Highly efficacious factor Xa inhibitors containing α-substituted phenylcycloalkyl P4 moieties
摘要:
We previously disclosed a series of highly potent FXa inhibitors bearing alpha-substituted ((CH2NRR2)-R-1) phenylcyclopropyl P4 moieties in the pyrazolodihydropyridone core system. Herein, we describe our continuous SAR efforts in this series. Effects of the C-3 substitution of the pyrazolodihydropyridone core and the alpha-substitution (R group) of the cyclopropyl ring on FXa binding affinity (FXa K-i), human plasma anticoagulant activity (PT EC2x) and permeability are discussed. A set of compounds obtained from optimization of the R group and the C-3 substituent were orally bioavailable in dogs. Furthermore, representative compounds were highly efficacious in the rabbit arterio-venous shunt thrombosis model (EC(50)s = 29-81 nM). (C) 2008 Elsevier Ltd. All rights reserved.
