Abstract

To evaluate the biotransformation and the mechanism of binding as well as the biological impact of metal-based- drugs involving Pd(II), known to have high potency and low toxicity for use as anticancer therapeutics, in the present study, a newly synthesized palladium (II) complex, [Pd(CPF)(OH2)2]2+ (where CPF is ciprofloxacin), has been synthesized and characterized and thoroughly evaluated for its antimicrobial properties. The interaction of the diaqua complex with CT-DNA and BSA was studied through various techniques, including UV-vis spectroscopy, thermal denaturation, viscometry, gel electrophoresis, ethanol precipitation, and molecular docking studies. The results indicate that the complex exhibits a robust binding interaction with CT-DNA, possibly via minor groove binding and (or) electrostatic interactions. Furthermore, the complex displays good binding affinity towards BSA, indicating its potential as a target for DNA and BSA in biological media. The invitro cytotoxicity assay reveals that this complex can be classified as a promising cell growth inhibitor against MCF-7, HT-29, and A549. Thus, this newly synthesized palladium (II) complex is a promising candidate for further exploration as a potential anticancer therapeutic.

Keywords: Anti-microbial; Ciprofloxacin; Cytotoxicity; Molecular docking; Palladium(II).
