Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC50/Ki
neutrophil elastase [1]
(Cell-free assay)
9.4 nM(Ki)
neutrophil elastase [1]
(Cell-free assay)
12 nM
In vitro
Alvelestat (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, Alvelestat (AZD9668) (p.o.) prevents human NE-induced lung injury. In a mouse model of smoke-induced airway inflammation, it significantly reduces the number of BAL neutrophils and BAL IL-1β. In a guinea pig chronic smoke model, this compound prevents airspace enlargement and small airway wall remodeling in guinea pigs in response to chronic tobacco smoke exposure. [1]
