Substituted acrylamides were used as templates that bridge P1 and P4 binding elements, resulting in a series of potent sub-nanomolar) and selective factor Xa inhibitors. In this template, cis-geometry of P1 and P4 ligands is highly preferred. SAR on the substituting groups, as well as on modification of P1 and P4 moieties is described. Compounds in this series show good in vivo efficacy in animal models. (C) 2002 Elsevier Science Ltd. All rights reserved.

A facile and high efficiency photo-enzyme catalysis system for the E to Z isomerization of alkenes has been developed. Using a photo-enzyme hybrid system with good versatility, 43 Z-configurations of α, β-unsaturated esters and stilbenes were synthesized in good yields, in which the highest Z/E ratio was 91:9. This photo-enzyme catalysis system has wide substrate range, mild reaction conditions and
