Oxidopamine (6-OHDA) hydrobromide is an antagonist of the neurotransmitter dopamine. Oxidopamine hydrobromide is a widely used neurotoxin and selectively destroys dopaminergic neurons. Oxidopamine hydrobromide promotes COX-2 activation, leading to PGE2 synthesis and pro-inflammatory cytokine IL-1β secretion. Oxidopamine hydrobromide can be used for the research of Parkinson’s disease (PD), attention-deficit hyperactivity disorder (ADHD), and Lesch-Nyhan syndrome.

Background
The chemical structure of
oxidopamine hydrochloride is similar to dopamine (DA), enabling it to compete
with DA for uptake sites and be subsequently taken into cells. Once inside the
cells, oxidopamine hydrochloride can be oxidized and decomposed, generating
reactive oxygen species, which further produce oxygen free radicals through MAO
(monoamine oxidase) or directly cause mitochondrial dysfunction, leading to the
death of dopaminergic neurons.
Specific Modeling Methods
Rats: Sprague-Dawley (SD) • Male • 200-250
g • Administration: 5μg/2μL/site (Oxidopamine hydrochloride for example; HY-B1081) • stereotaxically injected in the fight striatum • single dose.
Note
(1) Lesions were made by the unilateral injection of Oxidopamine hydrochloride (5 μg in 2 μl/site) into the right striatum at the two coordinates: ① AP, ?0.7; L, ?3.0; DV, ?5.5 and 4.5 mm from Bregma. ② AP, ?0.2; L, ?2.6; DV, ?5.5 and 4.5 mm from Bregma. The two coordinates were injected Oxidopamine hydrochloride 10 μg in 4 μl/2 sites.
(2) Oxidopamine hydrochloride was prepared freshly in dark to avoid autooxidation, and was administered using a 5 μl microinjector at a rate of 0.5 μl/min. The syringe was left in place for 5 min before slowly retracting it to allow for toxin diffusion and prevent the toxin reflux.
(3) On the 56th day after the injury, the animals were decapitated under deep halothane anesthesia. Their brains were quickly removed from the skull, rinsed with chilled saline, and tissue samples containing the caudate-putamen head were dissected from both the lesioned and unlesioned striata on ice.
(4) The animals were housed in an environment with a 12-hour light/dark cycle, with the temperature maintained at 22-23°C. They were allowed free access to food and tap water.
Modeling Indicators
Behavioral monitoring: Rats exhibit rotation with a rotation count greater than 210 r/30 min.
Molecular changes: Elevated levels of COX-2, TNF-α mRNA, and COX-2 protein.
Histopathological changes: Chromatin condensation into clumps around the nucleus, along with evident mitochondrial swelling and vacuolation. Induced nigrostriatal nerve terminal lesions. Decreased striatal dopamine levels and reduced number of tyrosine hydroxylase immunoreactive cells in the ipsilateral substantia nigra, accompanied by long-term significant atrophy of remaining dopaminergic neurons.
