2‐(benzo[d]thiazol‐2‐ylthio)‐1‐(3,4‐dihydroxyphenyl)ethanones was found to inhibit Pma1p, with the most potent IC50 value of 8 μm in an in vitro plasma membrane H+‐ATPase assay. These compounds were also found to strongly inhibit the action of proton pumping when Pma1p was reconstituted into liposomes. 1‐(3,4‐Dihydroxyphenyl)‐2‐((6‐(trifluoromethyl)benzo[d]thiazol‐2‐yl)thio)ethan‐1‐one (compound 38) showed
真菌质膜H + -ATPase(Pma1p)是发现新的抗真菌剂的潜在目标。令人惊讶的是,没有针对靶向Pma1p的小分子的结构-活性关系研究的报道。本文中,我们公开了一种乐高启发性的片段组装策略,用于设计,合成和发现含有3,4-二羟基苯基部分作为潜在Pma1p抑制剂的苯并[ d ]噻唑。发现一系列2-(苯并[ d ]噻唑-2-基硫基)-1-(3,4-二羟基苯基)乙酮可抑制Pma1p,在体外质膜中最有效的IC 50值为8μm高+‐ATPase分析。当Pma1p重构为脂质体时,还发现这些化合物强烈抑制质子泵浦的作用。1-(3,4-二羟基苯基)-2-((6-(三氟甲基)苯并[ d ]噻唑-2-基)硫基)乙酮-1(化合物38)对白色念珠菌和酿酒酵母(Saccharomyces cerevisiae),可以与体外抑制Pma1p的能力相关并得到证实。
