摘要:

7-羟基黄酮与过量1,2-二溴乙烷反应得到7-溴乙氧基黄酮, 将其分别与3-取代-4-氨基-1,2,4-三唑-5-硫酮肉桂醛席夫碱、 3-取代-4-苯基-5-巯基-1,2,4-三唑、 3-(α-萘亚甲基)-5-巯基-1,2,4-三唑及3-巯基-5-氨基-1,2,4-三唑肉桂醛席夫碱反应, 得到4类共16个7-三唑硫乙氧基黄酮类衍生物. 采用红外光谱(IR)、 核磁共振氢谱(1H NMR)、 质谱(MS)及元素分析(EA)等方法对化合物的结构进行了确证. 测定了目标化合物清除超氧自由基()、 羟自由基(·OH)和2,2-二苯基-1-苦味酰基自由基(DPPH·)的活性及总还原能力, 并测定了其抗菌活性. 结果表明, 多数化合物在0.5 mg/mL浓度时具有抗DPPH·活性, 其中7-(5-苯亚甲基-4-苯基烯丙亚胺基-1,2,4-三唑-3-硫乙氧基)黄酮(1i)活性较强; 多数化合物表现了较好的抑菌活性, 其中7-(5-苯亚甲基-4-苯基-1,2,4-三唑-3-硫乙氧基)黄酮(2c)对大肠杆菌、 金黄色葡萄球菌和黑曲霉均具有较强的抑制作用.

Abstract:

Flavone and 1,2,4-triazole derivatives have many different biological activities. According to the active groups combination principle, sixteen 7-(substituted triazolo thioethoxy)flavone derivatives were synthesized by means of the condensation reaction of 7-bromoethoxy flavone, which was synthesized from 7-hydroxy flavone and 1,2-dibromoethane, with four types of 1,2,4-triazole compounds, such as 3-substituted-4-phenylallylideneamino-1,2,4-triazol-5-thiones, 3-substituted-4-phenyl-5-mercapto-1,2,4-triazoles, 3-(α-naphthylmethene)-5-mercapto-1,2,4-triazole and 3-mercapto-5-phenylallylideneamino-1,2,4-triazole. These new compounds were characterized via IR, 1H NMR, MS and elementary analysis. Their scavenging effects on the superoxide radical(), hydroxyl radical(·OH) and DPPH· radical and their total reduction activities were compared, and the in vitro antimicrobial activities were also tested. The results showed that at the concentration of 0.5 mg/mL, some of the title compounds had scavenging effects on DPPH·, among which 7-(5-phenylmethylene-4-phenylallylideneamino-1,2,4-triazol-3-thioethoxy)flavone(1i) had stronger effect than the others, and the title compound had relatively antibacterial activity, among which 7-(5-phenylmethylene-4-phenyl-1,2,4-triazol-3-thioethoxy)flavone(2c) had stronger effect on E. coli, S. aureus and A. niger than the others.
