Three 2-amino-4-(trifluoromethylphenyl)-3-cyano-7-(dimethylamino) -4H-chromene derivatives were synthesized and their cytotoxic activities were determined against six human tumor cell lines using MTT assay. Condensation of 3-(dimethylamino)phenol, trifluoromethybenzaldehydes and malonitrile in ethanol containing piperidine afforded corresponding chromenes(4a-c). The structure of the synthesized compound was confirmed by1H NMR, IR and Mass spectral data. Among compounds tested, 3-trifluoromethyl analogue(3b)was the most active against all human tumor cell lines (IC50=12-45 nM).
三种2-氨基-4-(三氟甲基苯基)-3-氰基-7-(二甲基氨基)-4H-香豆素衍生物被合成,并通过MTT测定对六种人类肿瘤细胞系的细胞毒活性进行了测定。在含有哌啶的乙醇中,将3-(二甲基氨基)苯酚、三氟甲基苯甲醛和马来酰亚胺缩合得到相应的香豆素(4a-c)。合成化合物的结构经由1H NMR、IR和质谱数据得到确认。在测试的化合物中,3-三氟甲基类似物(3b)对所有人类肿瘤细胞系表现出最高的活性(IC50=12-45 nM)。
