Description

TECHNICAL FIELD

[0001] The present application relates to a compound for treating cancer, in particular to a methionine adenosyltransferase 2A inhibitor, a preparation method thereof, a pharmaceutical composition comprising the same, and pharmaceutical use thereof. BACKGROUND

[0002] Methionine adenosyltransferase (MAT), also known as S-adenosylmethionine synthetase, has the major biological function of catalyzing the reaction of methionine with ATP to produce a biological methyl donor S-adenosylmethionine (SAM, AdoMet, or SAMe). The MAT-catalyzed reaction is considered to be an important rate-limiting step in the methionine metabolic cycle.

[0003] The MAT family includes three family members, MAT1A, MAT2A, and MAT2B. MAT1A is specifically expressed in human liver, while MAT2A and MAT2B are widely distributed in multiple human tissues. In normal liver cells, there is a dynamic equilibrium between MAT1A and MAT2A, which together maintain intracellular SAM homeostasis, whereas in hepatocellular carcinoma (HCC), MAT1A expression is abnormally down-regulated, and MAT2A expression is abnormally up-regulated. This gene expression change from MAT1A to MAT2A promotes cancer invasion and metastasis, and is closely related to increased metastasis and relatively poor recurrence-free survival (RFS) of HCC patients. See, e.g., Ruizhi Wang et al., Molecular Carcinogenesis 57 (9), (2018) 1201-1212. In addition to hepatocellular carcinoma, the abnormally increased expression level of MAT2A is also present in various tumors such as gastric cancer, colorectal cancer, and pancreatic cancer, and is closely related to the development and progression of tumors. MAT2A plays an important role in the pathogenesis of various tumors, and gene silencing of MAT2A can inhibit the proliferation of cancer cells such as liver cancer cells or gastric cancer cells and induce apoptosis. Therefore, MAT2A has become a target for drugs of antitumor therapy. See, e.g., T. Li et al., J. Cancer 7 (10) (2016) 1317-1327 and T. Zhang et al., Acta Histochemica 115 (2013) 48-55.

[0004] Further, it has been reported that MAT2A is a synthetic lethal target in MTAP-deficient cancer. MTAP, i.e., S-methyl-5'-thioadenosine phosphorylase, is widely distributed in normal tissues and cells, and mainly catalyzes the conversion of methylthioadenosine (MTA) to 5'-methylthioribose-1-phosphate (MTRP) and adenine. The process is an important procedure in the methionine salvage pathway in the human body. The gene encoding human MTAP is located in the chromosome 9p21 region. Studies have shown that the chromosome 9p21 region has a homozygous deletion frequency in all tumors of about 15%, and the deletion frequency varies among different tumors. The cancer with relatively high MTAP deletion frequency includes glioma, mesothelioma, esophageal cancer, bladder cancer, pancreatic cancer, melanoma, nonsmall cell lung cancer, head and neck cancer, cholangiocarcinoma, esophagogastric cancer, osteosarcoma, brain diffuse glioma, gastric cancer, adrenocortical carcinoma, breast cancer, thymus cancer, hepatocellular carcinoma, ovarian cancer, renal cell carcinoma, and the like. Further, K Marjon et al. found that S-methyl-5'-thioadenosine phosphorylase (MTAP)-deficient cancer was more sensitive to signaling pathways targeting MAT2A / PRMT5 / RIOK1 (Cell Reports Volume 15, Issue 3, 2016, 574-587). When MTAP is deleted, the metabolic pathway of MTA is inhibited, resulting in the accumulation of MTA in vivo in a large amount. The accumulation of MTA in a large amount will partially inhibit the activity of PRMT5. MAT2A is a key enzyme for SAM production in cells. Inhibition of MAT2A activity results in SAM reduction, causing PRMT5 to lack the corresponding substrate. Therefore, in MTAP-deficient tumor cells, inhibition of MAT2A further inhibits the methylation function of PRMT5, which in turn causes defects in RNA cleavage, gene expression, and chromosomal integrity, thereby inhibiting tumor cell growth.

