worldwide and endangering the efficacy of antibiotics. Hence, the development of novel and potent antibacterial is a need of the day. Objective: In this study, we designed and synthesized compounds C1-C11. These compounds are characterized by their FT-IR, NMR and MS spectral data and examined in vitro for their antibacterial activity. Methods: Compounds C1-C11 were synthesized by reacting 2-mercaptobenzothiazole
背景:全球范围内细菌耐药性的惊人上升正在危及抗生素的功效。因此,开发新型有效的抗菌剂是当今的需要。目的:本研究设计并合成了化合物C1-C11。这些化合物通过 FT-IR、NMR 和 MS 光谱数据进行表征,并在体外检查其抗菌活性。方法:在无水碳酸钾和干燥丙酮存在下,2-巯基苯并噻唑与适量的氯乙酰胺在室温下反应合成化合物C1-C11。为了评估抗菌活性,通过肉汤微量稀释法对选定的革兰氏阳性菌和革兰氏阴性菌菌株进行了最低抑制浓度和最低杀菌浓度的检测。还根据 CLSI 指南进行了时间杀死动力学研究。结果:化合物 C6 和 C7 对金黄色葡萄球菌 ATCC 43300 表现出良好的活性,MIC 分别为 9.43 和 7.73 μM。这两种化合物还对金黄色葡萄球菌 5021 表现出良好的抗菌活性,MIC 值分别为 7.53 和 9.68 μM。在 MBC 测定中,这两种化合物(测试浓度范围为 7.53
