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。

A type of novel alpha,beta-unsaturated cyclohexanone analogous, which designed based on the curcumin core structure, have been discovered as potential EGFR inhibitors. These compounds exhibit potent antiproliferative activity in two human tumor cell lines (Hep G2 and B16-F10). Among them, compounds I-3 and I-12 displayed the most potent EGFR inhibitory activity (IC50 = 0.43 mu M and 1.54 mu M, respectively). Molecular docking of I-12 into EGFR TK active site was also performed. This inhibitor nicely fitting the active site might well explain its excellent inhibitory activity. (C) 2012 Elsevier Ltd.

series of curcumin derivatives as potent dualinhibitors of xanthine oxidase (XOD) and urate transporter 1 (URAT1) was discovered as anti-hyperuricemic agents. These compounds proved efficient effects on anti-hyperuricemic activity and uricosuric activity in vivo. More importantly, some of them exhibited proved efficient effects on inhibiting XOD activity and suppressing uptake of uric acid via URAT1 in