[0005] Given that MAT2A is abnormally expressed in various human tumors (such as liver cancer, pancreatic cancer, gastric cancer, and colon cancer), and inhibition of MAT2A can selectively reduce the proliferative capacity of MTAP-deficient tumor cells and has weak effect on normal cells with MTAP normally expressed, the development of MAT2A inhibitors can be used as an effective tumor treatment method.

[0006] The present application provides an effective methionine adenosyltransferase 2A inhibitor, a preparation method thereof, a pharmaceutical composition comprising the same, and pharmaceutical use thereof, in particular for treating MTAP-deficient cancer. SUMMARY

[0634] Experimental Example 1: Bioactivity Assay of Compound of the Present Application

[0635] MAT2A inhibitory activity

[0636] MAT2A catalyzes the reaction of L-methionine and ATP to generate S-adenosylmethionine (SAM), inorganic phosphonic acid, and inorganic diphosphonic acid. Malachite green reacts with inorganic phosphonic acid to generate a green product, and the enzyme activity of MAT2A can be indirectly reflected by detecting the content of the inorganic phosphonic acid in a sample.

[0637] The test compounds were formulated using DMSO and diluted 1:3 diluted through 10 concentration points to give a final starting concentration in the reaction system of 1000 nM. The test compounds at different concentrations described above were transferred to a 384-well plate. Experimental buffer (50 mM HEPES pH 7.5, 50 mM KCl, 10 mM MgCl2, 10 mM DTT) was prepared. 2* MAT2A recombinant protein was prepared using the buffer and added to a 384-well plate. A mixed solution of 2* L-methionine and ATP was prepared using the buffer, and added to a 384-well plate. The enzymatic reaction was started, and the reaction was carried out at room temperature for 60 min. 20 uL of a colorimetric detection reagent was added to the above system, and incubated at room temperature for 15 min. The absorbance at 630 nm was measured. The inhibition rate of the compound on the enzyme activity was calculated, and the inhibition rate value and the logarithm value of the compound concentration were fitted using non-linear regression (dose response-variable slope) to give the IC50 value of the test compound.

[0638] In the present application, the test compounds were tested using the above assay method, and the test compounds were scored according to the IC50 value: (A) less than 100 nM; (B) between 100 nM and 1 uM; (C) greater than 1 uM, and (NT) IC50 value was not tested, as shown in Table 1.

[0639] Cell symmetric dimethylarginine (SDMA) test

[0640] MAT2A catalyzes the reaction of L-methionine and ATP to generate SAM, inorganic phosphonic acid, and inorganic diphosphonic acid. SAM is an important methyl donor, and is a substrate of arginine methyltransferase 5 (PRMT5). PRMT5 catalyzes SDMA modification of multiple proteins within a cell. The intracellular SDMA modification level was detected by ICW (In-cell Western), and the inhibition of the test compound on the enzymatic activity of intracellular MAT2A was indirectly reflected.

[0641] In the present application, the human colon cancer cell line HCT116 and the corresponding HCT116-MTAP-knockout cell line were seeded into a 96-well cell culture plate at an appropriate cell density. After 24 h, the cells were treated using the test compounds diluted 1:4 fold at the highest concentration of 6 uM for 6 gradients, and a DMSO treatment group was set up separately. The cells were cultured in a 37 °C / 5% CO2 incubator for 4 days. To test the inhibitory activity of the test compounds against tumor cell SDMA, the medium was discarded, and the plate was washed 3 times with PBST. 4% paraformaldehyde was then used at room temperature for fixation for 20 min. The fixation solution was discarded, the plate was washed 3 times with PBST, and a special blocking solution was added to each well for blocking at room temperature for 2 h. The blocking solution was discarded. After the plate was washed 3 times with PBST, the plate was incubated with SDMA antibody at 4 °C overnight. The next day, the plate was washed 3 times with PBST. The secondary antibody and DRAQ5 were diluted to an appropriate concentration with the blocking solution, and incubated at room temperature for 2 h; the plate was washed 3 times with PBST, and the fluorescence signals at 700 nm and 800 nm were detected using a Li-COR Odyssey two-color near-infrared laser imager.

