Synthesis of flavones, 4-thioflavones and 4-iminoflavones was carried out with the substitution of variable halogens, methyl, methoxy and nitro groups in the A, B and AB rings of the respective compounds and we also report here their antibacterial activity. Most of the synthesized compounds were found to be active against Escherichia coli, Bacillus subtilis, Shigella flexnari, Salmonella aureus, Salmonella
黄酮,4-硫代黄酮和4-亚氨基黄酮的合成是通过取代相应化合物的A,B和AB环中的可变卤素,甲基,甲氧基和硝基进行的,我们在此也报告了它们的抗菌活性。发现大多数合成的化合物对大肠杆菌,枯草芽孢杆菌,弗氏志贺氏菌,金黄色沙门氏菌,伤寒沙门氏菌和铜绿假单胞菌具有活性。发现4-硫代黄酮和4-亚氨基黄酮的活性高于其相应的黄酮类似物的活性。在环B的4'-位具有取代基(如F,OMe和NO2)的被研究化合物显示出增强的活性,所研究化合物中负电基团的存在与抗菌活性直接相关。
