds would also be useful for treating diseases in which protein efflux causes precipitation of fibrin and extracellular matrices to promote matrix proliferation (e.g., fibrosis, sclerosis, carpal tunnel syndrome).
[512] VEGF is unique in that it is the only angiogenic growth factor known to contribute to blood vessel and permeability and edema formation. Indeed, the vasculature, permeability and edema associated with the expression or administration of many other growth factors appear to be mediated by VEGF production. Inflammatory cytokines stimulate VEGF production. Since hypoxia leads to significant upregulation of VEGF in many tissues, conditions involving infarction, obstruction, ischemia, anemia, or circulatory disturbance typically result in a VEGF / VPF mediated response. Changes in blood vessels and permeability, associated edema, changes in vascular endothelial exchange and polymer leakage are often accompanied by diapedesis, which can lead to excessive matrix accumulation, abnormal substrate proliferation, fibrosis, and the like. Therefore, VEGF mediated and permeability can contribute significantly to diseases with these pathologic features.
[513] It is believed that the diseases listed above are mediated to a significant extent by protein tyrosine kinase activity, including KDR / VEGFR-2 and / or Flt-1 / VEGFR-1 tyrosine kinase. By inhibiting the activity of these tyrosine kinases, the progression of the diseases listed above is inhibited because of the severity of angiogenic or vascular and transmissible components of the disease state. The action of the compounds of the present invention minimizes side effects that occur when less selective tyrosine kinases are used, due to their selectivity for specific tyrosine kinases.
[514] The compounds of the present invention have inhibitory activity against protein kinases. That is, these compounds regulate signal transduction by protein kinases. The compounds of the present invention inhibit protein kinases of serine / threonine and tyrosine kinase classes. Specifically, these compounds selectively inhibit the activity of KDR / FLK-1 / VEGFR-2 tyrosine kinase. Certain compounds of the invention also inhibit the activity of additional tyrosine kinases such as Flt-1 / VEGFR-1, Src-subtype kinases such as Lck, Src, fyn, yes, In addition, some compounds of the present invention significantly inhibit serine / threonine kinases such as CDK, which play an important role in cell cycle progression. The potency and specificity of the generic compounds of the invention for a particular protein kinase will often depend upon the nature, number and arrangement of substituents (i.e., R ₁ , R ₂ , R ₃ , R ₄ , R ₅ and R ₆ ) Lt; / RTI > In addition, metabolites of certain compounds may also have significant protein kinase inhibitory activity.
[515] The compounds of the present invention, when administered to an individual in need of such a compound, inhibit blood vessel and permeability and edema formation in these individuals. These compounds are believed to act by inhibiting the activity of KDR tyrosine kinase in relation to blood vessel and permeability and edema formation processes. The KDR tyrosine kinase may also be referred to as FLK-1 tyrosine kinase, NYK tyrosine kinase, or VEGFR-2 tyrosine kinase. KDR tyrosine kinase binds to KDR tyrosine kinase where vascular endothelial growth factor (VEGF) or other activating ligand (e.g., VEGF-C, VEGF-D or HIV Tat protein) is present on the surface of vascular endothelial cells Activated. After activation of this KDR tyrosine kinase, hyperpermeability of the blood vessels occurs and body fluids migrate from the bloodstream to the interstitial space through the blood vessel walls, forming a swelling site. Extravasation often involves these reactions. Similarly, excessive blood vessels and permeability can cause polymer leakage and precipitation by interrupting normal molecular exchange across the endothelium of important tissues and organs (e.g., lungs and kidneys). Following this acute response to KDR stimulation, which is believed to promote subsequent angiogenic responses, subsequent KDR tyrosine kinase stimulation results in vascular endothelial cell proliferation and chemotaxis and formation of new blood vessels. By inhibiting the enzyme activity of KDR tyrosine kinase (inhibiting the phosphorylation function of the enzyme) by inhibiting KDR tyrosine kinase activity, or by blocking the binding of the activating ligand to the KDR tyrosine kinase receptor, by inhibiting receptor dimerization and phosphorylation, Or by other mechanisms that interfere with downstream signaling (D. Mukhopedhay et al. Cancer Res 58: 1278-1284 (1998) and references to the literature), over permeability as well as related efflux, subsequent edema formation and matrix precipitation and angiogenic responses can be suppressed or minimized.
[516] One of the preferred compounds of the present invention has the property of inhibiting KDR tyrosine kinase activity without significantly inhibiting Flt-1 tyrosine kinase activity (Flt-1 tyrosine kinase also referred to as VEGFR-1 tyrosine kinase). Both KDR tyrosine kinase and Flt-1 tyrosine kinase are activated by binding of VEGF to the KDR tyrosine kinase receptor and the Flt-1 tyrosine kinase receptor, respectively. Since Flt-1 tyrosine kinase activity can mediate important events in endothelial maintenance and vascular function, inhibition of such enzymatic activity can lead to toxic effects or side effects. At the very least, this inhibition is useless and worthless to an individual, as it is unnecessary to block angiogenic responses, induce blood vessels and permeability, and block the formation of edema. Certain preferred compounds of the invention inhibit the activity of one VEGF-receptor tyrosine kinase (KDR) that is activated by an activating ligand, but inhibit other receptor tyrosine kinases, such as Flt-1, which may also be activated by certain activating ligands It is unusual because it does not. Thus, preferred compounds of the invention are selective for tyrosine kinase inhibitory activity.
