Metal Complexes of Phenyl Glycine-O-Carboxylic Acid: Preparation, Characterization, Electrochemical and Biological Properties

Abstract

Metal complexes are the effective therapeutic compound and it became more emerging field in the drug discovery and delivery. A novel ligand phenyl-glycine -o- carboxylic acid was synthesized and further complexed with the metal (II) chlorides. The synthesized metal complexes was interpreted by FT-IR spectroscopy, Ultra Violet- visible, 1H-NMR, molar conductance, magnetic susceptibility and thermogravimetric study. The electrochemical properties of the ligand and its complexes were inquired in DMF. Antibacterial and fungal activities of the phenyl-glycine -o- carboxylic acid (ligand) and metal complexes were analyzed by three fungal and four bacteria pathogens. The ligand has no activity against Aspergillus terreus, but nickel, copper and cobalt chloride complexes showed good activity against Aspergillus terreus. On anti-bacterial activity compare to ligands and other metal (II) complexes the cobalt (II) complex revealed greater inhibition effect on selected bacteria.
