Clear solution
5%DMSO Corn oil
2.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 50 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Alvelestat (AZD9668, Avelestat) 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]
(Cell-free assay)		 neutrophil elastase [1]
(Cell-free assay)
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]

Protocol (from reference)

  • Dosages

    ~10 mg/kg (mice); ~20 mg/kg (rats); ~100 mg/kg (pigs)

  • Administration

    p.o.
