Hydantoic acid Usage And Synthesis

Uses

N-(Aminocarbonyl)-3-methoxy-O,α-dimethyl-L-tyrosine is an intermediate used in the synthesis of (S)-(-)-Carbidopa (C175985), which is a peripheral decarboxylase inhibitor that is commonly used in combination with L-DOPA (D533751) for treatment of Parkinsonism. S(-)-Carbidopa ( has also been shown to prolong the elimination half-life of L-DOPA from blood plasma and skeletal muscle.
