2-(p-(Substituted)phenyl)-5-(3-(4-ethylpiperazine-1-yl) propionamido)benzoxazole derivatives (B7-B11) were designed, synthesized, and their antimicrobial activities were determined by the microdilution method. The novel benzoxazole compounds were characterized using FTIR, 1H NMR, and 13C NMR spectroscopy, mass spectroscopy, and elemental analysis. B7 and B11 showed promising activity against P. aeruginosa isolate at
本研究设计、合成了五种新的2-(对-(取代)苯基)-5-(3-(4-乙基哌嗪-1-基)丙酰胺基)苯并恶唑衍生物( B7 - B11 ),并对其抗菌活性进行了研究。微量稀释法测定。使用 FTIR、1 H NMR 和13 C NMR 光谱、质谱和元素分析对新型苯并恶唑化合物进行了表征。B7和B11对铜绿假单胞菌显示出有希望的活性与参考药物相比,分离浓度为 16 µg/mL。使用密度泛函理论 (DFT) 和 B3LYP/6–311G(d,p) 水平对五种基态化合物进行了量子力学计算。还对化合物的分子对接研究进行了 DNA 促旋酶与环丙沙星 (PDB: 2XCT) 的复杂结构,观察到结合姿势与环丙沙星相似。化合物的理论 ADME 曲线符合 Lipinski 和其他限制规则。
