摘要:
Homophthalimides 2a and 3a were found to be inhibitors of Rhinovirus 3C protease through a blind screening effort. SAR studies resulted in compound 3g, which exhibited improved enzyme inhibition, in addition to whole cell antiviral activity. Molecular modeling studies suggest a preferred enzyme/inhibitor interaction, and LC/MS experiments confirmed tight/covalent binding of 3g to the enzyme. (C) 1997 Elsevier Science Ltd.
