New 2,3-substituted-1,3-thiazolidin-4-one (6a-f) were prepared by cyclocondensation of 2-[6-(4-chlorobenzyloxy)-2-naphthyliden]-4-(4-substituted phenyl)-5-methyl-1,3-thiazole (5a-f) and mercaptoacetic acid in benzene. The synthesized compounds were characterized on the basis of elemental analysis, 1H NMR, 13C NMR and FT-IR. The prepared compounds have been screened in vitro against two Gram-positive Staphylococcus aureus, Staphylococcus epidermidis, and two Gram-negative Escherichia coli, Pseudomonas aernuginosa for antibacterial activity and two fungal strains Candida albicans, Candida krusei for antifungal activity using ciprofloxacin, ampicillin and ketoconazole with minimal inhibitory concentration (MIC) value of 10 mcg/L in DMSO. Compounds 6a and 6d showed good antibacterial and antifungal activities compared to reference medications utilized within this study.
新型2,3取代的1,3-噻唑烷-4-酮(6a-f)是通过将2-[6-(4-氯苄氧)-2-萘烯]-4-(4-取代苯基)-5-甲基-1,3-噻唑(5a-f)与巯基乙酸在苯中缩合制备的。合成的化合物通过元素分析、1H NMR、13C NMR和FT-IR进行表征。所制备的化合物在体外针对两种革兰阳性菌金黄色葡萄球菌、表皮葡萄球菌和两种革兰阴性菌大肠杆菌、铜绿假单胞菌进行抗菌活性筛选,以及针对两种真菌菌株白色念珠菌、克鲁斯氏念珠菌进行抗真菌活性评估,使用环丙沙星、氨苄青霉素和酮康唑,最低抑菌浓度(MIC)值为10 mcg/L在DMSO中。化合物6a和6d相较于本研究中使用的参考药物显示出良好的抗菌和抗真菌活性。
