Abstract |
Two water soluble heterometallic potassium-dioxidovanadium polymers, [KVO2(L-1)](n) (1) and [KVO2(L-2)(H2O)](n) (2) [H2L1 = (2,3-dihydroxybenzylidene)-2-hydroxybenzohydrazide and H2L2 = (2,3-dihydroxybenzylidene)benzohydrazide], have been synthesized and characterized by IR, NMR, elemental analysis and single crystal X-ray diffraction. The antiproliferative potentials of 1 and 2 were examined towards human colorectal carcinoma (HCT116), and lung (A549) and breast (MCF7) adenocarcinoma cell lines. 1 exhibits a high cytotoxic activity against colorectal carcinoma cells (HCT116), with IC50 lower than those for cisplatin.
