3-O-Methyl carbidopa

Produit contrôlé

CAS : 85933-19-3

3-O-Methyl carbidopa is a metabolite of L-3,4-dihydroxyphenylalanine that is used as a drug in the treatment of Parkinson's disease. 3-O-Methyl carbidopa is a racemic mixture of two stereoisomers that have different chemical properties. The (+) form is more active and has been shown to be more potent than the (-) form. Analysis of this compound by magnetic resonance spectroscopy (NMR) at different magnetic fields showed that it has six distinct resonances: three from the protonated molecule and three from the deprotonated molecule. The proton nmr spectrum showed peaks at 2.02 ppm (D1), 2.81 ppm (D2), 3.84 ppm (D3), 4.07 ppm (D4), 4.28 ppm (D5), and 4.53 ppm (D6). These peaks correspond to resonances for protons
