MedChemExpress - Model Dantrolene sodium hemiheptahydrate - 24868-20-0

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[1][2][3][4][5][6][7][8][9][10][11].

Description：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.

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：Dantrolene (5-20 mg/kg, i.v.) sodium hemiheptahydrate exhibits cardioprotective effects in a rat model of Digoxin (HY-B1049)-induced cardiotoxicity[4]. Dantrolene (5-10 mg/kg, i.p.) sodium hemiheptahydrate attenuates spinal cord inflammation in mice with experimental autoimmune encephalomyelitis (EAE) [5]. Dantrolene (5 mg/kg, intranasal or subcutaneous, 3 times per week) sodium hemiheptahydrate improves cognitive dysfunction in 5XFAD Alzheimer's disease (AD) mice [6].
