Design, synthesis, and in vitro biological activity of benzimidazole based factor Xa inhibitors
摘要:
Inhibitors based on the benzimidazole scaffold showed subnanomolar potency against Factor Xa with 500-1000-fold selectivity against thrombin and 50-100-fold selectivity against trypsin. The 2-substituent on the benzimidazole ring had a strong impact on the FXa inhibitory activity. Crystallography studies suggest that the 2-substituent may have a conformational effect favoring the extended binding conformation. (C) 2000 Elsevier Science Ltd. All rights reserved.

Optimization of the benzimidazole-based fXa inhibitors for selectivity versus thrombin and trypsin was achieved by substitution on the benzimidazole ring and replacement of the naphthylamidine group. Substitution of a nitro group at the 4-position on the benzimidazole improves both potency against fXa and selectivity versus thrombin. Alternatively, replacement of the naphthylamidine with either a biphenylamidine or propenylbenzamidine not only improves fXa potency and selectivity versus thrombin, but selectivity versus trypsin as well.
