==Overview==
==Overview==
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 (AG) portions of 1 based on structure-activity, relationships (SAR) developed from in vitro (measured Ki) 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.
