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.

Two series of conformationally constrained analogues of Pro-Leu-Gly-NH2 (PLG) have been synthesized.In one series of analogues, the Leu-Gly-NH2 dipeptide segment of PLG was replaced with the γ-lactam residues 3(S)- and 3(R)-amino-2-oxopyrrolidineacetamide
Protected Lactam-Bridged Dipeptides for Use as Conformational Constraints in Peptides

General methods have been devised for the synthesis of lactam-constrained dipeptide analogues having five-, six-, and seven-membered rings.Three different paths from protected chiral α-amino acids to lactams involving intramolecular alkylation, intramolecular acylation, and insertion of a one carbon unit by condensation with formaldehyde have been utilized.The first two methods produce chiral products stereospecifically, but considerable racemization occurs in the third route which leads to a 4-oxo-5-amino-1,3-thiazine (13).The products are prepared in good yield and have protecting groups making them suitable for incorporation into higher peptides by methods commonly used.
