3-Methoxy-L-tyrosine monohydrate Chemical Properties, Uses, Production
Chemical Properties
Brown Solid
Uses
3-O-Methyl-L-DOPA is the major metabolite of L-DOPA via catechol O-methyltransferase (COMT). 3-Methoxy-L-tyrosine is neither a substrate for nor an inhibitor of L-amino acid decarboxylase activity. Inhibition of COMT enhances the anti-Parkinson activity of L-DOPA.
Biological Activity
