摘要: 根据三唑类抗真菌药物作用靶酶-羊毛甾醇14α-去甲基化酶的三维晶体结构和药物与酶活性位点的对接结果,设计合成了111-(1H-1,2,4-三唑-1-)-2-(2,4-二氟苯基)-3-(N-甲基-N取代苄基氨基)-2-丙醇化合物.11个目标化合物均系首次报道.体外抗真菌活性试验结果表明,所有目标化合物对七种致病真菌都有不同程度的抗真菌活性,而且都比氟康唑的体外抗真菌活性好.化合物11的抗菌谱最广,抗真菌活性最高,对新型隐球菌、白色念珠菌、羊毛状小孢子菌和红色毛癣菌的抗菌活性比酮康唑高,有进一步开发的价值.化合物3,4,10也表现出较高的抗真菌活性.

Abstract: Eleven 1-(1H-1,2,4-triazole)-2-(2,4-diflurophenyl)-3-(N-methyl-N-substituted benzylamino)-2-propanols were designed and synthesized, on the basis of the crystal structure of P450 cytochrome 14α-sterol demethylase(CYP51) and the docking results of inhibitors to the active site of the enzyme. All title compounds were first by reported. Results of preliminary biological tests showed that most of title compounds exhibited activity against the seven common pathogenic fungi. Compound 11 showed best antifungal activity with broad antifungal spectrum and proved to be more active against Cryptococcus neoformans, Candida albicans, Microsporum lanosum and Trichophyton rubrum than ketoconazole. Compounds 3, 10 and 4 also had high activities.
