| Hazard Information | Back Directory | [Description]
Ketomethylenebestatin is a carba-analogue of the aminopeptidase (AP) inhibitor bestatin. This synthesis was carried out by a malonic ester alkylation with the suitably protected halomethyl ketone of (2S,3R)-AHPBA*), followed by a second alkylation with isobutyl bromide of the resulting 4-ketodiester, and subsequent decarboxylation and deprotection. Ketomethylenebestatin is 10 fold less effective as inhibitor of aminopeptidases than bestatin. | [Uses]
Ketomethylenebestatin is an aminopeptidase (AP) inhibitor and an analog of the natural aminopeptidase inhibitor Bestatin (HY-B0134) with IC50 of 56 μM, 752 μM and 0.39 μM for AP-B, AP-M and Leu-AP, respectively[1]. | [References]
