their antifungal activities in vitro by evaluation of broth dilution MIC values against three species of fungi and the inhibitory effect on pseudomycelium of Candida albicans, and they were examined for oral efficacy in vivo against subacute systemic candidiasis in mice and superficial dermatophytosis in guinea pigs. Compounds 2, 12, 38, 39, and 92 exhibited strong oral antifungal activity. An asymmetric
为了找到口服活性抗真菌剂,合成了新的咪唑基-和1,2,4-三唑基丙醇酮I和相关化合物II-IV。化合物I衍生自酮V(方法A),α-二酮IX(方法B),α-羟基酮X(方法C),α-氯酮XII(方法D)和烯酮VI(方法E)。使用N,N'-羰基二咪唑,亚硫酰氯,N,N'-(硫代羰基)二咪唑,溴氯甲烷,2,2-二甲氧基丙烷和环己酮将由I与NaBH4合成的二元醇II环化为五元环状化合物III。二甲基缩酮。通过Grignard反应(方法F),X的羟甲基化(方法G)和酮XXI与1-[((三甲基甲硅烷基)甲基] -1,2,4-三唑(方法H)的反应,由I合成二元醇IV。通过评价肉汤对三种真菌的稀释MIC值和对白色念珠菌假菌丝体的抑制作用,检查了化合物I-IV的体外抗真菌活性,并在小鼠和小鼠体内检查了它们对亚急性系统性念珠菌病的口服药效。豚鼠浅表皮肤癣菌病。化合物2、12、38、39和92表现出较强的口服抗真
