bond between aromatic acid and 4-phenylthiazol-2-amine or 4-(4-bromophenyl)thiazol-2-amine. These thiazole derivatives have evaluated as potent FabH inhibitors. Nineteen compounds (4b–4h, 4k, 4l, 5a–5h, 5k, 5l) are reported for the first time. Most of the synthesized compounds exhibited antibacterial activity in the MTT assay. The MIC value of these compounds ranged from 1.56 μg/mL to 100 μg/mL. Moreover
脂肪酸生物合成途径的组成已被确定为开发新型抗菌剂的有吸引力的目标。A系列(4a - 4g)和B系列(5a - 5g)的化合物是通过在芳族酸和4-苯基噻唑-2-胺或4-(4-溴苯基)噻唑-2-胺之间形成胺键合成的。这些噻唑衍生物已被评估为有效的FabH抑制剂。19种化合物(4b – 4h,4k,4l,5a – 5h,5k,5l)是首次报告。大多数合成的化合物在MTT分析中显示出抗菌活性。这些化合物的MIC值在1.56μg/ mL至100μg/ mL的范围内。此外,测试化合物还显示出FabH抑制能力,IC 50值在5.8μM至48.1μM的范围内。IC 50值接近MIC值。化合物5f具有最佳的抗菌和大肠杆菌FabH抑制活性。进行了对接模拟和QSAR研究,以了解结合模式以及结构与活性之间的关系。
