ABSTRACT
|
|
|
|
| |
|
|
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.

The most recent references are shown first.
Citation data come partly from CiteXplore and partly
from an automated harvesting procedure. Note that this is likely to be
only a partial list as not all journals are covered by
either method. However, we are continually building up the citation data
so more and more references will be included with time.
Where a reference describes a PDB structure, the PDB
code is
shown on the right.
