Abstract

Introduction:

A new series of mononuclear Fe(II), Co(II), Ni(II), Cu(II) and Pd(II) complexes correspond to tetradentate macrocyclic nitrogen ligand i.e. naphthyl-3,4:10,11-dibenzo,7-methylene,8-methyl,6-phenyl-1,5,9,13-tetraazacyclohexadecane-5,8-diene-2,12-dione metal(II) complexes, have been synthesized by the template condensation reaction.

Methods:

The complexes have been characterized by elemental analysis, spectral (IR, UV–Vis, and ESR, molar conductivity, and magnetic as well as thermal analysis measurements.

Results:

On the basis of above studies, an octahedral geometry has been proposed for all complexes except Cu(II) nitrate complex that adopt square pyramidal geometry, and square planar geometry for Pd(II) chloride complex, respectively.

Conclusion:

The thermal behavior and the kinetic parameters of degradation were determined using Coats-Redfern and Horowitz-Metzger methods. Moreover, the in vitro antitumor activity of the some synthesized complexes against human breast and human hepatocarcinoma cell lines (MCF-7) and (HePG2), respectively has been studied.

Keywords: Tetra-azamacrocyclic, Macrocyclic metal complexes, Monobenzoylacetone, Spectral studies, Antitumor activity, IC50.

I am completely satisfied with the service I received from Bentham Science Publishers, right from the submission of our research paper in ‘Open Chemistry’ to its publication in the journal. The reviewers' and editor's comments were very helpful in improving the paper.

I take this opportunity to express my appreciation to the whole team of BSP!
