Pyridoxal Hydrochloride

New series of copper (II), cobalt (II), zinc (II), nickel (II), manganese (II), iron (II) complexes of a novel Schiff base were prepared by the condensation of sulphadizine and pyridoxal hydrochloride. The ligand and metal complexes were characterized by utilizing different instrumental procedures like microanalysis, thermogravimetric examination and spectroscopy. The integrated ligand and transition metal complexes were screened against various bacteria and fungus. The studies demonstrated the enhanced activity of metal complexes against reported microbes when compared with free ligand.

Scorpionate Ligands

: The development of safe and effective chemotherapeutic agents is one of the uppermost priorities and challenges of medicinal chemistry and new transition metal complexes are being continuously designed and tested as anticancer agents. Scorpionate ligands have played a great role in coordination chemistry, since their discovery by Trofimenko in the late 1960s, with significant contributions in the fields of catalysis and bioinorganic chemistry. Scorpionate metal complexes have also shown interesting anticancer properties, and herein, the most recent (last decade) and relevant scorpionate complexes reported for application in medicinal chemistry as chemotherapeutic agents are reviewed. The current progress on the anticancer properties of transition metal complexes bearing homo- or hetero- scorpionate ligands, derived from bis- or tris-(pyrazol-1-yl)-borate or -methane moieties is highlighted.
