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 in erythrocytes when used at a concentration of 70 μM. It increases the expression of Akt, inhibits proliferation, migration, and invasion, and induces autophagy and apoptosis in 5637 bladder cancer cells. Bestatin (5 and 15 mg/kg) decreases serum levels of LTB4 and reduces tumor growth in a patient-derived xenograft (PDX) mouse model of colorectal cancer.
