DescriptionVanylglycol, also known as 3-Methoxy-4-hydroxyphenylethyleneglycol (MHPG), belongs to the class of organic compounds known as methoxyphenols. Methoxyphenols are compounds containing a methoxy group attached to the benzene ring of a phenol moiety. It is synthesized from endogenous epinephrine and norepinephrine in vivo. It is found in brain, blood, CSF, and urine, where its concentrations are used to measure catecholamine turnover. Catecholamines play an important role in platelet activation and aggregation, epinephrine being the most potent one. Vanylglycol and pyrocatechol can be biosynthesized from 3,4-dihydroxyphenylglycol and guaiacol; which is catalyzed by the enzyme catechol O-methyltransferase. Vanylglycol is a O-methylated metabolite of normetanephrine. In humans, vanylglycol is involved in the metabolic disorder called tyrosinemia in newborns. Alcohol consumption increases the level of vanylglycol in urine and CSF. Vanylglycol is found normally in urine, in plasma and cerebrospinal fluid. Outside of the human body, vanylglycol has been detected, but not quantified in several different foods, such as blackcurrants, chinese bayberries, elderberries, oriental wheats, and poppies.
