title: Design, synthesis and structure-activity relationship of a series of arginine aldehyde factor Xa inhibitors. Part 1: structures based on the (D)-Arg-Gly-Arg tripeptide sequence.
abstract: A series of arginine aldehyde inhibitors was designed as transition state (TS) analogues based on the known factor Xa specific substrate Cbz-D-Arg-Gly-Arg-pNA. BnSO2-(D)Arg-Gly-Arg-H (20) was found to be the most potent and selective inhibitor of factor Xa and prothrombinase activity in this series.
