Abstract:
An imbalance between inhibitory (GABA) and excitatory (Glutamate) neurotransmission contribute to the development of epilepsy. Earlier studies reported that dysregulation of GABA and glutamatergic activities resulted in status epilepticus (SE) and ultimately support the development of temporal lobe epilepsy (TLE), a type of resistant epilepsy. In the earlier work, 2-propanone-1,3,5,5-trimethyl-2-cyclohexen-1-ylidine demonstrated anticonvulsant activity against pentylenetetrazole (PTZ)-induced seizures. Apart from the PTZ-induced TLE, the dysregulation muscaranic receptors and glycine receptors are also widely reported phenomena in the development of temporal lobe epilepsy. Keeping the role of these two receptors in epilepsy, the present work investigated the effect of 2-propanone-1,3,5,5trimethyl-2-cyclohexen-1-ylidine in pilocarpine-induced and strychnine-induced seizure models. Our results demonstrated that 2-propanone-1,3,5,5-trimethyl-2-cyclohexen-1-ylidine significantly delayed the onset of seizure with maximum protection from SE in pilocarpine-induced seizure model. However, the test compound did not revealed any effect on strychnine-induced seizures in mice. Based on these observations, we suggest that 2-propanone-1,3,5,5trimethyl-2-cyclohexen-1-ylidine could be a potential candidate in reduction of SE and treatment of temporal lobe epilepsy (TLE) in future.
