bacterial pathogenicity, a set of novel imidazolidine‐2,4‐dione and 2‐thioxoimidazolidin‐4‐one derivatives was synthesized and evaluated as inhibitors of bacterial virulence. The new compounds were characterized and screened for their effects on the expression of virulence factors of Pseudomonas aeruginosa, including protease, hemolysin, and pyocyanin. Imidazolidine‐2,4‐diones 4c, 4j, and 12a showed complete
为了对抗细菌致病性,合成了一组新型咪唑烷-2,4-二酮和 2-硫代咪唑烷-4-one 衍生物,并将其作为细菌毒力的抑制剂进行评估。对新化合物进行了表征并筛选了它们对铜绿假单胞菌毒力因子(包括蛋白酶、溶血素和绿脓素)表达的影响。咪唑烷-2,4-二酮 4c、4j 和 12a 显示出对蛋白酶的完全抑制,并且它们在 1/4 MIC(1/4 最小抑制浓度;1、0.5 和 0.5 mg)下几乎完全抑制了溶血素的产生/ml,分别)。2-Thiooxoimidazolidin-4-one 衍生物 7a 在 1 mg/ml (1/4 MIC) 时对绿脓菌素的产生表现出最好的抑制活性 (96.4%)。