[517] The compounds of the present invention are also useful for the treatment of ulcers, i.e. bacterial, fungal, ulcerative ulcers and ulcerative colitis.
[518] The compounds of the present invention may also be used in the treatment of viral infections such as herpes simplex, herpes zoster, AIDS, Kaposi sarcoma, protozoan infections and endocytosis, endometriosis, ovarian hyperstimulation syndrome, systemic lupus, sarcoidosis, Anemia, Lyme disease, pemphigoid, Paget's disease, oligohydrologic syndrome, Osler-Weber-Ranges disease, chronic inflammation, chronic obstructive pulmonary disease, asthma, rheumatoid arthritis, osteoarthritis, and edema after trauma, It is also useful for the treatment of diseases in which angiogenesis, edema, or substrate precipitation occurs.
[519] The compounds of the present invention can be used in the treatment of ocular and corneal edema, ocular angiogenesis, scleritis, radial keratectomy, uveitis, vitreous hemorrhage, myopia, optic pits, chronic retinal detachment, rheumatic complication, conjunctivitis, Stargardt's disease, as well as eye diseases such as retinopathy and corneal degeneration.
[520] The compounds of the present invention are also useful for the treatment of cardiovascular diseases such as atherosclerosis, restenosis, vascular occlusion, and carotid obesity.
[521] The compounds of the present invention are useful for the treatment and prophylaxis of a variety of diseases including solid tumors, hematopoietic malignancies including sarcoma (especially, wing sarcoma and osteosarcoma), retinoblastoma, rhabdomyosarcoma, neuroblastoma, leukemia and lymphoma, It is useful for the treatment of indications related to carcinoma.
[522] The compounds of the present invention are also useful in the treatment of diabetic diseases such as glaucoma, diabetic retinopathy, and capillary blood vessels.
[523] It is believed that the disorders listed above are mediated to a significant extent by protein tyrosine kinase activity, including VEGF receptors (e. G., KDR and Flt-1). By inhibiting the activity of these tyrosine kinases, the progression of the diseases listed above is inhibited because the angiogenic components of the disease state are severely reduced. The action of the compounds of the present invention minimizes side effects that occur when less selective tyrosine kinases are used, due to their selectivity for specific tyrosine kinases.

[541] Pharmaceutical preparations that can be used orally include push-fit capsules made of gelatin, as well as soft, sealed capsules made of gelatin and plasticizers such as glycerol or sorbitol. The push-fit capsules may contain the active ingredient in admixture with a filler such as lactose, a binder such as starch, and / or a lubricant such as talc, magnesium stearate, and optionally a stabilizer. In soft capsules, the active compound may be dissolved or suspended in suitable liquids such as fatty oils, liquid paraffin, or liquid polyethylene glycols. In addition, a stabilization system can be added. All formulations for oral administration should be in dosages suitable for such administration.
[542] For buccal administration, the compositions may be in the form of tablets or lozenges formulated in conventional manner.
[543] In the case of inhalation administration, the compounds used according to the invention may be formulated in the form of an aerosol spray or nebuliser in pressurized pack, in the presence of a suitable propellant, for example dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoro Ethane, carbon dioxide, or other suitable gas. In the case of a pressurized aerosol, the dosage unit may be determined by providing a valve for administering the metered amount. Capsules and cartridges of, for example, gelatin for use in an inhaler or insufflator may be formulated to contain a powder mix of the compound and a suitable powder base such as lactose or starch.
[544] The compounds may be formulated for parenteral administration by injection, e. G. By large dose or continuous infusion. The injectable formulations may be presented in unit dosage form, for example in ampoules or in multi-dose containers, with a preservative added. The compositions may take such forms as suspensions, solutions or emulsions in oily or aqueous vehicles, and may contain adjuvants such as suspending, stabilizing and / or dispersing agents.
[545] Pharmaceutical compositions for parenteral administration include aqueous solutions of the active compound in water-soluble form. Additionally, suspensions of the active compounds may be prepared as suitable oily injection suspensions. Suitable lipophilic solvents or vehicles include fatty oils such as sesame oil, or synthetic fatty acid esters such as ethyl oleate or triglycerides, or liposomes. The aqueous injection suspension may contain a substance that increases the viscosity of the suspension, for example, sodium carboxycellulose, sorbitol, or dextran. Optionally, the suspension may contain a suitable stabilizing agent or a medicament which increases the solubility of the compound to produce a highly concentrated solution.
[546] Alternatively, the active ingredient may be in powder form for reconstitution into a liquid form using a suitable vehicle, e. G., Sterile, non-pyrogen-free water prior to use.
[547] The compounds may be formulated into rectal compositions containing conventional suppository bases such as suppositories or retention enemas, for example cocoa butter or other glycerides.
