Interaction study of some macrocyclic inorganic schiff base complexes with calf thymus DNA using spectroscopic and voltammetric methods
2018
Abstract The interaction of Cd(II), Zn(II) and Mn(II)-L (4,8-bis(2-pyridylmethyl)-4,8-diazaundecane-1,11-diamine) transition metal complexes with calf thymus DNA (CT-DNA) has been investigated using electronic, fluorescence and circular dichroism (CD) spectroscopy, thermal denaturation and cyclic voltammetry (CV). Based on the UV–Vis study, binding constants of the complexes with CT-DNA were calculated. Changes in the band of the CD spectrum, DNA melting temperature and in the ipa and ipc of the complexes in the presenceCT-DNA, overall, showed that the studied complex exhibited good DNA interaction ability with partial intercalation mode.
