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.

Cell Viability Assay[1]

Cell Line: Neuro-2a cells and SH-SY5Y cells
Concentration: 0-500 µM
Incubation Time: 24 or 48 h
Result: Induced neurotoxicity, caused cytotoxicity in both Neuro-2a cells and SH-SY5Y cells in a concentration dependent manner. EC50=111 µM for 24 h incubation and 109 µM for 48 h incubation in the Neuro-2a cells; EC50=118 µM for 24 h incubation and 107 µM for 48 h incubation in the SH-SY5Y cells.

Oxidopamine hydrobromide can be used in animal modeling to construct Parkinson's syndrome models. Oxidopamine hydrobromide (5 μg/2 μL, unilaterally injected into the right striatum) induces degeneration of dopaminergic neurons in substantia nigra of rats[2].

Induction of Parkinson's disease model[5][6]
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.

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline
