Descriptive Report of the Invention Patent for SYNTHESIS OF MCL-1 INHIBITOR.
Background [001] Myeloid Cell Leukemia 1 (Mcl-1) is an important anti-apoptotic member of the BCL-2 protein family and a central regulator of cell survival. Amplification of the MCL1 gene and / or overexpression of the Mcl-1 protein has been observed in multiple types of cancer and is usually implicated in tumor development. In fact, MCL1 is one of the most frequently amplified genes in human cancer. In many malignancies, Mcl-1 is a critical survival factor and has been shown to mediate drug resistance for a variety of anti-cancer agents.
[002] Mcl-1 promotes cell survival by binding to pro-apoptotic proteins such as Bim, Noxa, Bak and Bax and neutralizing their death-inducing activities. Thus, inhibition of Mcl-1 releases these pro-apoptotic proteins, often leading to the induction of apoptosis in Mcl-1-dependent tumor cells to survive. Thus, targeting Mcl-1 therapeutically alone or in combination with other therapies is a promising strategy for treating a plurality of malignancies and for overcoming drug resistance in many human cancers. The compound chemically called (/ A ) - (+) - 17-chloro-5,13,14,22-tetramethyl-28oxa-2,9-dithia-5,6,12,13,22-penta-azaheptacyclo [27.7.1.1 4 ' 7 .0 11 ' 15 .0 16 '21 .

The mixture was cooled and stirred at 0 ± 5 ° C for at least 2 hours. Residual solids were removed by filtration to give the crude 3-mercaptonaphthalene-1-ol dissolved in the filtrates (also containing a large amount of triphenylphosphine oxide), which were refilled in the reactor followed by DMAP (0.84 kg, 6, 9 mol). Keeping the temperature below 25 ° C, triethylamine (21.0 kg, 207 mol) and then acetic anhydride (17.6 kg, 173 mol) were gradually added. The mixture was stirred for 2 h at 15-20 ° C and then distilled under reduced pressure to less than 85 L, not heating above 45 ° C. DCM (85 L) was added and then the mixture was distilled under reduced pressure to less than 85 L, not heating above 40 ° C. More DCM (170 L) was added and then the mixture was washed with water (170 L), followed by aq. (17% by weight, 170 L). The lower organic phase was distilled under reduced pressure to less than 51 L, not heating above 40 ° C. Then, three cycles of diluting the solution with MeOH (85 L) and distillation under reduced pressure to less than 51 La under 40 ° C were completed to give a methanolic solution of 3- (acetylthio) naphthalen-1-yl (Intermediate 11), 40.9 kg, 31.3% by weight, 49.2 mol) with 71% yield. The solution, which also contains a large amount of triphenylphosphine oxide, was used directly in the preparation of Intermediate 12.

[0090] DSC analysis indicated that Form A undergoes an endothermic desolvation event with a start at about 121 ° C and a peak at about 158 ° C, followed by an endothermic melting / decomposition event with a start at about 181 ° C and a peak at about 194 ° C. TGA indicated that Form A exhibits a mass loss of about 4.0% by heating from about 25 ° C to about 160 ° C. A representative DSC / TGA thermogram of Form A is

[0091] Analysis of the structure of the isolated crystals confirmed that Form A is a monohydrate form. Crystallographic data: P2 monoclinic spatial group (1), unit cell dimensions: a = 13.83 (3) A, b = 7.578 (14) A, c = 33.57 (6) A, β = 90.23 ( 2) °, V = 3518 (12) A 3 . Powder X-Ray Diffraction Analysis (XRPD) [0092] XRPD analysis was performed using a Bruker D4 diffractometer, which is commercially available from Bruker AXS Inc ™ (Madison, Wisconsin). XRPD spectra were obtained by assembling a sample (approximately 20 mg) of the material for analysis in a single assembly on a single silicon crystal wafer (for example, a Bruker X-ray diffraction sample holder with zero silicon bottom ) and spreading the sample in a thin layer with the aid of a microscope slide. The sample was rotated at 30 revolutions per minute (to improve the counting statistics) and irradiated with X-rays generated by a copper tube with long-fine focus operated at 40 kV and 40 mA with a wavelength of 1, 5406 Angstroms (ie, about 1.54 Angstroms). The sample was exposed for 1 second by an increment of 0.02 degrees 2-theta (continuous scan mode) over the range of 2 degrees to 40 degrees 2-theta in theta-theta mode. The processing time was 31 min, 41 s.
[0093] XRPD 20 values may vary within a reasonable range, for example, within the range ± 0.2 ° and such XRPD intensities may vary when measured for essentially the same crystalline form for a variety of reasons, including, for example , preferred orientation. The principles of XRPD are described in publications, such as, for example, Giacovazzo, C. et al. (1995), Fundamentals of Crystallography, Oxford University Press; Jenkins, R. and Snyder, R. L. (1996), Introduction to X-Ray Powder Diffractometry,

DSC analysis [0094] DSC analysis was performed on samples prepared according to standard methods using a DSC Q SERIES ™ Q1000 calorimeter available from TA Instruments® (New Castle, Delaware). One sample (approximately 2 mg) was weighed in an aluminum sample container and transferred to the DSC. The instrument was purged with nitrogen at 50 mL / min and data were collected between about 22 ° C and 300 ° C, using a dynamic heating rate of about 10 ° C / minute. The thermal data were analyzed using standard software, for example, Universal V.4.5A from TA INSTRUMENTS®.
Thermogravimetry Analysis (TGA) [0095] TGA was performed on samples prepared according to standard methods using a Q SERIES ™ Q5000 thermogravimetry analyzer from TA Instruments INSTRUMENTS® (New Castle, Delaware). A sample (approximately 5 mg) was placed in an aluminum sample container and transferred to the TGA oven. The instrument was purged with nitrogen at 50 mL / min and data were collected between 25 ° C and 300 ° C, using a dynamic heating rate of 10 ° C / minute. The thermal data were analyzed using standard software, for example, Universal V.4.5A from TA INSTRUMENTS®.

61/61 with Mcl-1 inhibitors. On the first day, 3000 (MOLP-8, KMS12-BM, MV4; 11) or 1250 (NCI-H23) cells / well were seeded with 50 µl of growth medium (IMDM + 10% FBS + 2 mM L-Glu for MV4; 11 and RPMI-1640 + 10% FBS + 2 mM L-Glu for all others) in 384-well white microplates and incubated overnight (37 ° C, 5% CO2, 80% RH ). On the second day, the cells were treated with Compound 1 using an ECHO acoustic liquid handler (10-point serial dilution in semi-log, 31.5 μΜ maximum concentration, 0.3% final DMSO concentration). After 6 h of incubation (37 ° C, 5% CO2, 80% RH), 25 μΙ_ of Caspase-GIo 3/7 reagent (Promega) was added to each well and the plates were incubated at room temperature for 30 min protected from light. Luminescence was recorded using an Infinite M200 microplate reader (Tecan) with an integration time of 100 ms. IC50 values were calculated using the GeneData analysis software and are shown in Table 2 below.
