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.

A series of P2-modified, orally active peptidic inhibitors of human neutrophil elastase (HNE) are reported. These pentafluoroethyl ketone-based inhibitors were designed using pentafluoroethyl ketone 1 as a model. Rational structural modifications were made at the P3, P2, and activating group (A(G)) portions of 1 based on structure-activity relationships (SAR) developed from in vitro (measured K(i)) data and information provided by modeling studies that docked inhibitor 1 into the active site of HNE. The modeling-based design was corroborated with X-ray crystallographic analysis of the complex between 1 and porcine pancreatic elastase (PPE) and subsequently the complex between 1 and HNE.
Rational design and synthesis of a novel, selective class of thrombin inhibitors: P1-argininal derivatives incorporating P3-P4 quaternary lactam dipeptide surrogates

SAR and molecular modeling investigations on the potent and selective thrombin inhibitor 1b (CVS 1578) and related serine protease inhibitors led to the design of series 2a-g, featuring quaternary α-amino-α-benzyl-lactam scaffolds that serve as novel P3-P4 dipeptide mimics. The design, synthesis, and biological activity of these targets an presented.
