dopamine receptor

MPTP hydrochloride is a precursor of MPP+, a dopamine neurotoxin with blood-brain barrier permeability. MPTP hydrochloride is toxic to dopaminergic neurons, which can lead to Parkinson's disease, and is widely used in the construction of animal models of Parkinson's disease.

L-DOPA (Levodopa) is an amino acid precursor of dopamine with antiparkinsonian properties. It is a prodrug converted to dopamine by DOPA decarboxylase and can cross the blood-brain barrier. In the brain, levodopa is decarboxylated to dopamine, stimulating dopaminergic receptors and compensating for depleted endogenous dopamine in Parkinson's disease. To ensure adequate concentrations reach the central nervous system, levodopa is administered with carbidopa, a decarboxylase inhibitor that does not cross the blood-brain barrier, reducing peripheral decarboxylation and increasing CNS dopamine delivery.

Oxidopamine hydrobromide (6-OHDA hydrobromide) is a neurotransmitter dopamine antagonist.

Haloperidol (Serenace) is a highly potent neuroleptic by relieving nervous through the depression of nerve function. In addition, haloperidol has shown about 50-fold efficacy than chlorpromazine, another antipsychotic drug. Haloperidol has some potencies in the treatment of delusions and hallucinations. Its effects are primarily attained through blocking dopamine receptors in the mesocortex and limbic system.

Oxidopamine hydrochloride (6-Hydroxydopamine hydrochloride) is an neurotransmitter dopamine antagonist.
