黄皮酰胺的抑制脂质过氧化和脑保护作用

黄皮酰胺是类似脑复康结构的一种化合物。实验表明po能明显延长小鼠断头后的张口呼吸时间和sc亚硝酸钠225 mg/kg后的动物存活时间。po黄皮酰胺100 mg/kg·bid×3能抑制由p0 50%乙醇(15 ml/kg)诱发小鼠肝脂质过氧化反应,使TBA反应值下降,明显激活肝和脑组织胞浆液中谷胱甘肽过氧化酶的活力。大鼠脑基底动脉条收缩实验结果表明,黄皮酰胺10^-5mol/L可明显抑制由5-HT,PGF_2x和花生四烯酸引起的血管收缩,提示黄皮酰胺有缓解血管痉挛,增加脑血流量的作用。

ANTI-LIPIDPEROXIDATION AND CEREBRAL PROTECTIVE EFFECTS OF CLAUSENAMIDE

Clausenamide is a compound isolated from Clausena lansium (lour) with the structure similar to piracetam. Pharmacological experiments showed that clausenamide po 100-200 mg/kg prolonged both the duration of gasping after decapitation and the survival time after sc NaNO2 225 mg/kg, clausenamide at the concentration of 10(-5) mol/L inhibited the contraction of basilar artery caused by 5-HT, PGF2 alpha and arachidonic acid, indicating that clausenamide is a cerebral protective agent. In addition, multiple doses clausenamide were shown to inhibit the liver lipid peroxidation caused by 50% alcohol and increase the GSH-peroxidase activity significantly in rat liver and brain cytosol.
