L-DOPA (Levodopa) is an orally active metabolic precursor of neurotransmitters dopamine. L-DOPA can cross the blood-brain barrier and is converted into dopamine in the brain. L-DOPA has anti-allodynic effects and the potential for Parkinson's disease.

Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.
L-DOPA can be used to create movement disorder models. In adult common marmosets, after oral administration of L-DOPA (20 mg/kg, 5 mg/kg), the Tmax in plasma is 30 minutes, and the Tmax in striatal extracellular fluid (ECF) is 60-90 minutes. The mean Cmax of L-DOPA in plasma is 20.3 μM, while the mean Cmax in striatal ECF is 442.9 nM, representing about 2.2% of the plasma level[6].
Administration: 20 mg/kg • ip • once daily for 21 days
(2) Injection volume is 10mL/kg body weight.

Amphiregulin (Areg) is highly expressed in the levodopa‐induced dyskinesia 6‐OHDA (4 μg; 4 weeks) Parkinson's disease mouse model. The Parkinson's disease group treated with a daily 12 mg/kg of levodopa for 15 days developed dyskinetic movement. On western blotting, this group further showed a significant increase of Amphiregulin protein expression relative to the Parkinson's disease group injected with normal saline only .
