Elastatinal is a potent inhibitor of pancreatic elastase (K_i = 240 nM) that is produced by various species of Actinomycetes. It more strongly inhibits pancreatic elastase versus the leukocyte-derived enzyme. Elastatinal reduces electrophoretic mobilities of 2A proteinases from poliovirus and human rhinovirus 14 in a dose-dependent manner, indicating substrate recognition by 2A proteinases is similar to that of pancreatic elastases. It can also inhibit elastase-like protease collagenolytic protease from C. maenas digestive glands.

Elastatinal is an elastase inhibitor.

Potent, irreversible elastase inhibitor. Elastatinal is a much stronger inhibitor of elastase from pancreas than from leucocytes.
