Abstract
Antiepileptic drug (Preg) and neurotransmitters (Gpn, Gly, Asp, Glu, Ser, GABA and Ade) were used to synthesis a series of ternary Cu2+ complexes. Surface morphology and chemical composition of the complexes were using studied SEM and EDX spectra. Purity, molecular weight and formulae of the complexes were determined from GC-MS spectra and elemental analysis. XRD data and N-Treor implemented in Expo2014 computer program reveal monoclinic crystal system with space group P1 2/c 1 and P 1 21 1 of the complexes. IR spectra exhibited that Preg, Gpn and GABA coordinated to the Cu2+ as monodentate ligand through COOH whereas the amino acids bonded through the -NH2, COO- groups. UV-Vis spectra and magnetic moment values indicated pseudo tetrahedral stereochemistry. ESR spectra showed that the complexes have isotropic and axial structures with d(x2-y2) ground state. TGA, DTG and DTA confirm the suggested structure and mechanism for thermal decomposition was suggested. Kinetic and thermodynamic parameters were calculated using Coats-Redfern equation. The complexes [Cu(Preg)(Ser)Cl] and [Cu(Preg)(Ade)Cl-2] showed greater anticonvulsant activity compared against PTZ-induced seizures in male Albino mice. Recorded latency time for the complexes [Cu(Preg)(Ser)Cl] and [Cu(Preg)(GABA)(OH)Cl]center dot 2H(2)O was longer than that recorded with Preg indicating higher anticonvulsant effect.
