more potent with MIC values of 1 μg/mL against the MRSA (3167 and 3506) strains than those of gatifloxacin, oxacillin, and norfloxacin. Compared to the previously reported rhodanine derivatives, 2-thioxothiazolidin-4-one derivatives exhibited an inhibition against Gram-negative strains due to the introduction of a 1,3,4-oxadiazole moiety, among which compounds 3 showed moderate activities against the
设计并合成了两种新型的3-((5-苯基-1,3,4-恶二唑-2-基)甲基)-2-硫代噻唑啉酮-4-酮衍生物,并对其抗菌活性进行了评价。这些化合物对革兰氏阳性和革兰氏阴性细菌均具有广谱抑制活性,其最小抑菌浓度(MIC)值在1–64μg/ mL的范围内。化合物6c的抗MRSA(3167和3506)菌株的MIC值为1μg/ mL,比加替沙星,奥沙西林和诺氟沙星的活性更强。与以前报道的若丹宁衍生物相比,由于引入了1,3,4-恶二唑部分,因此2-thioxothiazolidin-4-one衍生物对革兰氏阴性菌株具有抑制作用,其中化合物3对革兰氏阴性细菌(埃希氏菌属1924年)表现出中等活性,MIC值为16μg/ mL。
