develop novel antifungal agents, based on our previous work, a series of (2R,3R)-3-((3-substitutied-isoxazol-5-yl)methoxy)-2-(2,4-difluorophenyl)-1-(1H-1,2,4-triazol-1-yl) butan-2-ol (a1-a26) were designed and synthesized. All of the compounds exhibited good in vitro antifungal activities against eight human pathogenic fungi. Among them, compound a6 showed excellent inhibitory activity against Candida
为了开发新型的抗真菌剂,在我们之前的工作基础上,一系列的(2 R,3 R)-3-((3-取代-异恶唑-5-基)甲氧基)-2-(2,4-二氟苯基设计并合成了)-1-(1 H -1,2,4-三唑-1-基)丁-2-醇(a1 - a26)。所有这些化合物对八种人类致病真菌均表现出良好的体外抗真菌活性。其中,化合物a6对白色念珠菌和副念珠菌具有优异的抑制活性,MIC 80值为0.0313μg/ mL。此外,化合物a6,a9,a12,a13和a14对耐氟康唑的分离株表现出中等抑制活性,MIC 80值为8μg/ mL至16μg/ mL。此外,化合物a6,a12和a23表现出对CYP3A4的低抑制特性。分析了清晰的SAR,并进行了分子对接实验,以进一步研究a6与目标酶CYP51之间的关系。