[548] In addition to the formulations described above, the compounds may also be formulated as a depot preparation. Such long acting formulations may be administered by implantation (e. G., Subcutaneously or intramuscularly or by intramuscular injection). Thus, for example, the compounds may be formulated or sparingly soluble with suitable polymeric or hydrophobic materials (for example as an emulsion in an acceptable oil) or ion exchange resins and may be, for example, ≪ / RTI >
[549] An example of a pharmaceutical carrier for the hydrophobic compounds of the present invention is a cosovent system comprising benzyl alcohol, a nonpolar surfactant, an organic polymer that is miscible with water, and a water phase. The co-solvent system may be a VPD co-solvent system. VPD is a solution of 3 w / v% benzyl alcohol, 8 w / v% nonpolar surfactant polysorbate 80, and 65 w / v% polyethylene glycol 300, prepared in volume in absolute ethanol. The VPD co-solvent system (VPD: 5W) consists of VPD diluted 1: 1 in 5% glucose in aqueous solution. These cosolvent systems dissolve hydrophobic compounds well, and themselves exhibit low toxicity when administered systemically. In essence, the proportion of the co-solvent system can vary considerably without eliminating solubility and toxicity characteristics. In addition, the nature of the cosolvent component may vary, for example, other non-toxic nonpolar surfactants may be used in place of polysorbate 80; The fraction size of the polyethylene glycol may vary; Other biocompatible polymers may be substituted for polyethylene glycols, such as polyvinylpyrrolidone; Other sugars or polysaccharides may replace glucose.
[550] Alternatively, other delivery systems for hydrophobic drug compounds may be used. Liposomes and emulsions are well known examples of delivery vehicles or carriers for hydrophobic drugs. In addition, certain organic solvents, such as dimethylsulfoxide, can be used in spite of greater toxicity. Additionally, the compound may be administered using a sustained release system, such as a semi-permeable matrix of a solid hydrophobic polymer containing the therapeutic agent. Various sustained-release materials have been established and are well known to those skilled in the art. Sustained-release capsules can release compounds over a period of several days to 100 days, depending on their chemical nature. Depending on the chemical nature and biological stability of the therapeutic agent, additional strategies for protein stabilization may be used.
[551] The pharmaceutical composition may also comprise a suitable solid or gel carrier or excipient. Examples of such carriers or excipients include, but are not limited to, calcium carbonate, calcium phosphate, various sugars, starch, cellulose derivatives, gelatin, and polymers such as polyethylene glycol.
[552] Many organic molecules of the present invention can be provided as salts with pharmaceutically compatible counterions. Pharmaceutically compatible salts can be formed with many acids including, but not limited to, hydrochloric acid, sulfuric acid, acetic acid, lactic acid, tartaric acid, malic acid, succinic acid and the like. Salts tend to be more soluble in aqueous or other protonic solvents than are the corresponding free base forms.
[553] Effective dose
[554] Pharmaceutical compositions suitable for use in the present invention include compositions wherein the active ingredient is contained in an amount effective to achieve its intended purpose. More specifically, the therapeutically effective amount refers to an amount effective to prevent or alleviate the development of existing symptoms of the subject being treated. Determination of an effective amount can be made sufficiently by the ability of those skilled in the art.
[555] For compounds used in the methods of the invention, a therapeutically effective amount can be estimated initially from cellular assays. For example, the dosage can be formulated in cell and animal models to achieve a circulating concentration range that includes the IC ₅₀ (the concentration of the test compound that achieves half the maximum inhibition rate of a given protein kinase activity) as measured in cellular assays have. In some cases it is appropriate to measure the IC ₅₀ in the presence of 3 to 5% serum albumin as this approach approaches the binding effect of the plasma protein on the compound. Moreover, the most preferred compounds for systemic administration effectively inhibit intact intracellular protein kinase signaling at levels that can be safely achieved in plasma.
[556] A therapeutically effective amount refers to that amount of a compound that improves patient symptoms. The toxicity and therapeutic efficacy of these compounds can be determined, for example, by standard pharmaceutical procedures in cell cultures or experimental animals to determine the maximum tolerated dose (MTD) and the ED ₅₀ (effective dose for 50% of the maximal response) Lt; / RTI > The dose ratio between toxic and therapeutic effects is the therapeutic index, which can be expressed as the ratio between MTD and ED ₅₀ . Compounds that exhibit a high therapeutic index are preferred. Data obtained from such cell culture assays and animal studies can be used to formulate dosage ranges for use in humans. The dosage of such compounds is preferably within the range of circulating concentrations that include the ED ₅₀ with little or no toxicity. The dosage may vary within this range depending on the dosage form employed and the route of administration employed. The exact formulation, route of administration and dosage can be chosen by the individual physician in light of the patient's condition (see, e.g., Fingl et al., 1975, " The Pharmacological Basis of Therapeutics ", Ch. 1 pl]. In the treatment of seizures, administration of an acute bolus or injection that approaches MTD may be required to obtain a rapid response.
[557] The dosage and administration interval can be adjusted individually to provide a plasma level or minimal effect concentration (MEC) of the active moiety sufficient to maintain the kinase modulating effect. The MEC will vary for each compound, but can be estimated from the in vitro data, e.g., the concentrations needed to achieve 50-90% inhibition of the protein kinase using assays described herein. The dosage required to achieve the MEC will depend on the nature of the individual and the route of administration. However, HPLC assays or in vivo assays can be used to measure plasma concentrations.
