Description

General description

A benzoxazinone compound that acts as a potent inhibitor of human leukocyte elastase (IC₅₀ = 29.5 nM), likely by covalently modifying active site serine via a Michael addition-elimination reaction. Shown to inhibit medium elastase activity (IC₅₀ = 80.8 nM), but not O₂^•- generation, in fLMP (Cat. No. 05-22-2500)-stimulated primary human neutrophil cultures. Reported to reduce neutrophil infiltration in lung after hemorrhagic shock in rats in vivo (1 mg/kg, i.v.) as assessed by increase in lung wet/dry ratio (0.75- vs. 1.23-fold increase, respectively, with or without treatment) and MPO activity (1.08- vs. 3.72-fold increase, respectively, with or without treatment).
