Abstract

[6]-Gingerol, a naturally occurring plant phenol, is one of the major components of fresh ginger (Zingiber officinale Roscoe, Zingiberaceae) and has diverse pharmacologic effects. Here, we describe its novel anti-oxidant, anti-apoptotic, and anti-inflammatory activities in vitro and in vivo. In vitro, pre-treatment with [6]-gingerol reduced UVB-induced intracellular reactive oxygen species levels, activation of caspase-3, -8, -9, and Fas expression. It also reduced UVB-induced expression and transactivation of COX-2. Translocation of NF-kappaB from cytosol to nucleus in HaCaT cells was inhibited by [6]-gingerol via suppression of IkappaBalpha phosphorylation (ser-32). Examination by EMSAs and immunohistochemistry showed that topical application of [6]-gingerol (30 microM) prior to UVB irradiation (5 kJ/m(2)) of hairless mice, also inhibited the induction of COX-2 mRNA and protein, as well as NF-kappaB translocation. These results suggest that [6]-gingerol could be an effective therapeutic agent providing protection against UVB-induced skin disorders.
