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.

Therapeutic Compounds

Metal complexes are currently potential therapeutic compounds. The acquisition of resistance by cancer cells or the effective elimination of cancer-affected cells necessitates a constant search for chemical compounds with specific biological activities. One alternative option is the transition metal complexes having potential as antitumor agents. Here, we present the current knowledge about the application of transition metal complexes bearing nickel(II), cobalt(II), copper(II), ruthenium(III), and ruthenium(IV). The cytotoxic properties of the above complexes causing apoptosis, autophagy, DNA damage, and cell cycle inhibition are described in this review.

Spectral Studies

The study describes the synthesis, characterization and biological activity of a novel Schiff base ligand and its transition metal complexes. The Schiff base ligand was obtained by a condensation reaction between 4-hydroxy-3-methoxybenzaldehyde (p-vanillin) and hydrazine hydrate using ethanol as solvent. A new series of Ni(II) and Fe(III) complexes were also derived by reaction of prepared Schiff base ligand with NiCl2 and FeCl3. Both the ligand and its metal complexes were characterized by solubility, melting point and elemental analysis. These compounds were further identified by analytical techniques, FTIR, NMR and mass spectrometry. The ligand and its transition metal complexes were also subjected to in vitro biological activities i.e. antimicrobial, antiangiogenic and DNA photo cleavage. For antimicrobial activity compounds were tested against two strains of bacteria and two strains of fungi. Different concentrations of prepared compounds were treated with fertilized chicken eggs and plasmid DNA to find out antiangiogenic and DNA photocleavage activity, respectively.
