title: Metabolic O-demethylation of the psychotomimetic amine 1-(2, 5-dimetroxy-4-methylphenyl)-2-aminopropane.
abstract: In an effort to more fully characterize the metabolic fate of the psychotomimetic amine (1-(2, 5-dimethoxy-4-methylpheny.)-2-aminopropane (DOM, STP), the formation of the two possible monophenols and the p-hydroquinone metabolites of the parent drug by 10,000 X g supernatent fractions of rabbit liver homogenates has been investigated. All three metabolites have been fully characterized and quantitatively estimated by chemical ionization mass spectrometry with the aid of deuterium enriched compounds. The stereochemical course of the mono-O-demethylation reactions has been shown to proceed with enantiomeric enrichment of the S-aminophenols. The mechanistic implications concerning the mode of action of the parent drug and metabolic O-demethylation are discussed.
