The present invention discloses a α-(3,5-dimethoxybenzylidene)-α′-hydrocarbyl methylene cyclic ketone with the following formula:
wherein R is aryl or alkyl, its preparation method is: the cyclic ketone blended with morpholine are subjected to azeotropic dehydration to give enamine, the enamine is condensed with 3,5-dimethoxybenzaldehyde and then condensed with alkyl or aryl formaldehyde under acidic or basic conditions to give the product, the present invention further discloses an antitumor agent comprising α-(3,5-dimethoxybenzylidene)-α′-hydrocarbyl methylene cyclic ketone or medically acceptable salts and pharmaceutically acceptable carriers thereof. Through the above, the present invention provides α-(3,5-dimethoxybenzylidene)-α′-hydrocarbyl methylene cyclic ketone and preparation method thereof, the said compound is a high activity antitumor agent obtained by piecing and modifying the formulas of natural anti-tumor active ingredient resveratrol and curcumin, which has a good inhibitory effect on epidermal growth factor receptor.
本发明揭示了一种具有以下结构式的 α-(3,5-二甲氧基苄亚基)-α′-烃基亚甲基环酮:其中 R 为芳基或烷基,其制备方法为:将环酮与吗啉混合物经过共沸脱水得到烯胺,将烯胺与3,5-二甲氧基苄醛缩合,然后在酸性或碱性条件下与烷基或芳基甲醛缩合得到产物,本发明还揭示了包含 α-(3,5-二甲氧基苄亚基)-α′-烃基亚甲基环酮或其医学上可接受的盐和药学上可接受的载体的抗肿瘤剂。通过上述方法,本发明提供了α-(3,5-二甲氧基苄亚基)-α′-烃基亚甲基环酮及其制备方法,该化合物是通过拼接和修改天然抗肿瘤活性成分白藜芦醇和姜黄素的结构式而获得的高活性抗肿瘤剂,对表皮生长因子受体具有良好的抑制作用。
