Dihydrocapsaicin effectively mitigates cerebral ischemia-induced pathological changes in vivo, partly via antioxidant and anti-apoptotic pathways.

Ischemic stroke occurs when there is a sudden blockage of cerebral blood flow. This condition is a major cause of mortality, especially in low-income countries, and its incidence is dramatically increasing. Therapeutic strategies against stroke are therefore required. The present study explored the effects of dihydrocapsaicin on neuronal loss, brain infarct volume, and antioxidants in a rat model of permanent occlusion of the right middle cerebral artery (Rt.MCAO). Male Wistar rats received dihydrocapsaicin intraperitoneally for 7 days after permanent occlusion of their right middle cerebral artery (Rt.MCAO). Then, the brain infarct volume, neuronal density, and antioxidant and anti-apoptotic activities in the cortex and hippocampus were determined at the end of the study. Dihydrocapsaicin treatment was found to significantly improve neuronal density, decrease infarct volume, reduce MDA elevation, improve CAT and SOD activities, decrease the density ratio of Bax and caspase-3, and increase the density ratio of Bcl-XL to β-actin in the cerebral cortex and hippocampus. The present study suggests that dihydrocapsaicin effectively mitigates cerebral ischemia-induced pathological changes in vivo, partly via antioxidant and anti-apoptotic pathways.
