6.25 μM). A common structural feature in most active compounds was the presence of a 3,5-bis-trifluoromethyl phenyl ring at the thiourea function. In addition, the ability of the compounds to inhibit production of nitric oxide (NO) was examined in RAW 264.7 murine macrophages, highlighting the potential of piperazine-derived thioureas as promising scaffolds for the design of new combined anti-bact
鲍曼不动杆菌是医院单位中最重要的耐多药微生物之一。它对多种抗生素具有抗性,因此有必要开发新的治疗策略。这项研究的目的是评估一组哌嗪衍生的硫脲对13种对大肠菌素耐药的鲍曼不动杆菌的临床菌株的抗菌活性。鉴定出六种衍生物可抑制鲍曼不动杆菌46%的细菌生长低摩尔浓度(最小抑制浓度从1.56至6.25μM)的菌株。大多数活性化合物的常见结构特征是在硫脲官能团处存在3,5-双三氟甲基苯环。此外,在RAW 264.7鼠巨噬细胞中检测了该化合物抑制一氧化氮(NO)产生的能力,突出了哌嗪衍生的硫脲作为设计新型抗菌/消炎药组合的有希望的支架的潜力。