[0642] The data was then processed. After the corresponding background value was subtracted from each well, statistical analysis was performed on the 800 nm / 700 nm ratio for each well, a sigmoidal dose-inhibition curve was plotted using a non-linear regression model, and IC50 values were fitted and calculated. Inhibition Rate (%) = (1-SDMA dose / SDMA DMSO control) *100. SDMA dose is the value of the drug treatment group, and SDMA DMSO control is the value of the DMSO control group.

[0643] The exemplary compounds disclosed herein were tested in the above assay and determined to inhibit SDMA with IC50 based on the following scores: (A) less than 200 nM, (B) between 200 nM and 1 uM, (C) between 1 uM and 3 uM, (D) greater than 3 uM, and (NT) not tested, as shown in Table 1 below.

[0644] As can be seen from Table 1, most of the compounds had good inhibitory activity against MAT2A protein, good SDMA inhibitory activity against MATP-knockout HCT116 cells, and a certain selectivity against MATP wild-type HCT116 cells.

[0645] Tumor cell proliferation inhibition assay

[0646] After the HCT116-MTAP-knockout (- / -) cell strain, the HCT116-MTAP wild-type (+ / +) -cell strain, the DOHH-2 cell strain, or the Hut-78 cell strain was treated with the test compound for 5 days, the ATP level was measured using a CellTiter-Glo kit of Promega to evaluate the inhibition of the test compound against the growth of the tumor cell strain.

[0647] In the present application, the HCT116-MTAP-knockout (- / -) cell strain, the HCT116-MTAP wild-type (+ / +) -cell strain, the DOHH-2 cell strain, or the Hut-78 cell strain was seeded into a 96-well cell culture plate at an appropriate cell density. After 24 h, the cells were treated using the test compounds diluted 1:3 fold at the highest concentration of 10 uM for 10 gradients, and a DMSO treatment group was set up separately. The cells were cultured in a 37 °C / 5% CO2 incubator for 5 days. To test the proliferation inhibition of the test compound on tumor cells, the cells were equilibrated at room temperature for 10 min, followed by addition of 30 uL of cell proliferation assay reagent CellTiter-Glo(CTG) per well. The plate was shaken for 2 min, and incubated in the dark for 15 min. Chemiluminescence values were read using a Thermo Varioskan LUX-3020 multifunctional microplate reader for conversion to proliferation indices to calculate the inhibition rate of the compound on tumor cell proliferation, and the inhibition rate value and the logarithm value of the compound concentration were fitted using non-linear regression (dose response-variable slope) to give the IC50 value of the compound.

[0648] The exemplary compounds disclosed herein were tested in the above assay and determined to inhibit cell proliferation with IC50 based on the following scores: (A) less than 500 nM, (B) between 500 nM and 2 uM, (C) greater than or equal to 2 uM, and (NT) not tested, as shown in Table 2.

[0650] Experimental Example 2: Stability Test in Liver Microsomes

[0651] Phase I metabolic stability of the test compounds in liver microsomes of CD-1 mice, Sprague-Dawley rats, beagle dogs, cynomolgus monkeys, and humans was assessed.

[0652] Experimental system: The animal and human liver microsomes used in the test system were purchased from Xenotech, Corning, or other qualified suppliers and stored in a freezer at a temperature below -60 °C prior to use.

[0653] Brief introduction of the experiment: The test samples and control compounds were separately incubated with animal and human liver microsomes at 37±1 °C for a period of incubation time up to 60 min. The samples were removed at the indicated time points, and the reaction was terminated with acetonitrile or other organic solvents containing an internal standard. After centrifugation, the resulting supernatant was assayed by liquid chromatography-tandem mass spectrometry (LC-MS / MS).

