-
摘要: 以梓醇、丙酸酐为原料,吡啶为溶剂和缚酸剂,利用微波辅助法合成梓醇全丙酰化衍生物(CP-6),通过正交试验对其合成条件进行优化,并采用四甲基偶氮唑盐微量酶反应比色法对其神经保护活性进行初步筛查.结果表明:当丙酸酐与梓醇物质的量比为18∶1,反应温度为80℃,反应时间为6 h,梓醇在吡啶中的质量浓度为25 g/L时,梓醇全丙酰化产物的相对含量可达98.51%;CP-6具有神经保护作用,是一种潜在的神经保护剂.Abstract: Using catalpol and propionyl anhydride as raw materials, pyridine as solvent and acid binding agent, catalpol perpropionyl product (CP-6) was synthesised by microwave-assisted method. The synthesis conditions were optimized by orthogonal test, and the neuroprotective activity was initially screened by the colorimetric method of the tetramethylazolyzol salt trace enzyme reaction. The test results showed that when the molar ratio of propionic anhydride to catalpol was 18:1, the reaction temperature in the microwave reactor was 80℃, the reaction time was 6 h, and the mass concentration of catalpol in pyridine was 25 g/L, the relative content of CP-6 in the reaction system could reach 98. 51%. MTT method was used to screen the neuroprotec tive activity of CP-6, and the results showed that CP-6 had neuroprotective effect and may be a potential neu roprotective agent.
