摘要
采用微波辅助法,以α-氨基膦酸酯和水杨酸为原料,以CDI/DMAP为催化剂,合成了10个结构新颖的水杨酸-α-氨基膦酸酯衍生物,所有目标化合物的结构均经IR,~1H-NMR,~(13)C-NMR和HRMS确认.优化反应条件:微波功率700 W、反应3 h.利用MTT法测定了目标化合物的抗肿瘤活性,结果显示,目标化合物对用于测试的三种肿瘤细胞:人急性髓系白血病细胞(KGla)、人肝癌细胞(HepG2)、宫颈癌细胞(Hela)均有一定的抑制作用,其中2E、2F对Hela抑制作用较好.
In this paper,ten novel salicylic acid-α-aminophosphonate derivatives were synthesized through the microwaved-assisted method,usingα-aminophosphate derivatives and o-hydroxybenzaldehydes in DCC/DMAP.All of the target compounds were characterized by IR,1H-NMR,~(13)C NMR and HRMS.The optimum conditions were as following:microwaved reaction at 700 W for 3 h.The antitumor activity of the target compounds was determined by MTT method.The results showed that the target compounds had inhibitory effects against three kinds of tumor cells:human acute myeloid leukemia cells(KGla),human hepatoma cells(HepG2),cervical cancer cells(Hela).Among the ten compounds,2E,2F showed a good inhibitory activity against cells Hela.
