咖啡酸苯乙酯衍生物对实验性肝损伤小鼠的保护作用

目的:研究咖啡酸苯乙酯衍生物对CCl4诱导的小鼠实验性肝损伤的保护作用.方法:选取50只雄性昆明小鼠,随机分为5组:空白对照组,模型对照组,咖啡酸苯乙酯衍生物高、中、低剂量实验组.饲养15d后,正常组腹腔注射橄榄油溶液,其余各组腹腔注射0.15%CCl4橄榄油溶液(0.01mL/g).24h后采血,检测血清AST,ALT水平.处死小鼠,制备肝组织匀浆测定SOD、MDA的质量分数.结果:咖啡酸苯乙酯衍生物组均可显著降低CCl4所致急性肝损伤小鼠血清AST和ALT活性及肝组织MDA质量分数(p<0.05),提高肝组织SOD质量分数(p<0.05).结论:咖啡酸苯乙酯衍生物-咖啡酸对硝基苯乙酯对CCl4所致急性肝损伤有一定的保护作用.

Caffeic acid phenethyl ester and its benzoyl derivatives:synthesis and X-ray structural analysis

Caffeic acid phenethyl ester （CAPE）, the main biologically active component of propolis, has been successfully synthesized from caffeic acid and β-bromoethylbenzene catalyzed by Na2CO3 in a mixed solvent of HMPA-CH3CN. To better understand the struc^re-activity relationship of CAPE, phenylethyl-monobenzoylcinnamate and phenylethyl-dibenzoylcinnamate were prepared. Meanwhile, the structure of phenylethyl-monobenzoylcinnamate was confirmed by single-crystal X-ray diffiaction.
