Design of novel HIV-1 protease inhibitors incorporating isophthalamide-derived P2-P3 ligands: Synthesis, biological evaluation and X-ray structural studies of inhibitor-HIV-1 protease complex
摘要:
Based upon molecular insights from the X-ray structures of inhibitor-bound HIV-1 protease complexes, we have designed a series of isophthalamide-derived inhibitors incorporating substituted pyrrolidines, piperidines and thiazolidines as P2-P3 ligands for specific interactions in the S2-S3 extended site. Compound 4b has shown an enzyme K-i of 0.025 nM and antiviral IC50 of 69 nM. An X-ray crystal structure of inhibitor 4b-HIV-1 protease complex was determined at 1.33 angstrom resolution. We have also determined X-ray structure of 3b-bound HIV-1 protease at 1.27 angstrom resolution. These structures revealed important molecular insight into the inhibitor-HIV-1 protease interactions in the active site. (C) 2017 Elsevier Ltd. All rights reserved.

synthesis and biological evaluation of a series of novel HIV-1proteaseinhibitors bearing isophthalamide derivatives as the P2–P3 ligands. We have investigated a range of acyclic and heterocyclic amides as the extended P2–P3 ligands. These inhibitors displayed good to excellent HIV-1protease inhibitory activity. Also, a number of inhibitors showed very good antiviral activity in MT cells. Compound
