In an effort to find potent antifungal agents, optically active sulfur-containing triazole derivatives, sulfides (3) and sulfonamides (4), were prepared and evaluated for antifungal activity against Candida albicans in vitro and in vivo. The sulfides (3) were prepared by the reaction of (2R, 3R)-2-(2, 4-difluorophenyl)-3-mercapto-1-(1H, 1, 2, 4-triazol-1-yl)-2-butanol (1) with various heteroarylmethyl chlorides in the presence of sodium methoxide. The sulfonamides (4) were synthesized starting from the disulfide (15) in three steps including oxidation of the corresponding sulfenamides (17). Some of the sulfur-containing triazole derivatives (3, 4) showed strong protective effects against candidosis in mice.
为了寻找强效的抗真菌剂,制备并评估了对光学活性含硫三唑衍生物,硫醚(3)和磺胺(4)对白色念珠菌的体外和体内抗真菌活性。硫醚(3)是通过(2R,3R)-2-(2,4-二氟苯基)-3-巯基-1-(1H,1,2,4-三唑-1-基)-2-丁醇(1)与各种杂芳基氯甲烷在甲醇钠存在下反应制备的。磺胺(4)是从二硫化物(15)开始以三个步骤合成的,包括相应亚磺酰胺(17)的氧化。一些含硫三唑衍生物(3,4)显示出对小鼠念珠菌病的强烈保护作用。
