structural moiety with an n-tetradecyl side chain at C-6 has been demonstrated to be a new antifungal template. Thirty-four new synthetic analogues with modifications of the bicyclic tetrahydropyrrolopyrimidinium skeleton and the N-1 side chain have been prepared and evaluated for in vitro antifungal activities against the clinically important fungal pathogens including Cryptococcus neoformans ATCC 90113
已证明基于 6-羟基-2,3,4,6-四氢吡咯并[1,2- a ]嘧啶鎓结构部分在 C-6 处具有正十四烷基侧链,是一种新的抗真菌模板。三十四个与双环tetrahydropyrrolopyrimidinium骨架和N-1侧链的修饰新合成类似物已被制备并在体外抗真菌活性评价对临床上重要的真菌性病原体,包括新型隐球菌ATCC 90113,白色念珠菌ATCC 90028,光滑念珠菌ATCC 90030、克柔念珠菌ATCC 6258 和烟曲霉ATCC 90906。十九种化合物 ( 5 ,21 – 31、34 – 38、44和48 ) 对上述五种真菌病原体显示出抗真菌活性,最小抑制浓度 (MIC) 范围为 0.88–10 μM,并且均具有杀真菌活性,最小杀真菌浓度 (MFC) 类似于相应的 MIC 值。化合物24,36,和48是特别有效对抗隐球菌ATCC 90113具有1.0 / 1.0的MIC /
