4-triazole-norfloxacin hybrids was designed, synthesized, and evaluated for in vitro antibacterial activity against common pathogens. All the newly synthesized compounds were characterized by Fourier-transform infrared spectrophotometry, proton and carbon nuclear magnetic resonance, and electrospray ionization-mass spectrometry. Representative compounds from each step of the synthesis were further characterized
一系列 1,2,4-三唑-诺氟沙星杂化物的设计、合成和体外评价对常见病原体的抗菌活性。所有新合成的化合物均通过傅里叶变换红外分光光度法、质子和碳核磁共振以及电喷雾电离质谱法进行表征。来自每个合成步骤的代表性化合物通过 X 射线晶体学进一步表征。许多合成的化合物对革兰氏阳性菌和革兰氏阴性菌均表现出优于诺氟沙星的抗菌活性。1,2,4-三唑-诺氟沙星杂交体对细菌细胞的毒性比对小鼠成纤维细胞的毒性高 32-512 倍。此外,在 64 μg/mL 的浓度下未观察到溶血,表明具有良好的生物相容性。分子对接显示最小结合能为 -9.4 至 -9.7 kcal/mol,
