4-hydroxyalternariol

4-Hydroxyalternariol is the fully demethylated tetraphenol analogue of the benzopyranone graphislactones. Hydroxyalternariol was isolated as a major co-metabolite of a graphislactone A-producing fungus. Hydroxyalternariol has not previously been available for study and no bioactivity has been reported to date.

4-Hydroxyalternariol is soluble in ethanol, methanol, DMF or DMSO.