[558] Dosage intervals can also be determined using MEC values. The compound should be administered using a treatment that maintains plasma levels higher than the MEC for 10 to 90%, preferably 30 to 90%, and very preferably 50 to 90% of the time until a desired improvement of symptoms is achieved . In the case of local administration or selective absorption, effective local concentrations of such agents may not be related to plasma concentrations.
[559] The amount of composition administered will, of course, be dependent upon the subject being treated, the weight of the subject, the severity of the disease, the manner of administration and the judgment of the prescribing physician.
[560] Packaging
[561] The composition may optionally be provided in a pack or dispensing device which may contain one or more unit dosage forms containing the active ingredient. Such a pack may comprise a metal or plastic foil, such as a blister pack. Such packs or dispensing devices may be accompanied by instructions for administration. Compositions comprising a compound of the invention formulated with a suitable pharmaceutical carrier can also be prepared in a suitable container, embedded and labeled for treatment of the indicated conditions.
[562] In some formulations, it may be advantageous to use the compounds of the present invention in the form of very small sized particles, for example as obtained by fluid energy milling.
[563] In the compositions of the present invention, the active compound may optionally be combined with other suitable pharmacologically active ingredients. For example, the compounds of the present invention inhibit or prevent the production of VEGF, weaken the intracellular response to VEGF, block intracellular signaling, inhibit vascular permeability hyperactivity, reduce inflammation, Or one or more additional pharmacological agents that inhibit or prevent the formation of angiogenesis. The compounds of the present invention may be administered concurrently with, after, or prior to an additional pharmaceutical agent, whatever the route of administration is appropriate. Additional pharmacologic agents include, but are not limited to, antidepressant steroids, NSAIDS, ras inhibitors, anti-TNF agents, anti-IL1 agents, antihistamines, PAF-antagonists, COX-1 inhibitors, COX- But are not limited to, PKC inhibitors and PI3 kinase inhibitors. The compounds of the present invention and further pharmaceutical agents act additionally or synergistically. Thus, the administration of such a combination of substances that inhibit angiogenesis, vascular permeability hyperactivity, and / or inhibit the formation of edema results in a more severe adverse effect of angiogenic diseases such as angiogenesis, vascular permeability hypertrophy or edema Can be reduced. In the treatment of malignant diseases, antiproliferative or cytotoxic chemotherapy or combination with radiotherapy is expected.
[564] The invention also encompasses the use of a compound of formula (I) as a medicament.
[565] Both Src and Syk of kinases play an important role in the regulation of immune function. The Src classes now include Fyn, Lck, Fgr, Fes, Lyn, Src, Yes, Hck and Blk. Syk is currently understood to include only Zap and Syk. These two classes of kinases are involved in the alteration of proinflammatory cytokine signals and growth factors through multiple receptors. Although BTK and ITK, members of the kinase Tec family, play roles that are less important in immunology, their modulation by inhibitors can prove to be therapeutically beneficial. Kinases RIP, IRAK-1, IRAK-2, NIK, IKK-1 and IKK-2 are involved in the signal transduction pathway for important pro-inflammatory cytokines TNF and IL-1. In view of the ability to inhibit one or more of these kinases, the compounds of formula (I) may function as immunomodulators useful in the maintenance of allografts and the treatment of autoimmune diseases. Through their ability to activate inflammatory processes or T cell activation, these compounds can be used to treat such autoimmune diseases. Graft versus host for host or graft versus transplant tissue due to rejection is limited by the toxicity of currently available immunosuppressive agents and may benefit from efficacious agents with improved therapeutic indices. Gene targeting experiments have demonstrated the essential role of Src in the biology of osteoclasts, the cells responsible for aggregate absorption. Through their ability to modulate Src, compounds of formula (I) may also be useful in the treatment of osteoporosis, marble osteoporosis, Paget's disease, tumor-induced hypercalcemia and bone metastasis.
[566] Many protein kinases have been demonstrated to be protooncogenes. A truncation or mutation in the case of the Abl gene having a BCR (such as a chromosomal breakage (at the breakpoint of the ltk kinase on chromosome 5), such as translocation (Philadelphia chromosome), c-Kit or EGFR as in ) Result in the generation of poorly regulated proteins in which these kinases convert the original tumor gene into a tumor gene product. In another tumor, oncogenes are caused by autocrine or paracrine ligand / growth factor receptor interactions. Members of src kinases generally engage downstream signaling to activate oncogenes, which can be oncogenic or mutated into oncogenes. By inhibiting the protein kinase activity of these proteins, the disease process can be interrupted. The vascular recurrent stricture layer may include a process of FGF and / or PDGF-stimulated smooth muscle and endothelial cell proliferation. Inhibition of FGRr or PDFGr kinase activity may be an efficacious way to inhibit this phenomenon. Thus, the kinase activity of the normal or modified c-kit, c-met, c-fms, src-family members, EGFr, erbB2, erbB4, BCR- Ab1, PDGFr, FGFr and other receptors or cytosol tyrosine kinases Compounds of formula (I) which inhibit may be of value in the treatment of benign and tumor proliferative diseases.
