Abstract

Binding of the D-amino acids D-5-hydroxytryptophan (D-5-HTP) and D-dihydroxyphenylalanine (D-DOPA) to high affinity sites for serotonin (5-HT) and dopamine (DA) was studied in bovine striatum. D-5-HT bound to the 5-HT site with affinity in the micromolar range, but showed no appreciable binding at the DA site. D-DOPA showed little binding to either 5-HT or DA receptors.
