A series of fluconazole analogues containing 1,2,3-triazole fragment have been designed and synthesized on the basis of the active site of the cytochrome P450 14α-demethylase (CYP51). Their structures were characterized by 1H NMR, 13C NMR and LC–MS. The MIC80 values indicate that the target compounds 1a–r showed higher activities against nearly all the fungi tested to some extent except against Aspergillus fumigatus. Compounds 1c, e, f, l and p showed 128 times higher activity (with the MIC80 value of 0.0039 mg/mL) than that of fluconazole against Candida albicans and also showed higher activity than that of the other positive controls.
基于细胞色素P450 14α-去甲基化酶(CYP51)的活性位点,设计并合成了一系列含有1,2,3-三唑片段的氟康唑类似物。通过1H NMR、13C NMR和LC-MS对其结构进行了表征。MIC80值表明,目标化合物1a-r对几乎所有测试的真菌都显示出更高的活性,仅对烟曲霉(Aspergillus fumigatus)活性有限。化合物1c、e、f、l和p对白色念珠菌(Candida albicans)的活性比氟康唑高出128倍(MIC80值为0.0039 mg/mL),并且其活性也优于其他阳性对照药物。
