Binding of Natural Antioxidant, Curcumin with Metal-Salen Complexes

Six transition metal-salen complexes (metal = Fe, Mn and Cr) 1-6 have been synthesized and characterized using different spectroscopic and electrochemical techniques. The binding studies of natural antioxidant, curcumin with the complexes (1-6) have been carried out by electronic absorption spectroscopic technique. The substantial shift in the absorption maximum of complexes (1-6) when they bin...

A Straightforward Electrochemical Approach to Imine‐ and Amine‐bisphenolate Metal Complexes with Facile Control Over Metal Oxidation State

Synthetic methods to prepare organometallic and coordination compounds such as Schiff-base complexes are diverse, with the route chosen being dependent upon many factors such as metal-ligand combination and metal oxidation state. In this work we have shown that electrochemical methodology can be employed to synthesize a variety of metal-salen/salan complexes which comprise diverse metal-ligand ...

Bioactive Salen-type Schiff Base Transition Metal Complexes as Possible Anticancer Agents

Although metal-based anticancer drugs have been recognized as the most effective agents over the organic compounds, non-selectivity and high toxic effects have limited their applications in a way that only three Pt-analogues have progressed into clinical use. These problems have spurred chemists to develop different strategies based on alternative targets. This work focuses on predicting potenc...
