Tizanidine
Based on 1 Customer Validation
Tizanidine, a skeletal muscle relaxant, is an orally effective central α2-adrenoceptor agonist (IC50 = 6.9 nmol). Tizanidine primarily exerts muscle relaxation effects by inhibiting the release of excitatory amino acids (glutamate and aspartate) from the presynaptic terminals of spinal cord interneurons. Tizanidine has anti-injury activity and can inhibit gastrointestinal (GI) transport. Tizanidine can inhibit the proliferation, migration, and invasion of lung cancer cells and induce cell apoptosis by upregulating Nischarin and inhibiting the AKT and Wnt3a/β-catenin signaling pathways. Tizanidine can be used to treat spasticity caused by diseases such as multiple sclerosis (MS), stroke, and spinal cord injury (SCI).

α adrenergic receptor |
Tizanidine is mainly metabolized by cytochrome CYP1A2 and resultes in time- and NADPH-dependent substrate consumption with a half-life of 50 min in human liver microsomes[2].
Tizanidine (20 μM, 0-72 h) inhibits the proliferation, migration and invasion of A549 cells, and induces apoptosis through the regulation of AKT and Wnt3a/β-catenin pathways mediated by Nischarin[3].

-
Concentration:20 μM
-
Incubation Time:24 h
-
Result:Decreased Bcl-2 expression, while simultaneous expression of Bax was increased.
Significantly increased the expression of Caspase-3.
Was no change in the expressions of AKT and mTOR, while in the phosphorylated forms p-AKT and p-mTOR decreased.
Decreased expressions of P70 and Cyclin D1.
Led to a significant decrease in the levels of Wnt3a and β-catenin, which suggested that Wnt3a/β-catenin pathway was inactivated.
Down-regulated Nischarin.

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.
