What are 6 Hydroxydopamine?
Oxidopamine, also known as 6-hydroxydopamine (6-OHDA) or 2,4,5-trihydroxyphenethylamine, is a neurotoxic synthetic organic compound used by researchers to selectively destroy dopaminergic and noradrenergic neurons in the brain.
How does 6 Hydroxydopamine work?
6-OHDA has two ways of action: it easily forms free radicals and it is a potent inhibitor of the mitochondrial respiratory chain complexes I and IV. The inhibition of respiratory enzymes by 6-OHDA is reversible and insensitive towards radical scavengers and iron chelators with the exception of desferrioxamine.
Does 6-OHDA cross the blood brain barrier?
Similar to dopamine, 6-OHDA does not cross the blood–brain barrier5,6 and its method of administration defines whether central or peripheral catecholaminergic neurons are affected, and therefore which symptoms of Parkinson’s disease are modeled.
What does oxidopamine do?
The main use for oxidopamine in scientific research is to induce Parkinsonism in laboratory animals by lesioning the dopaminergic neurons of the substantia nigra pars compacta, in order to develop and test new medicines and treatments for Parkinson’s disease.
What effect does 6 Hydroxydopamine have on dopamine neurons?
6-Hydroxydopamine and 1-methyl-4-phenyl-1,2,3,6, tetrahydropyridine are neurotoxins that can induce the rapid death of dopaminergic neurons in the substantia nigra pars compacta.
What are the side effects of apomorphine?
Apomorphine injection may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
- nausea.
- vomiting.
- constipation.
- diarrhea.
- headache.
- yawning.
- runny nose.
- weakness.
What is a contraindication for apomorphine?
Apomorphine should generally be avoided in patients with a major psychotic disorder such as those with a history of psychosis or schizophrenia due to the risk of exacerbating psychosis. In clinical studies, hallucinations were reported in clinical trials of both subcutaneous and sublingual apomorphine.
