Synthesis method of alpha-hydroxyl-beta-amino acid simplex stereoscopic isomer
-
Paragraph 0009, (2018/06/28)
The invention relates to a synthesis method of an alpha-hydroxyl-beta-amino acid simplex stereoscopic isomer. The method mainly solves the technical problems that an existing synthesis method uses expensive chiral ligand or highly-toxic raw materials and is not suitable for industrial production. The method includes the steps of firstly, synthesizing substitutive alpha-hydroxyl-beta-amino acid despinner according to a literature method; secondly, stereoscopically and selectively synthesizing an alpha-hydroxyl-beta-amino acid simplex isomer of an (S,S) structure and an alpha-hydroxyl-beta-aminoacid simplex isomer of an (R,R) structure with penicillin G acylase. The method is suitable for preparing the alpha-hydroxyl-beta-amino acid simplex isomers efficiently at low cost.

Introduction of various modified prolines at P2 and optimization of the P1 side chain led to the discovery of SCH6 (24, Table 2), a potent ketoamide inhibitor of the HCV NS3 serine protease. In addition to excellent enzyme potency (Ki* = 3.8 nM), 24 was also found to be a potent inhibitor of HCV subgenomic RNA replication with IC50 and IC90 of 40 and 100 nM, respectively. Recently, antiviral activity of 24 was demonstrated with inhibition of the full-length genotype 2a HCV genome. In addition, 24 was found to restore the responsiveness of the interferon regulatory factor 3 (IRF-3) in cells containing HCV RNA replicons.

The NS3 protease of hepatitis C virus (HCV) has emerged as one of the best characterized targets for next-generation HCV therapy. The tetrapeptide 1 and pentapeptide 2 are α-ketoamide-type HCV serine protease inhibitors with modest potency. We envisioned

Hepatitis C virus (HCV) infection is the major cause of chronic liver disease, leading to cirrhosis and hepatocellular carcinoma, which affects more than 170 million people worldwide. Currently the only therapeutic regimens are subcutaneous interferon-α or polyethylene glycol (PEG)-interferon-α alone or in combination with oral ribavirin. Although combination therapy is reasonably successful with the majority of genotypes, its efficacy against the predominant genotype (genotype 1) is moderate at best, with only about 40% of the patients showing sustained virological response. Herein, the SAR leading to the discovery of 70 (SCH 503034), a novel, potent, selective, orally bioavailable NS3 protease inhibitor that has been advanced to clinical trials in human beings for the treatment of hepatitis C viral infections is described. X-ray structure of inhibitor 70 complexed with the NS3 protease and biological data are also discussed.
