In the present work 15 new 1,4-dihydropyridines (DHPs) bearing a coumarin ring were synthesized and assessed on 4 different human cancer cell lines (HeLa, K562, LS180, and MCF-7). Although, all the derivatives were inactive on LS180 cell line, the results on other cells showed that these compounds had weak to moderate antitumoral activities and their IC(50)(More)
4-Hydroxycoumarins constitute the structural nucleus of many natural products, drugs, and pesticides. Promising biological properties in new families of synthetic coumarins were recently reported. Therefore, 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,(More)
In the present work, novel 7-aryl-10, 11-dihydro-7H-chromeno [4, 3-b]quinoline-6, 8(9H, 12H)-dione derivatives were synthesized by oxidation of 7-aryl-8, 9, 10, 12-tetrahydro-7H-chromeno[4, 3-b]quinoline-6, 8-diones in the presence of silica sulfuric acid/NaNO2 with yields of 64-74%. Cytotoxic activity of synthesized compounds was assessed on three(More)
