A new class of inhibitors of human leucocyte elastase

AbstractStudies of the inhibition of elastases at a molecular level have resulted in the identification of protected dipeptides which are reversible and highly specific inhibitors of human leucocyte elastase (HLE). These have been further developed by increasing their hydrophilicity and potency to give a new family of elastase inhibitors, typicaly Nα-(1-adamantanesulphonyl)-Nϵ-(4-carboxybenzoyl)-L-lysyl-L-alanyl-L-valinal. These compounds are active in pharmacological models designed to detect compounds of potential therapeutic value in the treatment of emphysema
