Levetiracetam, an antiepileptic drug has neuroprotective effects on intracranial hemorrhage injury
Publication date: Available online 11 February 2020Source: NeuroscienceAuthor(s): Takahiko Imai, Tomoki Sugiyama, Sena Iwata, Shinsuke Nakamura, Masamitsu Shimazawa, Hideaki HaraAbstractIntracranial hemorrhage (ICH) is a devastating disease that induces hematoma formation with poor neuronal outcome. Levetiracetam (LEV) has been approval for epilepsy seizures. In a previous study, LEV exerted protective effects on cerebral ischemia models; however, the detail effects and the influence of LEV on ICH are still unknown. The aim of this study was to investigate whether oral administration of LEV (50 or 150 mg/kg) has protective...

Sirtuin 6 protects the brain from cerebral ischemia/reperfusion injury through NRF2 activation
In this study, we investigated the effects of SIRT6 overexpression in regulating I/R injury in a mouse cerebral I/R model in vivo and in oxygen-glucose-deprivation/reoxygenation (OGD/R)-stimulated neuro-2a neuroblastoma cells in vitro. We found that cerebral I/R (1 h/24 h) resulted in decreased SIRT6 expression in the cerebral cortex (P < 0.01). SIRT6 overexpression in the brain by in vivo gene transfer enhanced the antioxidant NRF2 signaling (P < 0.05), reduced oxidative stress (P < 0.05), and attenuated cerebral I/R-induced brain tissue damage and neurological deficits (P <â€...

Neuroprotective activity of (1S,2E,4R,6R,-7E,11E)-2,7,11-cembratriene-4,6-diol (4R) in vitro and in vivo in rodent models of brain ischemia
In conclusion, the present study indicates that 4R has a protective effect in rodent ischemic stroke models. Inhibition of ICAM-1 expression and restoration of Akt phosphorylation are the possible mechanisms involved in cellular protection by 4R.
