biphenyl-benzamides as FtsZ inhibitors has been rationally designed, synthesized and evaluated for their antibacterial activities against various Gram-positive bacteria strains. In particular, the most promising compound 30 exhibited excellent antibacterial activities, especially against four different Bacillus subtilis strains, with an MIC range of 0.008 μg/mL to 0.063 μg/mL. Moreover, compound 30 also showed
抗生素耐药性的迅速出现已成为对公众健康的普遍威胁,因此迫切需要开发具有新作用机制的新型抗菌剂。针对细胞骨架细胞分裂蛋白丝状温度敏感突变体 Z (FtsZ) 已被证实是一种有效且有前景的抗菌药物发现方法。本研究合理设计、合成了一系列新型联苯-苯甲酰胺作为 FtsZ 抑制剂,并评估了它们对各种革兰氏阳性菌的抗菌活性。特别是,最有前途的化合物30表现出优异的抗菌活性,尤其是对四种不同的枯草芽孢杆菌菌株,MIC 范围为 0.008 μg/mL 至 0.063 μg/mL。此外,化合物30还表现出良好的药学性质,具有低细胞毒性(CC 50 > 20 μg/mL)、优异的人体代谢稳定性(T 1/2 = 111.98 min)、适中的药代动力学(T 1/2 = 2.26 h,F = 61.2) %)和体内功效,这可以被确定为一种有前途的 FtsZ 抑制剂,值得进一步分析。
