A series of 1-(1H-1,2,4-triazol-1-yl)-2-(2,4-difluorophenyl)-3-[N-propyl-N-((1-substituted-1H-1,2,3-triazol-4-yl)methyl)amino]-2-propanols which are analogues of fluconazole, have been designed and synthesized on the basis of computational docking experiments to the active site of the cytochrome P450 14α-demethylase (CYP51). Their structures were characterized by 1H NMR, 13C NMR and HR ESI MS. The MIC80 values indicate that the target compounds 1a–o showed higher activities against nearly all the fungi tested to some extent except against A. fum. and T. rub. All of the target compounds exhibited higher activities against C. alb. SC5314 and C. alb. Y0109 than all of the six positive controls.
一系列1-(1H-1,2,4-三唑-1-基)-2-(2,4-二氟苯基)-3-[N-丙基-N-((1-取代-1H-1,2,3-三唑-4-基)甲基)氨基]-2-丙醇作为氟康唑的类似物,基于对细胞色素P450 14α-去甲基酶 (CYP51) 活性位点的计算对接实验进行了设计和合成。其结构通过1H NMR、13C NMR和高分辨率电喷雾质谱(HR ESI MS)进行表征。MIC80值表明,靶向化合物1a–o对几乎所有测试的真菌显示出较高的活性,除了对烟霉菌(A. fum.)和金黄地霉(T. rub.)外。所有靶向化合物对C. alb. SC5314和C. alb. Y0109的活性均高于所有六个阳性对照。
