3-O-Methyl-L-DOPA-d3 Monohydrate

Controlled Product

CAS: 200630-46-2, 586954-09-8

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.
