We report here on the synthesis and in vitro anti-tumor effects of a series of novel 1,2,4-triazole (compounds 3–6), 4,5-dicyanoimidazole (compound 7), and purine (compounds 8–13) coumarin derivatives and their acyclic nucleoside analogues 14–18. Structures of novel compounds 3–18 were deduced from their 1H- and 13C-NMR and corresponding mass spectra. Results of anti-proliferative assays performed on a panel of selected human tumor cell lines revealed that compound 6 had moderate cytostatic activity against the HeLa cell line (IC50 = 35 µM), whereas compound 10 showed moderate activity against the HeLa (IC50 = 33 µM), HepG2 (IC50 = 25 µM) and SW620 (IC50 = 35 µM) cell lines. These compounds showed no cytotoxic effects on normal (diploid) human fibroblasts.
