A series of halogenated 2-arylimino-3-ary-thiazolidine-4-ones containing (5-furan-2-yl)-benzoic acid or (5-thiophene-2-yl)-benzoic acid fragments were synthesized, and evaluated in vitro for their antibacterial activity, antibiofilm activity, erythrocyte hemolysis and cytotoxicity. Compounds (7c, 7f, 7i, 7n and 7p) exhibited excellent potency in inhibiting the growth of Staphylococcus epidermidis ATCC35984 (minimal inhibitory concentration (MIC): 0.8 μg/mL). The five compounds also presented promising antibiofilm activity against S. epidermidis ATCC35984 and none of them showed obvious hemolytic activity and cytotoxicity. Further antibacterial effects of the selected five compounds (7c, 7f, 7i, 7n and 7p) against clinical isolates (methicillin-resistant Staphylococcus epidermidis and methicillin-resistant Staphylococcus aureus) were investigated in comparison with methicillin and ampicillin.7p showed the most potent antibacterial activities among the synthesized compounds.
合成了包含(5-呋喃-2-基)苯甲酸或(5-噻吩-2-基)苯甲酸片段的一系列卤代2-芳基亚胺-3-芳基-噻唑烷-4-酮,并在体外评估了它们的抗菌活性、抗生物膜活性、红细胞溶血和细胞毒性。化合物(7c、7f、7i、7n和7p)表现出优异的抑制表皮葡萄球菌ATCC35984生长的功效(最小抑制浓度(MIC):0.8 μg/mL)。这五种化合物还显示出对表皮葡萄球菌ATCC35984有前景的抗生物膜活性,并且均未表现出明显的溶血活性和细胞毒性。进一步研究了选定的五种化合物(7c、7f、7i、7n和7p)对临床分离株(耐甲氧西林表皮葡萄球菌和耐甲氧西林金黄色葡萄球菌)的抗菌效果,并与甲氧西林和氨苄西林进行了比较。7p在合成的化合物中显示出最强的抗菌活性。
