Application

L-3,4-Dihydroxyphenylalanine methyl ester hydrochloride has been used:
  • in treating 6-hydroxydopamine induced lesions mice serotonin neurons
  • in tyrosinase activity in B16F10 skin melanoma cells
  • to test its neuroprotective effect in mesencephalic neurons

Biochem/physiol Actions

L-3,4-Dihydroxyphenylalanine methyl ester is a precursor to L-DOPA that crosses the blood-brain barrier. Antiparkinsonian agent L-DOPA methyl ester elicits antitumor functionality in leukemia and melanoma.

Levodopa remains the most effective drug in the treatment of Parkinson's disease. However, long-term administration of levodopa induces motor complications, such as levodopa-induced dyskinesia. The mechanisms underlying levodopa-induced dyskinesia are not fully understood. In this study, we prepared levodopa methyl

Dopamine (DA) is required for motor function in vertebrate animals including humans. The striatum, a key motor control center, receives a dense DA innervation and express high levels of DA D1 receptors (D1Rs) and D2 receptors (D2Rs). Other brain areas

The role of dopaminergic transmission on striatal mRNA levels of regulators of G protein signalling proteins RGS 2-12 was evaluated by quantitative in situ hybridisation. A single injection of L-dopa (50 mg/kg i.p.) significantly increased the RGS2 mRNA level (by
