6-Hydroxy-L-DOPA (Levodopa EP Impurity A; Levodopa USP Related Compound A) is the 6-hydroxy derivative of the amino acid L-DOPA (D533751) with neurotoxic properties. Studies show that exogenously administered 6-Hydroxy-L-DOPA is biotransformed by amino acid decarboxylase to the highly potent and catecholamine-selective neurotoxin, 6-Hydroxydopamine. The treatment of 6-Hydroxy-L-DOPA in rats resulted in the stimulation of acetylcholinesterase. | [Uses]