[567] In many pathologies (eg, solid primary tumors and metastasis, Kaposi sarcoma, rheumatoid arthritis, blindness due to improper neovascularization, psoriasis and atherosclerosis), progression of the disease can occur during persistent angiogenesis have. Often, polypeptide growth factors produced by disease tissues or associated inflammatory cells and their corresponding endothelial cell specific receptor tyrosine kinases (e.g., KDR / VEGFR-2, Flt-1 / VEGFR-1, Tie- Tek and Tie) are essential for the stimulation, regulation, organization, differentiation of the endothelial cell growth and establishment of the new functioning vasculature required. As a result of VEGF " vascular permeability enhancing factor " activity in mediating vascular permeability hyperactivity, VEGF stimulation of VEGFR kinase is associated with tumor ascites, cerebral and pulmonary edema, pleural and pericardial effusion, delayed type hypersensitivity reaction, , And guided edema leading to glaucoma or blindness due to trauma, burns, ischemia, diabetic complications, endometriosis, adult respiratory distress syndrome (ARDS), hypertension associated with post-cardiopulmonary bypass and hypertension and inappropriate neovascularization . In addition to VEGF, recently identified VEGF-C and VEGF-D, and HIV-Tat proteins can also induce vascular permeability hyperactivity through VEGFR kinase stimulation. Tie-2 is also expressed as a special population of hematopoietic stem cells that can play a role in the proliferation, adhesion, regulation and differentiation ( Blood 89, 4317-4326 (1997) A specific agent according to formula (I) that is capable of blocking the kinase activity of endothelial cell-specific kinases would be able to inhibit disease progression related to this situation.
[568] Pharmaceutical compositions containing a compound of formula (I) or a salt thereof or a therapeutically effective amount can be used to treat disorders of benign and tumorigenic diseases and immune systems. Such diseases include autoimmune diseases such as rheumatoid arthritis, thyroiditis, type 1 diabetes, multiple sclerosis, sarcoidosis, bowel disease, myasthenia gravis and systemic lupus erythematosus; Cancer of humans such as psoriasis, organ transplant rejection (e.g., kidney rejection, graft versus host disease), benign and tumor proliferative diseases, lung, breast, stomach, bladder, colon, pancreas, ovary, prostate, Hematopoietic malignancies (leukemia and lymphoma), and diseases related to inappropriate angiogenesis, such as diabetic retinopathy, premature retinopathy, choroidal angiogenesis due to age-related macular degeneration, and infantile hemangiomas in human immunity. In addition, such inhibitors may be useful for the treatment of VEFG-mediated edema, ascites, diseases associated with diffusions, and exudates, including spot edema, cerebral edema, and ARDS.
[569] The compounds of the present invention may also be useful in the prevention of such diseases.
[570] Another aspect of the present invention relates to the use of a compound of formula (I) or a salt thereof, for the manufacture of a medicament for the treatment of disorders of vascular permeability, angiogenesis dependent disease, proliferative disease and / or immune system in a mammal, To use.
[571] The present invention also encompasses methods of treating disorders of vascular permeability, inappropriate angiogenesis, proliferative disease and / or immune system, including the administration of a compound of formula (I) to a mammal, particularly a human, in need thereof do.
[572] The in vitro potency of the compounds in inhibiting such protein kinases can be determined by the procedures detailed below.
[573] The efficacy of the compounds can be determined by the amount of inhibition of phosphorylation of the exogenous substrate by the test compound (for example, synthetic peptides (Z. Songyang et al., Nature 373: 536-539) against the control.
[574] Preparation of KDR tyrosine kinase using baculovirus system
[575] The coding sequence for the human KDR intracellular domain (aa789-1354) was generated by PCR using cDNA isolated from HUVEC cells. The poly-His ₆ sequence was also introduced at the N-terminus of this protein. This fragment was cloned into the transfection vector pVL1393 at the Xba I and Not I sites. Recombinant baculovirus (BV) was generated via co-transfection using BaculoGold Transfection reagent (PharMingen). Recombinant BV was plaque purified and assayed by Western blot. For protein production, SF-9 cells were grown in SF-900-II medium at 2x10 < 6 > / ml and infected with 0.5 plaque forming units (MOI) per cell. Cells were harvested 48 hours after infection.
[576] Purification of KDR
[577] SF-9 cell expression (His) ₆ KDR (aa789-1354) was dissolved in 50 ml of Triton X-100 lysis buffer (20 mM Tris, pH 8.0, 137 mM NaCl, 10% glycerol, 1% Triton X- PMSF, 10 [mu] g / ml aprotinin, 1 [mu] g / ml leupeptin) was added to cell pellets from 1 L cell culture.

The cell lysate was added to the NiCl ₂ chelating sepharose column in 5ml, it was equilibrated with 50mM HEPES, pH 7.5, 0.3M NaCl . KDR was eluted using the same buffer containing 0.25 M imidazole. Column fractions were analyzed using SDS-PAGE and ELISA assays to determine kinase activity (below). The purified KDR was replaced with 25 mM HEPES, pH 7.5, 25 mM NaCl, 5 mM DTT buffer and stored at -80 [deg.] C.
