On the basis of previous work showing that flavonoids structurally related to quercetin are neuroprotective for cells in culture, this work was directed towards determining if several flavonoids (quercetin, fisetin and catechin) could acutely and by an intraperitoneal (IP) route reach significant cerebral concentrations and either prevent or facilitate recovery from a brain lesion induced by focal...
Oxidative stress is implicated in the pathogenesis of cerebral ischemia injury, and the flavonoids have shown to be neuroprotective in experimental models of cerebral ischemia. Previously, we have shown that an aqueous preparation of quercetin did not reach the brain while a liposomal preparation produced measurable cerebral amounts of quercetin that reduced significantly the cerebral damage provoked...
