• In this study, we investigated the protective effect of l -homocarnosine, l -carnosine, and anserine (HCA) on seizure-induced brain injuries. We evaluated the protective effect of HCA on brain oxidative damage in a pentylenetetrazole (PTZ)-induced epilepsy model using ovariectomized (OVX) rats. The experimental groups were as follows: group I, sham; group II, sham + PTZ; group III, sham + HCA + PTZ; group IV, OVX; group V, OVZ + PTZ; and group VI, OVX + HCA + PTZ. We determined the levels of lipid peroxidation, glutathione peroxidase (Gpx), reduced glutathione (GSH), catalase, superoxide dismutase (SOD), and thiol in brain hippocampal and cortical tissue. The biochemical markers were significantly altered in the brain tissue of OVX rats. HCA supplementation significantly reduced lipid peroxidation and increased GSH, Gpx, SOD, catalase, and thiol levels in PTZ-treated OVX rats. Rats with an ovariectomy showed a significant protective effect against PTZ through elevation of the latency of generalized tonic–clonic seizures (GTCS). HCA substantially increased minimal clonic seizure and GTCS latency in the OVX–PTZ and sham–PTZ groups. In summary, our experimental data indicate that combined supplementation of HCA substantially increased anticonvulsant activity. Moreover, combined HCA supplementation reduced oxidative damage by decreasing lipid peroxidation and increasing antioxidant levels in the brain of a PTZ-induced seizure rodent model.