[578] Human Tie-2 Kinase Generation and Purification
[579] The coding sequence for the human-2 intracellular domain (aa775-1124) was generated via PCR isolated from human placenta as a template. The poly-His ₆ sequence was introduced at the N-terminus and this construct was cloned into the transfection vector pVL1939 at the Xba I and Not I sites. Recombinant BV was produced by co-transfection using Baculo Gold transfection reagent (PharMingen). Recombinant BV was plaque purified and assayed by Western blot. For protein production, SF-9 insect cells were grown in SF-900-II medium at 2x10 < 6 > / ml and infected at 0.5 MOI. Purification of the His-tagged kinase used in the screening was similar to that described for KDR.
[580] Human Flt-2 tyrosine kinase generation and purification
[581] The baculovirus expression vector pVL 1393 (Phar Mingen, Los Angeles, CA) was used. The nucleotide sequence encoding poly-His6 was located 5 'to the nucleotide region (amino acids 786-1338) encoding the entire intracellular kinase domain of human Flt-1. Nucleotide sequences encoding the kinase domain were generated by PCR using a cDNA library isolated from HUVEC cells. Histidine residues enabled the affinity purification of proteins in a manner similar to that for KDR and ZAP70. SF-9 insect cells were infected at 0.5 multiplicity and collected at 48 hours post-infection.

The nucleotide sequence encoding the amino acid M (H) 6 LVPR ₆ S was located 5 'to the region encoding all of ZAP70 (amino acids 1-619). Tucleotide sequences encoding the ZAP70 coding region were generated by PCR using a cDNA library isolated from the jurquat immortalized T-cells. Histidine residues made it possible to purify the affinity of the protein (see below). The LVPR ₆ S bridge constitutes a recognition sequence for proteolytic degradation by thrombin, enabling the removal of affinity tags from the enzyme. SF-9 insect cells were infected at 0.5 MOI and collected at 48 hours post-infection.

[590] Enzyme Linked Immunosorbent Assay for PTK (ELISA)
[591] An enzyme-linked immunosorbent assay (ELISA) was used to detect and measure the presence of tyrosine kinase activity. ELISA is described, for example, in Voller, et al, 1980, "Enzyme-Linked Immunosorbent Assay": Manual of Clinical Immunology, 2d, ed ., Edited by Rose and Friedman, pp 359-371 Am. Soc. Of Microbiology, Washington, DC).

Those skilled in the art are well aware of the application of such an assay to measure the activity of a compound against non-receptor tyrosine kinases as well as other members of the receptor PTK family. To determine inhibitor selectivity, a universal PTK substrate (for example, a random copolymer of poly (Glu ₄ Tyr), 20,000-50,000 MW) was added at a concentration approximately twice the apparent Km of the assay to ATP ).

[635] PKC kinase source
[636] The catalytic subunit of PKC can be purchased from Calbiochem.
[637] PKC kinase assay assay
[638] The radioactive kinase assay was performed according to the published method (Reference: Yasuda, I., Kirshimoto, A., Tanaka, S., Tominaga, M., Sakurai, A., Nishizuka, Y.

[643] In vitro model for T cell activity
[644] In the case of activation by mitogen or antigen, T cells are induced to secrete IL-2, a growth factor that supports their subsequent proliferative step. Thus, as a surrogate for T cell activation, IL-2 from primary T cells or appropriate T cell lines can be measured or cell proliferation measured. Both of these assays are well described in the literature and their parameters are documented (cf. Current Protocols in Immunology, Vol 2, 7.10.1-7.11.2).
[645] In summary, T cells can be activated by incubation with allograft cells, and the process is termed a one-way mixed lymphocyte reaction. Reagents and stimulants Peripheral blood mononuclear cells are purified by Ficoll-Hypaque gradient (Pharmacia) according to the manufacturer's instructions. Stimulator cells are mitotically inactivated by mitomycin C (Sigma) or gamma irradiation. Reactants and stimulator cells are co-cultured in the presence of test compound at a ratio of 2: 1. Generally, 10 ⁵ reactants are mixed with 5 x 10 ⁴ stimulants and plated in 200 μl volumes in U-shaped bottom microtiter plates (Costar Scientific). Cells are cultured in heat-inactivated fetal bovine serum (Hyclone Laboratories) or in RPMI 1640, 5x10 ^-5 M mercaptoethanol and 0.5% DMSO supplemented with pooled human AB serum from a male donor. The cultures are pulsed with 0.5 μCi of ³ H thymidine (Amersham) one day prior to harvesting (generally 3 days). The cultures are harvested (beta-plate harvester, Wallac) and isotope adsorption assay is performed with liquid scintillation (Beta plate, Wallac).
[646] The same culture system can be used to measure T cell activation for measurement of IL-2 production. After incubation for 18-24 hours, the supernatant is removed and the IL-2 concentration is measured by ELISA (R and D Syatems) according to the manufacturer's instructions.
