Several 6-substituted tetrahydrocarbazole derivatives were designed, synthesized and evaluated for the antibacterial activities against Staphylococcus aureus Newman strain. Subsequently, 2,4-diaminopyrimidine scaffold was merged with the tetrahydrocarbazole unit to generate a series of novel hybrid derivatives and the antibacterial activities were also investigated. Among these novel hybrids, compound 12c showed the most potent activity with a MIC of 0.39-0.78 μg/mL against S. aureus Newman and Escherichia coli AB1157 strain. In addition, compound 12c exhibited low MIC values against a panel of multidrug-resistant strains of S. aureus.
设计、合成了几种 6-取代四氢咔唑衍生物,并评价了它们对金黄色葡萄球菌 Newman 株的抗菌活性。随后,将 2,4-二氨基嘧啶支架与四氢咔唑单元融合,生成了一系列新型杂合衍生物,并对其抗菌活性进行了研究。在这些新型杂合物中,化合物 12c 对金黄色葡萄球菌 Newman 和大肠杆菌 AB1157 菌株表现出最强的活性,MIC 为 0.39-0.78μg/mL。此外,化合物 12c 对一组耐多药的金黄色葡萄球菌菌株表现出较低的 MIC 值。
