Abstract
Zn(II) complex of 2-hydroxy-5-methoxyacetophenone thiosemicarbazone { Zn(HMAT)2} was synthesized and characterized by 1H NMR, UV–Vis and FT-IR spectroscopies. Further, X-ray powder diffraction (XRD) analysis of Zn(HMAT)2 was carried out to point out the complexation. The binding affinities of Zn(HMAT)2 with calf thymus DNA (CT-DNA) have been studied by using fluorescence and absorption titration technics. In addition, bovine serum albumin (BSA) binding studies were recorded by fluorescence and UV–Vis spectroscopy. Zn(HMAT)2 is a strong binders of CT-DNA with binding constant (Kb) 3.65×107 M−1. The binding parameters KSV (for EB), Kq (for BSA) and Kb (for BSA) were determined as 8.2×107 M−1, 1.8×1014 M−1 s−1 and 2×107 M−1 respectively.
