Edaravone (formerly known as Radicut; MCI-186; NCI-C03952; NSC 12; Norantipyrine; Norphenazone; trade name: Radicava) is a novel and potent free radical scavenger that has been used clinically to reduce the neuronal damage following ischemic stroke. In May 2017, Edaravone was approved by FDA to treat patients with amyotrophic lateral sclerosis (ALS). Edaravone inhibits MMP-9-related brain hemorrhage in rats treated with tissue plasminogen activator. It was approved by FDA in May 5th 2017 for the treatment of amyotrophic lateral sclerosis (ALS). Edaravone reduces apoptosis and necrosis caused by glutamate. Pretreatment of edaravone (500 μM) reverses these changes to approximately normal levels.
ln Vitro |
Edaravone has effects on glutamate toxicity that are both therapeutic and preventative. Edaravone pretreatment decreased glutamate's toxicity to SGN. Edaravone lessens necrosis and apoptosis brought on by glutamate. These alterations were reverted to near-normal levels by pretreatment with 500 μM edaravone. Edaravone's protective action against glutamate-induced SGNs cell apoptosis is associated with the Bcl-2 protein family and the PI3K/Akt pathway [4].

ln Vivo |
In cerebral ischemia, edaravone reduces neuronal damage and prevents endothelium damage to have neuroprotective effects. The helpful NOS that can save an ischemic stroke is increased when eNOS is present, but nNOS and iNOS—the toxic NOS—are decreased when edaravone is present. Pretreatment with edaravone decreases hemorrhagic episodes and post-reperfusion cerebral edema brought on by thrombolytic therapy [1]. The infarct size was greatly reduced by edaravone; rats in the edaravone group had an average infarct size of 227.6 mm3, which was significantly smaller than rats in the control group (264.0 mm3). Additionally, the post-ischemic bleeding volume was decreased by edaravone therapy (53.4 mm3 in edaravone-treated rats against 53.4 mm3 in the control group). 176.4 millimeters). Furthermore, rats treated with edaravone had a decreased ratio of bleeding volume to infarct volume (23.5%) compared to rats not treated (63.2%) [2]. The corpus callosum, germinal matrix, and cerebral cortex of rats given Edaravone (20 mg/kg) showed decreased astrocyte activity (glial fibrillary acidic protein) and apoptotic cells (caspase-3) [3].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