[0654] Experimental method:

[0655] 1. Preparation of buffer 73.21 g of dipotassium hydrogenphosphate trihydrate and 10.78 g of potassium dihydrogenphosphate were dissolved in 4000 mL of ultrapure water. The pH value of the solution was adjusted to 7.40±0.10 using 10% phosphoric acid or 1 M potassium hydroxide to a final concentration of 100 mM.

[0656] 2. Preparation of working solution The test sample powder was prepared into a stock solution with a certain concentration using DMSO or other organic solvents, which was then further diluted using a proper organic solvent. Control compounds testosterone, diclofenac, and propafenone were prepared into a 10 mM stock solution using DMSO, which was then further diluted using a proper organic solvent.

[0657] 3. Preparation of liver microsome solution Microsomes of each species were diluted to a 2X working solution using a 100 mM potassium phosphate buffer. The final concentration of the microsomes in the reaction system was 0.5 mg / mL.

[0658] 4. Preparation of reduced nicotinamide adenine dinucleotide phosphate (NADPH) regeneration system An appropriate amount of nicotinamide adenine dinucleotide phosphate (NADP) and isocitric acid (ISO) powder was weighed out, dissolved in a magnesium chloride solution, and shaken and mixed well. An appropriate amount of isocitrate dehydrogenase (IDH) was added, and the mixture was mixed well by gently turning upside down. The final concentrations in the reaction system were: 1 mM NADP, 1 mM magnesium chloride, 6 mM ISO, and 1 unit / mL IDH.

[0659] 5. Preparation of stop solution The stop solution was prepared using acetonitrile or other organic solvent containing an internal standard (tolbutamide or other suitable compounds). The prepared stop solution was stored in a freezer at a temperature of 2-8 °C.

[0660] 6. Incubation process Incubation was performed in a 96-well plate. 8 incubation plates were prepared and designated T0, T5, T15, T30, T45, T60, Blank60, and NCF60, respectively. The first 6 plates corresponded to reaction time points of 0, 5, 15, 30, 45, and 60 min, respectively. No test sample or control compound was added to the Blank60 plate, and samples were taken after 60 min of incubation. In the NCF60 plate, incubation was performed for 60 min using the potassium phosphate buffer instead of the NADPH regeneration system solution. Three replicates were made for samples in all conditions.

[0661] The microsomes and the test sample or control compound were mixed, and then the incubation plates Blank60, T5, T15, T30, T45, and T60 except for T0 and NCF60 were placed in a 37 °C water bath for pre-incubation for about 10 min. In the incubation plate T0, a stop solution was first added, followed by addition of the NADPH regeneration system working solution, and 98 uL of the potassium phosphate buffer was added to each sample well of the incubation plate NCF60 to initiate the reaction. After the pre-incubations of the incubation plates Blank60, T5, T15, T30, T45, and T60 were completed, 98 uL of the NADPH regeneration system working solution was added to each sample well to initiate the reaction. The reaction temperature was 37±1 °C, the final volume of the reaction was 200 uL, and the reaction system included 0.5 mg / mL microsomes, 1.0 uM substrate, 1 mM NADP, 6 mM ISO, and 1 unit / mL IDH.

[0662] At 5, 15, 30, 45, and 60 min, a cold stop solution containing an internal standard was separately added to the reaction plate to stop the reaction.

[0663] All the reaction plates after termination were shaken up and centrifuged for 20 min at 3220x g at 4 °C. After the supernatant was diluted according to a certain proportion, LC-MS / MS analysis was performed.

[0664] Sample analysis

[0665] Sample analysis was carried out by the liquid chromatography-tandem mass spectrometry (LC-MS / MS) method, and the standard curve and quality control sample were not included. Semi-quantitative determinations were made using the ratio of the analyte peak area to the internal standard peak area. The retention times of the analyte and internal standard, the chromatogram acquisitions and the integrals of the chromatograms were processed with software Analyst (Sciex, Framingham, Massachusetts, USA).

[0666] The CV for the internal standard peak area in each matrix in each analysis batch should be within 20%.

