Dehydrozingerone(DHZ),isolated from ginger(Zingiberofficinale),
is an unsaturated derivative of the natural produc tzingerone.DHZ
exert santi-oxidant[1,2],free radical scavenging[3],andanti-
tumour activities[4,5],and also inhibits wound healing[6]and
lipid peroxidation[7].Metabolic roles for DHZ have been proposed,
but the molecular mechanisms underlying these effects remain
unclear.
