neoformans var. grubii with MIC values ranging from 4 to 16 μg/mL. Furthermore, they were not cytotoxic against red blood cells and human embryonic kidney cells at concentration up to 32 μg/mL. The study was expanded to forecast the mechanism of action of the prepared compounds and determine sterol quantitation method (SQM) by spectrophotometric assay. On the other hand, compound 4e showed the highest
在此,新的三个系列的苯并咪唑骨架轴承腙,1,2,4-三唑和1,3,4-恶二唑基部分1 - 3,图4a-j中,图6A-C和7周的衍生物设计,合成并评价了它们的抗微生物活动。使用不同的光谱技术(例如IR,1 H NMR,13 C NMR和元素分析)指定制备的化合物的结构。化合物3,图4a,图4e和4f中显示出显着的抗真菌活性的白色念珠菌和隐球菌变种。古比MIC值为4至16μg/ mL。此外,它们在浓度高达32μg/ mL时对红细胞和人胚肾细胞没有细胞毒性。扩大了研究范围,以预测所制备化合物的作用机理,并通过分光光度法测定固醇定量方法(SQM)。在另一方面,化合物4e中显示对羊毛甾醇14α脱甲基酶(CYP51)与IC的最高抑制活性50值= 0.19微克/毫升相比氟康唑作为参考IC 50值= 0.62微克/毫升。同样,化合物4d和4f表现出中等至中等的抗菌活性。而且,活性靶化合物4e的分子对接羊毛
