Bacillus subtilis Zj016 fermentation broth was centrifuged at 4 ℃ and 10,000 r/min for 10 min. The supernatant was collected and clarified with 18% (NH4)2SO4. The supernatant was then concentrated by ultrafiltration using a 50,000 molecular weight ultrafiltration membrane. The concentrate was desalted using a 30,000 molecular weight ultrafiltration membrane and precipitated with 68% ethanol. The precipitate was then freeze-dried under vacuum to obtain BESTATIN HYDROCHLORIDE with an activity of 4.0 × 105 U/g. |

Bestatin HCl (65391-42-6) inhibits leucine aminopeptidase and aminopeptidases B and N. Inhibits leukotriene A4 hydrolase. Displays immunostimulant activity via activation of macrophages and T lymphocytes. Displays antitumor activity. | [Uses]
Bestatin has been used as a protease inhibitor for the purification of his-tagged Tau protein. | [Uses]
Bestatin is an inhibitor of amino peptidases and a potent, irreversible inhibitor of LTA4 hydrolase. It inhibits the amino peptidase activity of LTA4 hydrolase with a Ki value of 201 nM. It offers promise as a novel analgesic because it protects endogenous opioid peptides against degradation. It does not inhibit carboxypeptidases. | [Uses]
competitive aminopeptidase B inhibitor | [Definition]
ChEBI: Bestatin (hydrochloride) is a peptide. | [General Description]
Chemical structure: amino acid derivatives | [Biochem/physiol Actions]
A metalloprotease inhibitor selective for aminopeptidase. Bestatin is a competitive and specific inhibitor of leucine aminopeptidase, aminopeptidase B, and triamino peptidase. It inhibits aminopeptidase B at 60 nM (using arginine-β-naphthylamide as substrate) and leucine aminopeptidase at 20 nM (leucine-β-naphthylamide as substrate). It showed no inhibition of aminopeptidase A, trypsin, chymotrypsin, elastase, papain, pepsin, or themolysin. It offers promise as a novel analgesic because it protects endogenous opioid peptides against degradation. | [in vivo]
in a mouse dorsal air sac assay, oral administration of bestatin (100-200 mg/kg/day) showed a significant inhibitory activity against the melanoma cell-induced angiogenesis. bestatin also inhibited the tube-like formation of human umbilical vein endothelial cells (huvecs). furthermore, after the orthotopic implantation of b16-bl6 melanoma cells into mice, bestatin administration (50-100 mg/kg/day, i.p) reduced the number of vessels oriented towards the established primary tumor mass on the dorsal side of mice [1]. | [storage]
