Epilepsy is a chronic
neurological disorder characterized by an abnormal, spontaneous, and synchronized neuronal hyperactivity. Therapeutic approaches for controlling epileptic
seizures are associated with pharmacoresistance and side effects burden. Previous studies reported that different natural products may have neuroprotector effects.
Sakuranetin (SAK) is a
flavanone with
antiparasitic, anti-inflammatory, antimutagenic,
antiallergic, and
antioxidant activity. In the present work, the effect of SAK on
seizures in a model of
status epilepticus induced by
bicuculline (
BIC) in mice was evaluated. Male Swiss mice received an intracerebroventricular injection (i.c.v.) of SAK (1, 10, or 20 mg/kg-SAK1, SAK10, or SAK20). Firstly, animals were evaluated in the open field (OF; 20 min), afterwards in the elevated plus maze (EPM) test (5 min). Next, 30 min prior the administration of
BIC (1 mg/kg), mice received an injection of SAK (1 or 10 mg/kg, i.c.v.) and were observed in the OF (20 min) for
seizures assessment. After behavioral procedures, immunohistochemical analysis of c-Fos was performed. Our main results showed that the lowest doses of SAK (1 and 10 mg/kg) increased the total distance traveled in the OF, moreover protected against
seizures and death on the
BIC-induced
seizures model. Furthermore, SAK treatment reduced neuronal activity on the dentate gyrus of the
BIC-treated animals. Taken together, our results suggest an
anticonvulsant effect of SAK, which could be used for the development of
anticonvulsants based on natural products from herbal source.
