target for the development of new antimicrobial agents. We have previously reported pyrimidine analogs as SecA inhibitors. Herein, we report an extension of the earlier work in the synthesis and evaluation of a series of 15 5-cyanothiouracil derivatives as SecA inhibitors. All the compounds have been evaluated for their inhibition of SecA ATPase (EcSecAN68) and for their antimicrobial activity against
SecA,细菌Sec依赖性分泌途径的关键组成部分,是开发新型抗菌剂的有吸引力的目标。我们之前已经报道了
嘧啶类似物作为SecA
抑制剂。在本文中,我们报告了早期合成合成和评估一系列15种5-
氰基
硫尿
嘧啶衍
生物作为SecA
抑制剂的工作的扩展。已经评估了所有化合物对SecA
ATPase(EcSecAN68)的抑制作用以及对大肠杆菌NR698(漏泄突变体)和
炭疽芽孢杆菌斯特恩(Bacillus anthracis Sterne )的抗菌活性。当对EcSecAN68进行测试时,十二种化合物的IC 50小于6.3μM。在针对大肠杆菌的抗菌研究中NR698中,有6种化合物的MIC小于12.5μM,其中3种小于6.3μM。对抗
炭疽杆菌斯特恩,三种化合物的MIC均小于6.3μM。
