Bestatin

Bestatin is an aminopeptidase inhibitor originally isolated from S. olivoreticuli. It inhibits aminopeptidase B (IC50 = 0.05 µg/ml), aminopeptidase N (IC50 = 16.9 µM), leucine aminopeptidase (IC50 = 0.01 µg/ml), and the aminopeptidase activity of leukotriene A4 (LTA4) hydrolase (Kapp = 172 nM). It is selective for these aminopeptidases over aminopeptidase A, trypsin, chymotrypsin, elastase, papain, pepsin, and thermolysin. Bestatin inhibits the production of LTB4 (Item No. 20110) in erythrocytes when used at a concentration of 70 µM. It increases the expression of Akt, inhibits proliferation,...
