Novel triazole compounds with a dioxane ring were synthesized. Condensation of the diol precursor 10 with various aromatic aldehydes 11-13 under acidic conditions afforded a series of dioxane-triazole compounds 14-16. The antifungal activities of the compounds 14-16 were evaluated in vivo in mice infection models against Candida and Aspergillus species. High activities were seen for the derivatives with one or two double bond(s) and an aromatic ring substituted with an electron-withdrawing group in th side chain. Among the derivatives, R-102557 (16R : Ar=4-(2, 2, 3, 3)-tetrafluoropropoxy)phenyl)showed excellent in vivo activities against Candida, As-pergillus and Cryptococcus species. It also showed high tolerance in a preliminary toxicity study in rats.
具有二噁烷环的新型三唑化合物被合成。在酸性条件下,二醇前体10与各种芳香醛11-13缩合,得到了一系列二噁烷-三唑化合物14-16。这些化合物14-16的抗真菌活性通过在小鼠感染模型中对白色念珠菌和曲霉菌的评估进行了体内评价。含有单个或两个双键且侧链上带有吸电子基团的芳环衍生物表现出较高的活性。在这些衍生物中,R-102557(16R:Ar=4-(2,2,3,3-四氟丙氧基)苯基)对白色念珠菌、曲霉菌和隐球菌属表现出极佳的体内活性。在大鼠的初步毒性研究中也显示出高度耐受性。
