The effect of a peptide aldehyde reversible inhibitor of elastase on a human leucocyte elastase-induced model of emphysema in the hamster. [Journal Article]
Eur J Respir Dis 1987 Nov; 71(5):472-8.
The peptide aldehyde Ro 31-3537, N alpha-(1-adamantanesulphonyl)-N epsilon-(4-carboxybenzoyl)-L-lysyl-L-alanyl-L- valinal, is a reversible competitive, hydrophilic, specific inhibitor of elastase. Its Ki against human leucocyte elastase is 6 x 10(-8) M. The effect of this compound has been studied on a model of emphysema in the hamster induced by multiple sequential intratracheal doses of human leucocyte elastase. Concomitant intratracheal dosing of 200 micrograms of inhibitor with the enzyme significantly reduces lung damage as measured by quasi-static lung compliance and by histological assessment of the emphysema.
