community-acquired infections, with drug-resistant strains being responsible for tens of thousands of deaths per year. S. aureus sortase A inhibitors are designed to interfere with virulence determinants. We have identified disulfanylbenzamides as a new class of potent inhibitors against sortase A that act by covalent modification of the active-site cysteine. A broad series of derivatives were synthesized to
金黄色葡萄球菌是医院和社区获得性感染的最常见原因之一,耐药菌株每年导致数万人死亡。金黄色葡萄球菌分选酶 A 抑制剂旨在干扰毒力决定因素。我们已经确定二硫烷基苯甲酰胺是一类新型有效的分选酶 A 抑制剂,通过活性位点半胱氨酸的共价修饰发挥作用。合成了一系列广泛的衍生物来推导构效关系(SAR)。体外和计算机方法使实验观察到的结合亲和力和选择性合理化。研究发现,最活跃的化合物具有个位数的微摩尔 Ki 值,在 10 μM 的有效抑制剂浓度下,金黄色葡萄球菌纤维蛋白原附着量减少高达 66%。这种新分子类别表现出最小的细胞毒性、较低的细菌生长抑制和分选酶介导的金黄色葡萄球菌细胞粘附受损。
