  Halothiophene benzimidazoles as P1 surrogates of inhibitors of blood coagulation factor Xa

  摘要：

  Neutral weak halothiophene benzimidazole inhibitors of the serine protease factor Xa were identified via screening of a compound library. The X-ray crystal structure of representative 3a bound to human fXa confirmed the S1 binding mode. Starting from 3a a series of halothiophene benzimidazoles was synthesized and investigated for their factor Xa inhibitory activity. This led to potent and selective achiral inhibitors against fXa such as compounds 9k and 9w. (C) 2004 Elsevier Ltd. All rights reserved.
