Thioetherhydroxyethylsulfonamide derivatives were synthesized and evaluated for their in vitro antibacterial activity against Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (ATCC 27853) and Staphylococcus aureus (ATCC 25923). Results have shown that compounds 8c and 9e display potent activity (MIC = 0.125 µg/mL) against E. coli when compared with the standard drug sulfamethoxazole (SMZ, MIC < 0.5 µg/mL) for this same strain. All the new compounds were fully identified and characterized by NMR (1H and 13C) and X-ray crystallography (for compound 8c). This class of compounds can be considered as a good starting point for the development of new lead molecules in the fight against multi-drug bacterial resistance.
合成了噻噁唑羟乙基磺酰胺衍生物,并评估其对大肠杆菌(ATCC 25922)、铜绿假单胞菌(ATCC 27853)和金黄色葡萄球菌(ATCC 25923)的体外抗菌活性。结果显示,化合物8c和9e对大肠杆菌的活性强劲(MIC = 0.125 µg/mL),相比之下,标准药物磺胺甲恶唑(SMZ,MIC < 0.5 µg/mL)对该菌株的效果也相当。所有新化合物均通过NMR(1H和13C)和X射线晶体学(针对化合物8c)进行了全面的鉴定和表征。这类化合物可以被视为在抗击多重耐药细菌方面开发新靶分子的良好起点。
