title: Novel 2-oxoimidazolidine-4-carboxylic acid derivatives as hepatitis C virus NS3-4A serine protease inhibitors: synthesis, activity, and X-ray crystal structure of an enzyme inhibitor complex.
abstract: Synthesis and HCV NS3 serine protease inhibitory activity of some novel 2-oxoimidazolidine-4-carboxylic acid derivatives are reported. Inhibitors derived from this new P2 core exhibited activity in the low microM range. X-ray structure of an inhibitor, 15c bound to the protease is presented.
