D-DOPA is an enantiomer of the dopamine precursor L-DOPA . It can be converted to L-DOPA via sequential oxidation and transamination, which are mediated by D-amino acid oxidase (DAAO) and DOPA transaminase, respectively, in rat kidney homogenates.1 It reduces the number of dopaminergic neurons in primary rat embryonic mesencephalic cultures in a concentration-dependent manner.2 Intraventricular administration of D-DOPA (200 µg/animal) increases striatal dopamine levels in rats.3 D-DOPA (20 mg/kg, i.p.) induces contralateral turns in a rat model of Parkinson's disease induced by 6-OHDA .4
