Novel, potent phenethylamide inhibitors of the hepatitis C virus (HCV) NS3 protease: probing the role of P2 aryloxyprolines with hybrid structures
摘要:
Synthesis of hybrid HCV NS3 protease/NS4A inhibitors having the 4,4-difluoroaminobutyric acid (difluoroAbu) phenethylamides as P1-P1' and quinolyloxyprolines as P2 fragments led to 7 (IC50 54 nM). Molecular modelling suggests that this potent tripeptide inhibitor utilizes interactions in the S1', S1, S2, S3 and S4 sites of the protease. (C) 2003 Elsevier Ltd. All rights reserved.
SAR and pharmacokinetic studies on phenethylamide inhibitors of the hepatitis C virus NS3/NS4A serine protease
摘要:
SAR on the phenethylamide I (K-i 1.2 muM) in the P2- and the V-position led to potent inhibitors, one of which showed good exposure and low clearance when administered intramuscularly to rat. (C) 2004 Elsevier Ltd. All rights reserved.
