A series of novel transition state factor Xa inhibitors containing a variety, of lactam ring systems as central templates was synthesized in an expedient manner and allowed for a great deal of structural variability. Among them. the piperazinone-based inhibitors were found to be not only active against factor Xa but also selective over thrombin. Optimization of the P4 moiety yielded several potent compounds with IC50 below 1 nM against factor Xa. (C) 2003 Elsevier Science Ltd. All rights reserved.
