Four (6,7-dimethoxy-2-oxo-2H-chromen-4-yl)methyl 3-arylacrylate (5a-d) analogues of the antitumor agent (6,7-dimethoxy-2-oxo-2H-chromen-4-yl)methyl 3-(4-methoxyphenyl)acrylate (2) were synthesized. The compounds 5a-d have one or two nitrogen atoms incorporated on the aryl moiety, and therefore could be converted into hydrochloride salts (6a-d) and these salts possess greater water solubility compared to 2. Antitumor activity evaluation of using BDF1 mice bearing 3LL tumor cells model demonstrated significant inhibitory effects of compounds 6a-d against tumor growth with inhibition rates from 37.2 to 48.2%.
抗肿瘤剂的四种(6,7-二甲氧基-2-氧代-2H-苯并-4-基)甲基3-芳基
丙烯酸酯(5a-d)类似物(6,7-二甲氧基-2-氧代-2H-苯并-4合成了3-(4-
甲氧基苯基)
丙烯酸(2)甲酯(2)。化合物5a-d在芳基部分上掺入了1个或2个氮原子,因此可以转化为盐酸盐(6a-d),并且这些盐与2相比具有更大的
水溶性。使用携带3LL的BDF1小鼠的抗肿瘤活性评价肿瘤细胞模型显示化合物6a-d对肿瘤生长具有显着的抑制作用,抑制率为37.2%至48.2%。
