A series of 2-imino-2H-chromen-3-yl-1,3,5-triazine compounds 5–12, which are namely hybrids of 2,4-diamino-1,3,5-triazines and 2-imino-coumarins, was synthesized by reacting 2-(4,6-diamine-1,3,5-triazin-2-yl)acetonitriles 1–4 with 2-hydroxybenzaldehydes. After this, upon heating in aqueous DMF, 2-imino-2H-chromen-3-yl-1,3,5-triazines 10 and 12 were converted into the corresponding 2H-chromen-3-yl-1,3,5-triazines 13 and 14, which are essentially hybrids of 2,4-diamino-1,3,5-triazines and coumarins. The in vitro anticancer activity of the newly prepared compounds was evaluated against five human cancer cell lines: DAN-G, A-427, LCLC-103H, SISO and RT-4. The greatest cytotoxic activity displayed 4-[7-(diethylamino)-2-imino-2H-chromen-3-yl]-6-(4-phenylpiperazin-1-yl)-1,3,5-triazin-2-amine (11, IC50 in the range of 1.51–2.60 μM).
一系列2-亚氨基-2H-香豆-3-基-1,3,5-三嗪化合物5–12被合成,这些化合物是2,4-二氨基-1,3,5-三嗪和2-亚氨基香豆素的杂合物。合成方法是将2-(4,6-二氨基-1,3,5-三嗪-2-基)乙腈1–4与2-羟基苯甲醛反应。随后,在水相DMF中加热,化合物2-亚氨基-2H-香豆-3-基-1,3,5-三嗪10和12转化为相应的2H-香豆-3-基-1,3,5-三嗪13和14,这基本上是2,4-二氨基-1,3,5-三嗪和香豆素的杂合物。新合成化合物的体外抗癌活性在五种人类癌细胞系(DAN-G,A-427,LCLC-103H,SISO和RT-4)中进行了评估。显示出最大细胞毒性活性的化合物为4-[7-(二乙氨基)-2-亚氨基-2H-香豆-3-基]-6-(4-苯基哌嗪-1-基)-1,3,5-三嗪-2-胺(11,IC50范围为1.51–2.60 μM)。