[0667] Data analysis

[0668] The in vitro elimination rate constant ke of the compound was obtained by converting the ratio of the peak area of the compound to the internal standard peak area in the following formula into the remaining rate: Remaining rate Peak area ratio of compound to internal standard at any time point ___________________________________________________________x 100 (%) = Peak area ratio of compound to internal standard at 0 min C, = C, . e-^- when C - t ^ ; , Ln 2       0 . 693 CLint (mic) = 0.693 / T1 / 2 / microsome protein content (microsome concentration mg / mL during incubation) CLint (liver) = CLint (mic) x microsome protein amount in liver (mg / g) x liver-to-body weight ratio

[0669] According to the well stirred model, the hepatic intrinsic clearance and hepatic clearance can be converted through the following formula. CL(liver) = (CLint(liver) * Qh) / (CLint(liver) + Qh)

[0670] Parameters in the formula are shown in Table 3. Table 3. Parameters in the data analysis formula Species Liver-to-body weight ratio (g / kg body weight) [1-2] Liver blood flow volume (Qh) (mL / min / kg) [1-2] Microsome protein amount (mg / g liver weight) Mice 88 90.0 Rat 40 55.2 Dog 32 30.9 45 Monkey 30 43.6 Human 20 20.7

[0672] Experimental Example 3: Metabolic Stability Test in Hepatocytes

[0673] This experimental example was used to test the metabolic stability of the compounds in hepatocytes.

[0674] A suspension of hepatocytes was prepared at 0.5 x 106 / mL with a pre-heated medium, then 198 pL of the pre-heated cell suspension was added to a 96-well plate. To each well of the 96-well plate, 2 pL of the test compound was added so that the final concentration was 1 pM, and 2 replicate wells were set. For the T = 0 min sample, the compound was mixed well with the cells for 1 min, then 25 pL of the sample was immediately added to 125 pL of a stop solution (an acetonitrile solution containing 200 ng / mL tolbutamide and 200 ng / mL labetalol) under an ice bath and mixed well. At the same time, all the plates were placed in an incubator at 37 °C with 5% CO2, with the shaker set at 600 rpm. The sample was mixed well at 15, 30, 60, and 90 min of incubation, respectively, and 25 pL of the sample was added to 125 pL of a stop solution (an acetonitrile solution containing 200 ng / mL tolbutamide and 200 ng / mL labetalol) under an ice bath, mixed well, and shaken at 500 rpm for 10 min. Subsequently, the plate was centrifuged for 20 min at 3220x g at 4 °C. After the centrifugation was completed, 80 pL of the supernatant from each well was transferred to another 96-well plate containing 240 uL of ultrapure water. Subsequently, analysis was carried out using LC-MS / MS, and intrinsic clearance (CLint) and halflife (T1 / 2) were calculated.

[0676] Experimental Example 4: Pharmacokinetic Test in Rats

[0677] In this example, the pharmacokinetic behavior of the compound after intravenous injection (IV) and intragastric (PO) administration in SD rats was tested.

[0678] On the day of administration, rats were weighed for actual body weight and the administration volume was calculated. Each compound was tested in two groups with 3 rats in each group, one group administered by single intravenous injection and the other by single intragastric administration. Whole blood samples were collected via the jugular vein at prescribed time points (0.25, 0.5, 1, 2, 4, 8, and 24 h after administration). After blood sample collection, the samples were transferred to labeled commercial sample tubes containing K2-EDTA (0.85-1.15 mg), followed by centrifugation (3200^ g, 4 °C, 10 min) and plasma collection. The plasma was transferred to a pre-cooled centrifuge tube, frozen in dry ice, and stored in an ultra-low temperature freezer at -60 °C or lower until the LC-MS / MS analysis.

Plasma drug concentration data for the compounds were processed in a non-compartmental model using WinNonlin Version 6.3 (Pharsight, Mountain View, CA) pharmacokinetic software. The relevant pharmacokinetic parameters were calculated using linear logarithmic trapezoid method.
