What is LEVODOPA RELATED COMPOUND A (50 MG) (3-(3,4,6-TRIHYDROXYPHENYL)-ALANINE)?

The Uses of LEVODOPA RELATED COMPOUND A (50 MG) (3-(3,4,6-TRIHYDROXYPHENYL)-ALANINE)

6-Hydroxy-L-DOPA 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.
