Estrogens can protect neurons against oxidative stress-induced cell de
ath due to their antioxidant potential, Here, ae report that other aro
matic alcohols with intact phenolic groups and different phenol deriva
tives can also protect neurons against oxidative cell death induced by
glutamate and hydrogen peroxide in vitro. This neuroprotective activi
ty was independent of the time the compound was added before the toxin
. Methylation of the phenolic hydroxyl group led to a decrease or loss
in neuroprotection, Moreover, the tested compounds directly inhibited
peroxidation reactions, suggesting that neuroprotection is mediated b
y their antioxidant properties. (C) 1997 Federation of European Bioche
