Use of Benserazide hydrochloride

Benserazide Hydrochloride is a peripherally-acting aromatic L-amino acid decarboxylase (AAAD) or DOPA decarboxylase inhibitor.Target: DOPA decarboxylaseBenserazide is commonly used for Parkinson's disease in combination with L-DOPA as a peripheral aromatic L-amino acid decarboxylase (AADC) inhibitor. Administration of 5, 10 and 50 mg/kg benserazide to 6-OHDA-lesioned rats showed an identical increase in exogenous L-DOPA-derived extracellular DA levels, the time to reach the peak DA levels were significantly prolonged by benserazide dose-dependently. The AADC activity in the denervated striatal tissues showed a significant decrease by 10 mg/kg and 50 mg/kg benserazide. These results suggest that benserazide reduces the central AADC activity in the striatum of rats with nigrostriatal denervation, which leads to changes in the metabolism of exogenous L-DOPA [1].

Adenosine A1 receptor stimulation reduces D1 receptor-mediated GABAergic transmission from striato-nigral terminals and attenuates l-DOPA-induced dyskinesia in dopamine-denervated mice

Exp. Neurol. 261 , 733-43, (2014)

γ-Aminobutyric acid A receptor (GABAAR)-mediated postsynaptic currents were recorded in brain slices from substantia nigra pars reticulate neurons. The selective adenosine A1 receptor (A1R) antagonist...

Brain 137(Pt 8) , 2287-302, (2014)

Dopamine midbrain neurons within the substantia nigra are particularly prone to degeneration in Parkinson's disease. Their selective loss causes the major motor symptoms of Parkinson's disease, but th...

L-DOPA-induced dyskinesia in a rat model of Parkinson's disease is associated with the fluctuational release of norepinephrine in the sensorimotor striatum.
