Hydrazylpyridine salicylaldehyde-copper(II)-1,10-phenanthroline complexes as potential anticancer agents: synthesis, characterization and anticancer evaluation.

We synthesized and analyzed nine unique copper(II) hydrazylpyridine salicylaldehyde and 1,10-phenanthroline complexes, [Cu(L)(phen)] (Cugdupt1), [Cu(L)(phen)]·(CHCN) (Cugdupt2), [Cu(L)(phen)] (Cugdupt3), [Cu(L)(phen)]·(CHCN) (Cugdupt4), [Cu(L)(phen)] (Cugdupt5), [Cu(L)(phen)] (Cugdupt6), [Cu(L)(phen)] (Cugdupt7) [Cu(L)(phen)] (Cugdupt8) and [Cu(L)(phen)]·0.5(HO) (Cugdupt9). We were motivated by the intriguing properties of the coupled ligands of hydrazylpyridine, salicylaldehyde, and 1,10-phenanthroline.
