摘要 运用分子力学和量子化学计算的方法,研究益智酮A与其类似物姜黄色素抗氧化性的构效关系。从电荷、键长和生成热之差分析益智酮A与姜黄色素的抗氧化性,结果表明益智酮A的姜黄色素因具有相同的结构而具有类似的抗氧化性,但因所带的电荷和生成热之差不同而存在抗氧化性强弱的差异。 Molecular mechanics and quantumchemistry methods was used to study the effect quarititative structure-activity relationship (QSAR) on the antioxidative activities of yakuchinone A and curcumin. The energy and electronic structures of the cureumin compounds including yakuchinone A and curctunin were calculated. The change of enery and electronic stnlcture from free radicals were acounted and like curcumin compounds there the active process of the curcumin compounds dehydrogenation oxidation was take place. Results showed that the structure stabilities of curcumin and yakuchinone A are reactive to their molecular structure.