[647] In vivo model of T cell activation
[648] The in vivo efficacy of the compounds can be tested in animal models known to directly measure T cell activation or T cells found to be the working cells for this. T cells can be activated in vivo by binding a certain amount of T cell receptor with monoclonal anti-CD3 antibody (Ab). In this model, BALB / c mice receive 10 mg of anti-CD3 Ab intraperitoneally 2 hours prior to salvage. Animals receiving the test drug are pretreated with a single dose of compound one hour prior to administration of anti-CD3 Ab. Serum levels of the inflammatory cytokines interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α), which are T cell activation indicators, are measured by ELISA. A similar model performs in vivo T cell priming using specific antigens, such as keyhole limpet hemocyanin (KLH), and subsequent secondary inoculation of the lymph node cells with the same antigen. As described above, measurement of cytokine production is used to analyze the activated state of the cultured cells. In summary, C57BL / 6 mice are immunized subcutaneously with 100 μg KLH emulsified in complete Freud's adjuvant (CFA) on day 0. Animals are pretreated with compound 1 day before and after immunization on days 1, 2 and 3 after immunization. Drained lymph nodes are harvested at day 4 and their cells are cultured in tissue culture medium (RPMI 1640 supplemented with 5 × 10 ^-5 M 2-mercaptoethanol and 0.5% DMSO, heat-inactivated fetal bovine serum (Hycloe Laboratory) X 10 < ⁶ > / ml for 24 hours and 48 hours. Culture supernatants are assayed for self-secreted T cell growth factor interleukin-2 (IL-2) and / or IFN-y levels by ELISA.
[649] Leading compounds can be tested from animal models of human disease. These are exemplified by experimental autoimmune encephalomyelitis (EAE) and collagen-induced arthritis (CIA). EAE models with similar aspects to human multiple sclerosis have been described in both mice and mice (FASEB J. 5: 2500-2566, 1991; Rat Model: Lab. Invest. 4 (3): 278, 1981 ; Rodent models: J. Immonol 146 (4): 1163-8,1991). In summary, mice or rats are immunized with a herbal basic protein or a neurogenic peptide derivative thereof, and an emulsion of CFA. An acute disease can be induced by the addition of a bacterial toxin, such as bordetella pertussis . Relapsing / remitting disease may be induced by adoptive transfer of T cells from an MBP / peptide immunized animal.
[650] CIA can be immunized with type II collagen in DBA / 1 mice (reference: J. Immunol: 142 (7): 2237-2243). Mice show signs of arthritis early about 10 days after antigen challenge and can be recorded for as long as 90 days after immunization. In both the EAE and CIA models, the compound may be administered prophylactically or at the onset of the disease. Effective drugs should reduce the severity and / or onset.
[651] One or more angiogenic receptor PTKs, and / or protein kinases, such as lcks involved in modulating inflammatory responses, may reduce the severity and onset in these models.
[652] The compounds may also be used in a mouse allograft model, skin (reference: Ann. Rev. Immunol., 10: 333-58, 1992; Transplantation: 57 (12): 1701-17D6, 1994) J. Anat .: 113: 273, 1963). In summary, a sufficient thickness of the epidermal graft can be transplanted from C57BL / 6 mice to BALB / c mice. These grafts are examined daily for evidence of rejection starting on day 6. In a rat newborn heart transplant model, a newborn heart is ectopically transplanted from C57BL / 6 mice into the auricle of mature CBA / J mice. The heart begins to pulsate 4 to 7 days after transplantation, and rejection can be visualized using a dissecting microscope to observe the discontinuation of beating.
[653] Cell receptor PTK analysis
[654] The following cell assays were used to determine the level and effect of the activity of other compounds of the invention on KDR / VEGFR2. Analogous receptor PKT assays using specific ligand stimulation could be designed following the same method for other tyrosine kinases using techniques known in the art.
[655] Western blot measurements on human umbilical vein endothelial cells (HUVEC)
[656] 1. HUVEC cells (from pooled donors) were purchased from Clontics (Clonetics, Sandiego, Calif.) And cultured according to the manufacturer's instructions. Only the initial step (3-8) was used for this analysis. Cells were cultured in 100 mm dishes (Falcon for tissue culture; Becton Dickinson; Plymouth, England) using full EBM medium (Clonetics).
[657] 2. In order to evaluate the inhibitory activity of the compounds, the cells were Xin trip, a 6-well cluster plates; were seeded 0.5-1.0 × 10 ⁵ cells / well in each well of (Costar Cambridge, MA).
[658] 3. 3-4 days after seeding, the plates became 90-100% fluffy. The medium was removed from the wells, and the cells were washed with 5-10 ml of PBS and incubated for 18-24 hours with 5 ml of EBM-based medium without additional feed (i. E., Serum starvation).
[659] 4. A series of dilutions of inhibitor were added to 1 ml of EBM medium (25 μM, 5 μM, or 1 μM final concentration for cells) and incubated at 37 ° C for 1 hour. Human recombinant VEGF ₁₆₅ (R & D System) was then added to all wells in 2 ml of EBM medium to a final concentration of 50 ng / ml and incubated at 37 [deg.] C for 10 min. Background phosphorylation and phosphorylation by VEGF were analyzed using VEGF alone or untreated control cells.
