Azetidines and spiro azetidines as novel P2 units in hepatitis C virus NS3 protease inhibitors
摘要:
Herein, we report the synthesis and structure-activity relationship studies of new analogs of boceprevir 1 and telaprevir 2. Introduction of azetidine and spiroazetidines as a P2 substituent that replaced the pyrrolidine moiety of 1 and 2 led to the discovery of a potent hepatitis C protease inhibitor 37c (EC50 = 0.8 mu M).
