2a4q | pdb_00002a4q
|
HCV NS3 protease with NS4a peptide and a covalently bound macrocyclic ketoamide compound.
Overview
The 17-membered phenylalanine-based macrocycle 6 was prepared starting, from 3-iodo-phenylalanine. Macrocyclization of alkene phenyl iodide 5 was, effected through a palladium-catalyzed Heck reaction. The macrocyclic, alpha-ketoamides were active inhibitors of the HCV NS3 protease, with the, C-terminal acids and amides being more potent than tert-butyl esters.
