| Common Name | 3-Methoxy-4-hydroxyphenylglycolaldehyde |
|---|
| Description | 3-Methoxy-4-hydroxyphenylglycolaldehyde, also known as 4-hydroxy-3-methoxy mandelaldehyde, 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. 3-Methoxy-4-hydroxyphenylglycolaldehyde is an extremely weak basic (essentially neutral) compound (based on its pKa). 3-Methoxy-4-hydroxyphenylglycolaldehyde is the monoamine oxidase (MAO) aldehyde metabolite of metanephrine. 3-Methoxy-4-hydroxyphenylglycolaldehyde exists in all living organisms, ranging from bacteria to humans. Within humans, 3-methoxy-4-hydroxyphenylglycolaldehyde participates in a number of enzymatic reactions. In particular, 3-methoxy-4-hydroxyphenylglycolaldehyde can be biosynthesized from normetanephrine; which is mediated by the enzyme amine oxidase [flavin-containing] a. In addition, 3-methoxy-4-hydroxyphenylglycolaldehyde can be biosynthesized from metanephrine through the action of the enzyme amine oxidase [flavin-containing] a. Metanephrine is an O-methylated metabolite formed by catechol-O-methyltransferase (COMT) from epinephrine. In humans, 3-methoxy-4-hydroxyphenylglycolaldehyde is involved in the metabolic disorder called the monoamine oxidase-a deficiency (mao-a) pathway. Outside of the human body, 3-Methoxy-4-hydroxyphenylglycolaldehyde has been detected, but not quantified in, several different foods, such as chervils, kai-lans, calabash, custard apples, and tea. This could make 3-methoxy-4-hydroxyphenylglycolaldehyde a potential biomarker for the consumption of these foods. Catecholamines are substantially increased during stress, exercise or smoking and could result in clinically important platelet activation if their action was not rapidly regulated. Catecholamines play an important role in platelet activation and aggregation, epinephrine being the most potent one. The inhibitory effects of methoxy phenolic derivatives on epinephrine-induced platelet aggregation may possibly be attributed to their free radical scavenging properties. There is substantial evidence to conclude that an internal rapid autoregulation of epinephrine-induced platelet aggregation, caused by its metabolic degradation products, takes place in vivo. |
