In the present work, new indole derivatives, i.e., 5-[N,N-di alkyl amino alkoxy] azaindole 2,3- di-one derivatives, are synthesized and characterized. These compounds were subjected to acute toxicity and then screened for antiepileptic activity on maximal electroshock seizure (MES) model in albino Wistar rats. In that study 5-[2-dimethyl amino ethoxy] Azaindole-3-hydrazone,2-one and 5-[2- dimethyl amino ethoxy] Azaindole 2-one,3-thiothiosemicarbazone(IIIa) showed good antiepileptic activity and less neurotoxicity compared to phenytoin. The purpose of the present study is to investigate the effect of 5-[2-dimethyl amino ethoxy] Indole 2,3- di one and 5-[2-dimethyl amino ethoxy] Azaindole 2-one,3-thiosemicarbazone(IIIa) derivatives on biogenic amines concentrations in rat brain after induction of seizures by MES method. The aim of study was relationship between seizure activities and altered the monoamines such as Noradrenaline (NA), Dopamine (DA), Serotonin (5-HT) in forebrain of rats in MES seizure models. In MES model, study of 5-[2-dimethyl amino ethoxy] Azaindole 3-hydrazone,2-one(Va) and 5-[2-dimethyl amino ethoxy]Azaindole 2-one,3-thiosemicarbazone(IIIa) (100 mg/kg) showed significant restoration of the decreased levels of brain monoamines such as noradrenaline, dopamine, and 5-hydroxytryptamine. Thus, this study suggests that 5-[2-Dimethyl amino ethoxy] Azaindole 3-hydrazone,2-one (V) and 5-[2-dimethyl amino ethoxy] Azaindole 2-one,3-thiosemicarbazone (IIIa) increased the monoamines on rat brain, which may decrease the susceptibility to MES-induced seizure in rats. |
