4-hydroxybenzyl alcohol (4-HBA), one of the phenolic constituents found in many herbal medicinal plants, exhibits beneficial effects in neurological disorders. In the present study, we evaluated 4-HBA's role in transient cerebral ischemia and its potential mechanism. Pre-treatment with 4-HBA (50,100 mg/kg) significantly reduced the cerebral infarct size and improved the neurological symptoms. Morphological examinations showed 4-HBA reduced the number of degenerated neurons. Oxidative stress was evaluated superoxide dismutase (SOD) activity and malondialdehyde (MDA) level. Anti-oxidative mechanisms were studied by Immunofluorescence staining and western immunoblot analysis. 4-HBA increased the expression of NAD(P)H: quinone oxidoreductase1 (NQO1) and ultimately inhibited oxidative stress. In addition, we evaluated the time course expression of NQO1, which was upregulated in the ischemic brain beginning at 1 h. Taken together, these results suggested that 4-HBA ameliorated cerebral injury in rats, This neuroprotective effect is likely related to its antioxidant activities.
