Abstract

Evaluation of a series of MetAP inhibitors in an in vitro enzyme activity assay led to the first identification of potent molecules that show significant growth inhibition against Burkholderia pseudomallei. Nitroxoline analogs show excellent inhibition potency in the BpMetAP1 enzyme activity assay with the lowest IC of 30 nM, and inhibit the growth of B. pseudomallei and B. thailandensis at concentrations ≥ 31 μM.

摘要

在体外酶活性测定中对一系列甲硫氨酸氨肽酶(MetAP)抑制剂进行评估,首次鉴定出了对类鼻疽伯克霍尔德菌具有显著生长抑制作用的强效分子。硝氧喹啉类似物在BpMetAP1酶活性测定中显示出优异的抑制效力,最低半数抑制浓度(IC)为30 nM,并在浓度≥31 μM时抑制类鼻疽伯克霍尔德菌和泰国伯克霍尔德菌的生长。
