Product Information

Riluzole AI Summary

Riluzole exhibits a diverse range of bioactivities, indicating potential therapeutic applications across multiple domains. It functions as a sodium channel blocker with an IC50 of 4730 nM and a voltage-gated Ca2+ channel blocker in rat brain synaptosomes with an IC50 of 0.0 nM, showing potent inhibition of K+-evoked and veratridine-induced glutamate release. Additionally, Riluzole protects against seizures and has neuroprotective activity, demonstrated by efficacy in rat models of glutamate-induced convulsions (ED50 of 3.2 mg/kg) and focal stroke (effective at 4.0 mg/kg and 30.0 mg/kg). The compound shows considerable metabolic stability, liver enzyme modulation, and potential for therapeutic applications in neuroprotection and stroke. It has a partition coefficient (logD7.4) of 3.43, high plasma protein binding of 97.13%, and demonstrates moderate lipophilicity (LogP 3.2). Additionally, it interferes with various cellular processes, including mitochondrial function, NFkB signaling, and Lamin A splicing, and inhibits several enzymes like BSEP (IC50 139000 nM) and human UGT1A1. In terms of antibacterial and antifungal activity, Riluzole shows efficacy against Escherichia coli, Enterococcus faecalis, Staphylococcus aureus, and several Candida species. It also demonstrates antivirals by inhibiting SARS-CoV-2 3CL-Pro protease and virus-induced cytotoxicity in VERO-6 cells. Moreover, Riluzole has cytotoxic effects in some cell lines but displays neuroprotective properties against excitotoxic and oxidative stress in neuronal cells. Its high aqueous solubility, moderate passive permeability, and good liver microsomal stability underscore its potential as a drug candidate. Overall, Riluzole’s broad bioactivity profile underscores its potential for therapeutic development in treating neurological disorders, infectious diseases, and metabolic conditions..

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO stock solution to 400 µL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 µL Tween 80 and mix well until fully clarified.

3) Add 450 µL Saline,PBS or ddH₂O and mix thoroughly until a homogeneous solution is obtained.
