A bis-terpyridine monomer includes a first terpyridyl substituent (A), a second terpyridyl substituent (B), and a spacer that contains at least one benzene ring and links the first terpyridyl substituent (A) and the second terpyridyl substituent (B). The bis-terpyridine monomer is represented by the following formula (10):

of newly fusedpyrimidinederivatives against breast MCF-7 cancer was performed. It was apparent that the 2-phenylpyrazolo[1,5-a]pyrimidinederivatives 9a (IC50 = 9.12±1.16 µg/ml), 9c (IC50 = 9.10±1.07 µg/ml) and 9d (IC50 = 9.60±1.22 µg/ml) exhibited equipotent antitumor activity as Tamoxifen (IC50 = 9.11±0.90 µg/ml). Also, the inhibitory activity of the novel fusedpyrimidinederivatives on VEGFR-2

le), 13 (pyridinyl-isoxazole) and 16 (pyridinyl-benzo[b][1,4]thiazepine) had the maximum anticancer activity against all examined cell lines. Based on these resultss, we are able to conclude that analoges 6-Ethoxy-pyridine 3, Pyridinyl-pyrazol 8, Pyridinyl-N-(2,4-dinitrophenyl)pyrazole 11 and Pyridinyl-benzo[b][1,4]thiazepine 16 are found to be secure and specific because their IC50 values on normal
