Tridentate NNO donor Schiff base ligand and its mixed ligand zinc(II) complexwere synthesized stoichiometrically and characterized by electronic, infrared,mass spectral techniques and elemental analysis. To understand the DNA bindingability, the complex was investigated by various analytical and spectroscopictechniques in presence of calf thymus DNA (CT-DNA). The bindingstudies showed that the zinc complex interacts with DNA by groove bindingmode with intrinsic binding strength of 2.11 105 M1 and with bovine serumalbumin the complex showed dynamic quenching attributed for changes inthe secondary structure of BSA with efficient interaction. The MCF-7 cell linestudies of the zinc(II) complex with 90.8 μM IC50 value revealed that the complexis effective for the breast cancer cell line and has a potential as anticancerdrug. Furthermore, the tridentate ligand and its mixed ligand zinc complexwere screened for antibacterial and antifungal activities, which showed betterantimicrobial activity for complex.
