The enantiomers of a number of catecholamines, including (alpha S)- and (alpha R)-erythro-alpha-methylepinephrine, were evaluated for their capacity to compete for binding sites in rat forebrain homogenates with [3H]prazosin, a ligand which selectively binds to adrenergic receptors of the alpha 1 subtype. (alpha R)-erythro-alpha-Methylepinephrine is devoid of apparent biological activity, but the activity of the alpha S isomer is substantial. The latter is less active than the endogeneous catecholamines, (R)-norepinephrine and (R)-epinephrine, but the stereospecific competition for [3H]prazosin binding sites by the catecholamine isomers with the beta R configuration is additional evidence that (alpha S)-erythro-alpha-methylepinephrine may be a biologically active metabolite of L-alpha-methyl-3,4-dihydroxyphenylalanine.
