efficient synthesis of new benzopyrano[3,2-c]chromene-6,8-dione was undertaken and the structures of 15 compounds were confirmed by their IR, Mass, 1H-NMR, and C, H, N analysis. Then, the cytotoxic activities of these compounds were assessed on four different human cancer cell lines (Raji, HeLa, LS180, and MCF-7). The results showed that these compounds had weak-to-moderate antitumoral activities and their
4-羟基香豆素构成许多天然产物,药物和农药的结构核。最近报道了新的合成香豆素家族的有前途的生物学特性。因此,进行了新的苯并吡喃并[3,2-c]亚甲基-6,8-二酮的有效合成,并通过红外,质谱,1 H-NMR和C,H,N分析确认了15种化合物的结构。然后,在四种不同的人类癌细胞系(Raji,HeLa,LS180和MCF-7)上评估了这些化合物的细胞毒活性。结果表明,这些化合物具有弱至中度的抗肿瘤活性,其IC 50为49至100μM以上。在化合物9,10-二氢-7-(3-甲氧基苯基)-7 H,11 H-苯并吡喃并[3,2-c]色烯-6,8-二酮[ 4k ]表现出最高的活性。此外,构象分析表明邻位取代基明显不同于间位和对位取代基。
