evaluated for their antimicrobial and total antioxidant activity using in vitro well diffusion method and phosphomolybdenum method, respectively. Amongst all the compounds, 4c has shown potential antimicrobial and antioxidant activity against the standard. All compounds have exhibited good binding energies from −4.46 to −5.70 kcal/mol against 24-kDa DNA gyrase B fragment from E. coli (PDB ID-1KZN) in molecular
通过用各种胺处理2-(2-oxo-2H-chromen-4-yloxy)乙酸3合成了一系列新颖的4-羟基香豆素衍生物4a-n。由相应的酯2的水解得到酸3,该酯由4-羟基香豆素1和溴乙酸乙酯制备。所有合成的化合物4a–n使用光谱技术进行表征。分别使用体外孔扩散法和磷钼法评估了合成的化合物4a–n的抗菌和总抗氧化活性。在所有化合物中,4c对标准显示出潜在的抗微生物和抗氧化活性。在分子对接研究中,所有化合物对大肠杆菌的24 kDa DNA促旋酶B片段(PDB ID-1KZN)均表现出从-4.46至-5.70 kcal / mol的良好结合能,其中4c显示出最大结合能。
