Synthesis, Characterisation and Biological Evaluation of Nalidixic Acid Metal Complexes

JASEM Front Page
Abstract:
Metalcomplexes of Nalidixic acid such as [Cu(NDX)2].2H2O, [Zn(NDX)2].2H2O, [Ni(NDX)2].6H2O, and [Fe(NDX)2(H2O)Cl].5H2O have been synthesized and characterised by elemental analysis, IR ,UV-Visibe, ESR, NMR,XRD spectrscopic techniques. The results of elemental analysis show that two molecules of the tioconazoledrug are attached per metal ion. Thermal analysis was studied by TGA, DSC method. Morphological studies were carried out by scanning electron microscopic method. Furthur the complexes were screened for their antimicrobial property. The results of elemental analysis show that two molecules of thetioconazole drug are attached per metal ion. From the spectral studies a square planar geometry was proposed for the copper complex. Tetrahedral geometry for zinc and nickel complex and octahedral geometry for iron complex.In conclusion, prepared complexes showed enhanced biological activities than the parent drug that might be of interest for future research.

Keywords:Antimicrobial , geometry, ligand, metal complexes, nalidixic acid.
