Description |
Alvelestat (AZD9668) is an oral, highly selective inhibitor of neutrophil elastase (NE) with IC50 and Ki of 12 nM and 9.4 nM, at least 600-fold more selective over other serine proteases.
Phase 2.

Targets
|
neutrophil elastase [1] |
neutrophil elastase [1] |
9.4 nM(Ki) |
12 nM |
|
In vitro |
AZD9668 inhibits plasma NE activity in zymosan-stimulated whole blood, and also inhibits NE activity on the surface of stimulated polymorphonuclear cells and in the supernatant of primed, stimulated cells. [1]
|
In vivo |
In mice and rats, AZD9668 (p.o.) prevents human NE-induced lung injury. In a mouse model of smoke-induced airway inflammation, AZD9668 significantly reduces the number of BAL neutrophils and BAL IL-1β. In a guinea pig chronic smoke model, AZD9668 prevents airspace enlargement and small airway wall remodeling in guinea pigs in response to chronic tobacco smoke exposure. [1]
