title: In vitro stereoselective metabolism of the psychotomimetic amine, 1-(2,5-dimethoxy-4-methylphenyl)-2-aminopropane. An apparent enantiomeric interaction.
abstract: The stereoselective metabolism [R/S (metabolized) less than 1] of the psychotomimetic amine (R,S)-1-(2,5-dimethoxy-4-methylphenyl)-2-aminopropane in 10 000g rabbit liver homogenate supernatant and 100 000g microsomal fractions has been demonstrated with the aid of the chiral reagent (S)-N-pentafluorobenzoylprolyl-1-imidazolide and GLC analyses. In contrast to the enantiomeric discrimination observed with racemic amine, the individual isomers were metabolized at approximately the same rate. This apparent enantiomeric interaction illustrates the fact that racemates should be viewed as unique chemical species with pharmacodynamic and toxicologic profiles potentially different from the individual antipodes.
