Elastatinal is a potent inhibitor of pancreatic elastase (Ki = 240 nM) that is produced by various species of Actinomycetes. [1] It more strongly inhibits pancreatic elastase versus the leukocyte-derived enzyme. [2] [3] 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.[4] It can also inhibit elastase-like protease collagenolytic protease from C. maenas digestive glands.[5]
