• Description: Applications Labelled 3-O-Methyl-L-DOPA (M303815). 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.References Soares-da Silva, P., et al.: Brain Res., 863, 293 (2000), Deleu, D., et al.: Clin. Pharmacokinet., 41, 261 (2002),
