[003] Autotaxin (ATX) is a secreted enzyme also called ectonucleotide pyrophosphatase / phosphodiesterase 2 or lysophospholipase D which is important for converting lysophosphatidyl choline (LPC) to the bioactive signaling molecule of lysophosphatidic acid (LPA). It has been demonstrated that plasma levels of LPA are perfectly related to ATX activity and for this reason ATX is believed to be an important source of extracellular LPA. Initial experiments with an ATX inhibitor prototype demonstrated that such a compound is capable of inhibiting the synthesis activity of LPA in mouse plasma. The work done in the 1970s and early 1980s demonstrated that LPA can elicit a wide range of cellular responses; including contraction of smooth muscle cells, platelet activation, cell proliferation, chemotaxis and others. LPA mediates its effects via signaling to several G protein-coupled receptors (GPCRs); the first limbs were originally called Edg receptors (endothelial cell differentiation gene) or ventricular zone 1 gene (vzg-1), but are now called LPA receptors. The prototypical group now consists of LPA1 / Edg-2 / VZG-1, LPA2 / Edg-4 and LPA3 / Edg-7. Recently, three additional LPA receptors have been described, LPA4 / p2y9 / GPR23, LPA5 /

GPR92 and LPA6 / p2Y5, which are more closely related to purinergic receptors selective for nucleotides than to prototypes of LPA receptors13. The ATX-LPA signaling axis is involved in a wide range of physiological and pathophysiological functions, including, for example, nervous system function, vascular development, cardiovascular physiology, reproduction, immune system function, chronic inflammation, metastasis and tumor progression. , organic fibrosis as well as obesity and / or other metabolic disorders, such as diabetes mellitus. For this reason, increased ATX activity and / or increased LPA levels, altered LPA receptor expression and altered responses to LPA may contribute to the onset, progression and / or outcome of several different pathophysiological conditions related to ATX / LPA axis.
[004] Carbonic anhydrases (AC) are a family of zinc-dependent enzymes, which catalyze the balance between carbon dioxide and hydrogen and hydrogen and a proton. The CA reaction is involved in many physiological and physiological processes. The inhibition of carbonic anhydrase is useful for the treatment of eye conditions, reduced blood flow conditions, cancer, edema and inflammatory conditions, including bacterial infection.

7/132 carbonic anhydrase is useful for the treatment of eye conditions, reduced blood flow conditions, cancer, edema and inflammatory conditions, including bacterial infections.
[006] Double-acting ATX / CA inhibitors are expected to reduce intraocular pressure by facilitating two independent pathways, such as inhibiting the production of aqueous humor (HA) by inhibiting AC in the ciliary body and facilitating HA flow by inhibiting of ATX within the AH drainage system. Under conditions of vascular leakage in the eye, such as diabetic retinopathy, age-related macular disease or retinal vein occlusion, CA levels have been shown to increase in the eye and facilitate pH increase. This is expected to activate many hydrolytic enzymes that can contribute to the progression of the disease, including ATX, suggesting further inhibition of ATX, by shifting to the optimum pH.

Human 60/132 (hCA-II) was measured using an absorbance method using 4-nitrophenyl acetate (4-NPA) as a substrate. 4-NPA can be catalyzed by active hCA II by means of a zinc hydroxide mechanism. The nitrophenolate in the products can be ionized to generate a bright yellow anion with high absorbance under 348 at 400 nm, as described in the literature (Armstrong et al., J. Biol. Chem. 1966, 241, 5137-5149). OD340 nm was chosen to detect the conversion of the substrate hCA II.
