Selective Complexation of Hydrazone Based Ketimine with 3d, 4d, and 5d Metals: Synthesis, Characterization, and Biological Activity

Аннотация

The hydrazone derived ketimine of dehydroacetic acid and its metal {Cu(II), Ni(II), Zn(II), Fe(III), Cd(II), Pd(II), La(III), Nd(III), Ce(III)} complexes are synthesized and characterized by IR, ¹H and ¹³C NMR, and UV-Vis spectroscopy. DNA studies have been carried out for metal complexes by electronic absorption spectroscopy. It is determined that metal complexes bind to DNA through intercalation. The complexes of Cu(II), Zn(II) and Pd(II) demonstrate significant activity against HeLa cells (cervical cancer).
