Elastatinal is a potent and competitive inhibitor of elastase, with a Ki of 0.21 μM. Elastatinal more potently inhibits pancreatic elastase versus leucocyte elastase. Elastatinal shows no activity on human leucocyte chymotrypsin-like protease[1][2][3][4].

In Vitro	Elastatinal inhibits the binding of acetyl-alanyl-alanyl-alanine pnitroanilide and acetyl-alanyl-alanyl-alanine methyl ester to elastase, with Kis of 0.24 μM and 0.21 μM, respectively[1]. Elastatinal (5-20 μM) suppresses the enhanced osteoclast differentiation by neutrophils[3].
