characteristic of flavonoid. 3-OH and 3-O-substituted groups on the C-ring exhibited the deactivated aminomethylation at C-6 position, whereas substitution at this position was independent on bond feature at C-2 and C-3 on the C-ring. Screening anti-proliferative activity showed six flavonoids possessed activity against breast cancer cell, MDA-MB-231. Among them, the flavonoids, luteolin (2) and 3′,4′,5,7-tetrahydroxy-6
我们在此报道了各种结构类黄酮的曼尼希氨基甲基化及其对人乳腺癌细胞的生物学评价。曼尼希反应表明,C-6位的取代取决于胺的碱性和类黄酮的C环特征。所有五种类黄酮底物均与强胺碱反应生成双(6,8-氨基甲基)衍生物,而与弱胺类反应,则取决于类黄酮的结构特征而获得了不同的产物。3-OH和3- OC环上的取代基在C-6位上表现出失活的氨基甲基化,而在该位置上的取代独立于C环上C-2和C-3上的键特征。筛选抗增殖活性表明六种类黄酮具有抗乳腺癌细胞MDA-MB-231的活性。其中,类黄酮,木犀草素(2)和3',4',5,7-四羟基-6,8-双(吡咯烷-1-基甲基)-3-芸香糖基黄酮(3a)表现出最高的抗增殖活性具有最低的IC 50值。
