Wild-type HIV-1 Protease in complex with potent inhibitor GRL06579
Overview
Structure-based design and synthesis of novel HIV protease inhibitors are, described. The inhibitors are designed specifically to interact with the, backbone of HIV protease active site to combat drug resistance. Inhibitor, 3 has exhibited exceedingly potent enzyme inhibitory and antiviral, potency. Furthermore, this inhibitor maintains impressive potency against, a wide spectrum of HIV including a variety of multi-PI-resistant clinical, strains. The inhibitors incorporated a stereochemically defined, 5-hexahydrocyclopenta[b]furanyl urethane as the P2-ligand into the, (R)-(hydroxyethylamino)sulfonamide isostere. Optically active, (3aS,5R,6aR)-5-hydroxy-hexahydrocyclopenta[b]furan was prepared by an, enzymatic asymmetrization of meso-diacetate with acetyl cholinesterase, radical cyclization, and Lewis acid-catalyzed anomeric reduction as the, key steps. A protein-ligand X-ray crystal structure of inhibitor 3-bound, HIV-1 protease (1.35 A resolution) revealed extensive interactions in the, HIV protease active site including strong hydrogen bonding interactions, with the backbone. This design strategy may lead to novel inhibitors that, can combat drug resistance.
