3,4-Methylenedioxymethamphetamine (MDMA, Ecstasy) is excreted in human urine mainly as conjugates of its metabolites 3,4-dihydroxymethamphetamine (DHMA) and 4-hydroxy-3-methoxymethamphetamine (HMMA). The glucuronidation kinetics of HMMA showed high capacities, but also high K(m) values, unlikely to be reached after recreational user's doses.

A continuous spectrophotometric method for the rapid determination of diphenolase activity of tyrosinase is described. It uses 3,4-dihydroxymandelic acid (DOMA) as the substrate of tyrosinase and measures the final product, 3,4-dihydroxybenzaldehyde (DOBA). The spectrum of this product shows a bathochromic

Mushroom tyrosinase, which is known to convert a variety of o-diphenols into o-benzoquinones, has been shown to catalyse an unusual oxidative decarboxylation of 3,4-dihydroxymandelic acid to 3,4-dihydroxybenzaldehyde [Sugumaran (1986) Biochemistry 25, 4489-4492]. The mechanism of this reaction was re-investigated. Although

Pseudomonas putida F6 was found to metabolize p-hydroxyphenylacetic acid through 3,4-dihydroxyphenylacetic acid, 3,4-dihydroxymandelic acid, and 3,4-dihydroxybenzaldehyde. Cell extracts of P. putida F6 catalyze the NAD(P)H-independent hydroxylation of p-hydroxyphenylacetic acid to 3,4-dihydroxyphenylacetic acid which is further oxidized to 3,4-dihydroxymandelic acid. Oxidation

Pre-synaptic endings of the sympathetic nervous fibers control the metabolism of catecholamines, particularly inactivating norepinephrine after its neuronal recapture. The present study was carried out to investigate this segment of the metabolism of catecholamines through measurements of DHPG, DOMA and
