A series of new triazole derivatives were designed and synthesized on the basis of the active site of lanosterol 14α‐demethylase from Candida albicans (CACYP51). 2‐(2,4‐Difluorophenyl)‐3‐(methyl‐(3‐phenoxyalkyl)amino)‐1‐(1H‐1,2,4‐triazol‐1‐yl)propan‐2‐ols show excellent in‐vitro activity against most of the tested pathogenic fungi. The MIC80 value of compound 8a against Candida albicans is 0.01 μM
以白色念珠菌羊毛甾醇14α-脱甲基酶(CACYP51)的活性位点为基础,设计合成了一系列新的三唑衍生物。2-(2,4-二氟苯基)-3-(甲基-(3-苯氧基烷基)氨基)-1-(1H-1,2,4-三唑-1-基)丙-2-醇表现出优异的体外对大多数测试的病原真菌的活性。化合物 8a 对白色念珠菌的 MIC80 值为 0.01 μM,为进一步结构优化提供了良好的起始模板。通过灵活的分子对接研究了设计化合物的结合模式。这些化合物通过疏水、范德华力和氢键相互作用与 CACYP51 相互作用。
