Dantrolene sodium hemiheptahydrate  (Synonyms: Dantrolene sodium hydrate)

Cat. No.: HY-12542A Purity: 99.79%
SDS COA Handling Instructions Technical Support

Dantrolene sodium hemiheptahydrate is an orally active, non-competitive glutathione reductase inhibitor with a Ki of 111.6 μM and an IC50 of 52.3 μM. Dantrolene sodium hemiheptahydrate is also a calcium channel protein inhibitor. Dantrolene sodium hemiheptahydrate inhibits the release of Ca2+ from RyR1 and RyR3, which can be beneficial in a variety of pathologies caused by disruptions in calcium homeostasis (e.g., stroke, ischemia/reperfusion injury, and neurodegenerative diseases). Dantrolene sodium hemiheptahydrate offers relief of muscle spasms, malignant hyperthermia, and antitoxic, antipyretic, and anti-inflammatory properties.

Dantrolene sodium hemiheptahydrate is also a calcium channel protein inhibitor. Dantrolene sodium hemiheptahydrate inhibits the release of Ca2+ from RyR1 and RyR3, which can be beneficial in a variety of pathologies caused by disruptions in calcium homeostasis (e.g., stroke, ischemia/reperfusion injury, and neurodegenerative diseases). Dantrolene sodium hemiheptahydrate offers relief of muscle spasms, malignant hyperthermia, and antitoxic, antipyretic, and anti-inflammatory properties[1][2][3][4][5][6][7][8][9][10][11].

In Vitro

Dantrolene (50 μM) sodium hemiheptahydrate alleviates malignant hyperthermia by preventing overactive Ca2+ release by increasing the affinity of ryanodine receptor (RyR) for Mg2+ in rat skin fibers[2].
Dantrolene (30 μM, 1 h-3 days) sodium hemiheptahydrate ameliorates the impairment of neurogenesis and synaptogenesis, in association with restoring intracellular Ca2+ homeostasis and physiological autophagy, cell survival and proliferation in induced pluripotent stem cells derived from patients with Alzheimer's disease [3].
Dantrolene (40 μM, 12 h) sodium hemiheptahydrate enhances the protective effect of hypothermia on cerebral cortex neurons, including improved morphology, increased survival and mitochondrial membrane potential, decreased intracellular reactive oxygen species, cytoplasmic histone-associated DNA fragmentation and apoptosis[7].

In Vivo:

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

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
