Description

Technical Field

[0001] This invention relates to the field of pharmaceutical chemistry, specifically to a methionine adenosine transferase inhibitor, its preparation method, and its application in the pharmaceutical field. Background Technology

[0002] Loss-of-function mutations in tumor suppressor genes are very common, but there are very few therapies that selectively target these mutations. This is easily understood, as the missing proteins are difficult to inhibit directly to achieve therapeutic effects. Targeted therapy for tumor suppressor genes that are inactivated due to homozygous deletion is particularly challenging because the lack of residual proteins renders treatment strategies that directly activate, stabilize, or repair the tumor suppressor genes ineffective.

[0003] Methionine adenosine transferase (MAT), also known as S-adenosylmethionine synthase, is a cellular enzyme that catalyzes the synthesis of S-adenosylmethionine (SAM or AdoMet) from methionine and ATP, and is considered the rate-limiting step in the methionine cycle. SAM is the alanine donor in polyamine biosynthesis and a major methyl donor for DNA methylation, participating in gene transcription, cell proliferation, and the generation of secondary metabolites. The MAT gene can be divided into the MAT1A and MAT2a genes, encoding the only enzyme capable of catalyzing the synthesis of SAM—MAT. There are three isoenzymes of MAT: MAT I, MAT III, and MAT II. The first two are products encoded by the MAT1a gene, and the last is a product encoded by the MAT2a gene. The MAT1a gene is mainly expressed in the adult liver, while the MAT2a gene is widely expressed in human tissues other than the liver. More and more studies have found that the MAT2a protein is also highly expressed in other cancer tissues or cells, such as breast cancer, colorectal cancer, leukemia and lymphoma. Silencing the MAT2a gene leads to the death of the corresponding cancer cells, indicating that the MAT2a protein has the potential to be a therapeutic target.

[0004] Methylthioadenosine phosphorylase (MTAP) is an enzyme expressed in all normal tissues that catalyzes the conversion of methylthioadenosine (MTA) to adenine and 5-methylthio glucose-1-phosphate. Many malignant cell lines lack MTAP activity, and loss of MTAP activity has been detected in a large number of primary lesions, including gliomas, melanomas, pancreatic cancers, non-small cell lung cancers, bladder cancers, astrocytomas, osteosarcomas, head and neck cancers, myxoid chondrosarcomas, ovarian cancers, endometrial cancers, breast cancers, soft tissue sarcomas, and non-Hodgkin's lymphomas. When MTAP is absent, MTA accumulates to about 100 μM in the cell, and the cell begins to export MTA. The abnormal accumulation of MTA leads to the vulnerability of Protein Arginine Methyltransferase 5 (PRMT5). Since PRMT5 utilizes SAM as a methyl donor substrate, inhibiting MAT2a activity decreases the concentration of SAM in the cell, thereby selectively reducing PRMT5 methylation activity in MTAP-deleted cells below the threshold level required for growth. Thus, inhibiting MAT2a activity can produce a combined lethality in MTAP-deleted cells by inhibiting PRMT5 activity, and can provide therapeutic benefits for a variety of cancers. SUMMARY

[1296] Collect blood from the submandibular vein or other suitable means, and collect about 0.03 mL of each sample, and anticoagulate with sodium heparin. Place the blood sample on ice after collection, and centrifuge to separate the plasma within 1 hour (centrifugation conditions: centrifugal force 6800 g, 6 minutes, 2-8°C). Store the collected plasma sample in a -80°C refrigerator before analysis, and continue to store the remaining plasma sample in a -80°C refrigerator after analysis.

[1297] 7. Bioanalysis and data processing

[1298] Detect the blood drug concentration of the test subject, and record 0 for BLQ (the lowest detection limit) when drawing the plasma drug concentration-time curve. Calculate the concentration before administration as 0; calculate the previous BLQ (including “No peak”) as 0; and do not calculate the subsequent BLQ (including “No peak”) for Cmax. Calculate the pharmacokinetic parameters such as AUC(0-t), T max , and Cmax by using the blood drug concentration data at different time points and WinNonlin. 1 / 2