[660] Next, all wells are washed with 5-10 ml of cold PBS containing 1 mM sodium orthovanadate (Sigma), the cells are lysed and incubated with protease inhibitor (PMSF 1 mM, aprotinin 1 ug / ml, pepstatin 1 ug / ml (50 mM Tris-HCl pH7, 150 mM NaCl, 1% NP-40, 0.25% sodium deoxycholate, 1 mM EDTA (pH 7.0) containing 1 μg / ml of rubetin, 1 mM Na vanadate, 1 mM Na fluoride) ), And 1 [mu] g / ml Dase (chemicals from Sigma Chemical Company, St Louis, MO). The lysate was centrifuged at 14,000 rpm for 30 minutes to remove nuclei.
[661] Next, the same amount of protein was precipitated by adding cold (-20 ° C) ethanol (2 volumes) for at least 1 hour or up to overnight. The pellet was resuspended in a Laemli sample buffer containing 5% beta mercaptoethanol (BioRad; Hercules, Calif.) And boiled for 5 minutes. Proteins were separated by polyamide gel electrophoresis (6%, 1.5 mm Novex, Sandiego, Calif.) And transferred to the nitrocellulose membrane using the Novex system. Protein was blocked with anti-KDR polyclonal antibody (C20, Santa Cruz, CA) or anti-phosphotyrosine monoclonal antibody (4G10, Upstate Biotechnology, Lake Placid, NY) after blocking with bovine serum albumin (3% ≪ / RTI > overnight at 4 < 0 > C.

After incubation for 1 hour with the HRP-condensed F (ab) _{2 of the} wash and goat anti-rabbit or goat- Lt; / RTI > A specific example of the present invention significantly inhibited cellular VEGF-induced KDR tyrosine kinase phosphorylation at a concentration of less than 50 μM.
[662] In vivo model of uterine edema
[663] This assay measures the ability of a compound to inhibit the rapid increase in uterine weight in mice that occurs within the first few hours after stimulation of estrogen. This early onset of uterine weight gain is known to be caused by edema caused by increased permeability of the uterine vasculature. Cullinan-Bove and Koss (Reference: Endocrinology (1993), 133: 829-837) demonstrated a close temporal relationship between increased expression of estrogen-stimulated uterine edema and intrauterine VEGF mRNA . These results have been confirmed by the use of neutralization of monoclonal antibodies against VEGF, which significantly reduces the rapid increase in uterine weight following estrogen stimulation (WO 97/42187). Thus, such a system contributes as a model for the inhibition of in vivo VEGF signaling and the associated hyperpermeability and edema.
[664] Materials: All hormones were purchased as lyophilized powders from Sigma (St. Louis, Mo.) or Cal Biochem (La Jolla, Calif.) And prepared according to the supplier's instructions.
[665] The vehicle compound (DMSO, Cremaphor EL) was purchased from Sigma.
[666] Mice (Balb / c, 8-12 weeks old) were purchased from Taconic (Germantown, NY) and housed in non-toxic animals according to the Commission's Animal Care and Use Committe Guidelines .
[667] Way:
[668] Day 1: Balb / c mice were intraperitoneally (i.p.) injected with 12.5 units of serum gonadotropin (PMSG) in pregnant females.
[669] Day 3: Human chorionic gonadotropin (hCG) is administered to mice via i.p. Injected.
[670] Day 4: Mice were randomly divided into two groups of 5-10 mice. The test compounds were tested for i.p., i.v., or p.o. 1 mg / kg, depending on solubility and vehicle. The vehicle control group was administered vehicle only and the two groups were not treated.
[671] After 30 minutes of experiment, one of the vehicle group and the untreated group was ip injected with 17 [beta] -estradiol (500 [mu] g / kg). After 2-3 days, the animals were killed by inhalation of CO ₂ . After the incision of the center line, each uterus was separated and removed by cutting the connection between the uterus and fallopian tubes just below the cervix. Before weighing, lipids and connective tissue were carefully removed, taking care not to damage the entire uterus. As a result of the researcher 's test, the saliency was measured. A non-stimulated control was used to monitor the estradiol response.
[672] The results demonstrate that certain compounds of the invention inhibit the formation of edema when administered systemically via various routes.
[673] Certain compounds of the invention, which are inhibitors of angiogenic receptor tyrosine kinases, have also been shown to be active in the angiogenic Matrigel transplantation model. The matrigel angiogenesis model involved the formation of new blood vessels within an apparent " marble " of subcutaneous implanted extracellular matrix induced by the presence of angiogenic proangiogenic factors producing tumor cells (1992), 67 (4), 519-528, Anat. Rec. (1997), 249 (1), 63-73; Int. J. Cancer (1995), 63 (5), 694-701, Vasc Biol. (1995), 15 (11) 1857-6). The model is preferably performed over 3 to 4 days and the endpoint is visual / visual scoring of the angiogenesis, microscopic microvascular density measurement, and hemoglobin quantitation (Drabkin method) followed by an inhibitor-free And removal of graft versus control from the animals.
[674] Certain compounds of the invention that inhibit one or more tumorigenic, primitive tumorigenic, or proliferative dependent protein kinases, or angiostatic receptors PKT, also inhibit the proliferation of primary mouse, mouse or human xenograft tumors in mice, Which inhibited the metastasis of mouse models.
