An array of previously synthesized 4-methyl-7-amino and amido coumarins 4a–u has been screened for their antimicrobial and antioxidant properties. Some of the compounds exhibited promising antibacterial and antifungal activities (MIC ranging from 4–64 μg/mL) when compared to the respective standards. Compound 4u showed comparable antibacterial activity with the standard, ciprofloxacin, whereas compounds 4u and 4t displayed promising antifungal activity when compared to the standard, fluconazole. The in silico docking studies against gyrase enzyme revealed the fact that 4u possessed hydrogen bonding and significant hydrophobic interactions, which may be the reason for its superior antibacterial activity as compared to the other compounds. Compounds 4c and 4m showed comparable antioxidant activity with the standard, BHT, which can be attributed to the presence of electron-donating substituents.
一批先前合成的4-甲基-7-氨基和酰胺香豆素4a–u已被筛选其抗菌和抗氧化性能。与各自的标准相比,一些化合物表现出有前景的抗菌和抗真菌活性(MIC范围为4-64 μg/mL)。化合物4u显示出与标准环丙沙星相当的抗菌活性,而化合物4u和4t在与标准氟康唑相比时显示出有前景的抗真菌活性。针对拓扑异构酶的计算对接研究揭示了4u具有氢键和显著的疏水相互作用,这可能是其相对于其他化合物具有更优越抗菌活性的原因。化合物4c和4m显示出与标准BHT相当的抗氧化活性,这可以归因于存在供电子取代基。
