for in vitro antioxidant and antibacterial activity. Among all tested compounds 2a, 2c, 2e, and 2h showed good chelating ability with Fe+2 ions, whereas compounds 2g and 2j exhibited good scavenging activity with DPPH free radicals. Concerning antibacterial activities compounds 2a, 2b, 2c, and 2h were found to be equipotent to ampicillin against Enterococcus sp and Staphylococcus aureus, while compound
通过2-(1-苯并呋喃)的反应合成了一系列新的2-(1-苯并呋喃-2-基)喹啉-4-羧酸酚酯2(a – j)和酰胺3(a – c)。使用乙基-(N ',N'-二甲基氨基)丙基碳二亚胺盐酸盐(EDC.HCl)作为偶联剂的具有各种取代酚和仲胺的-2-基)-喹啉-4-羧酸(1)。评价了新合成的化合物的体外抗氧化和抗菌活性。在所有测试的化合物2a,2c,2e和2h中与Fe +2离子具有良好的螯合能力,而化合物2g和2j对DPPH自由基具有良好的清除活性。关于抗菌活性,发现化合物2a,2b,2c和2h与氨苄青霉素对肠球菌sp和金黄色葡萄球菌等价,而化合物2e对氨苄西林对Pantoea Dispersa和Ochrobactrum sp的效力一样。酰胺衍生物3(a – c与标准产品相比,)被发现效力较低。
