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.

Evolution of P1-argininal inhibitor prototypes led to a series of non-covalent P3-7-membered lactam inhibitors 1a-w, featuring novel peptidomimetic units that probe each of the S1, S2, and S3 specificity pockets of thrombin. Rigid P1-arginine surrogates possessing a wide range of basicity (calcd pKa's～neutral-14) were surveyed. The design, synthesis, and biological activity of these targets are presented.
