Biochem/physiol Actions

Azumolene, a more water-soluble analog of dantrolene, is a potent inhibitor of sarcoplasmic reticulum (SR) ryanodine receptor (RyR) that inhibits skeletal muscle SR Ca2+ release. Azumolene is a direct acting skeletal muscle relaxant that induces effective blockade of skeletal muscle RyR1.

Mechanical ventilation (MV) is a life-saving intervention for patients in respiratory failure. However, prolonged MV causes the rapid development of diaphragm muscle atrophy, and diaphragmatic weakness may contribute to difficult weaning from MV. Therefore, developing a therapeutic countermeasure to protect

Following long-duration ventricular fibrillation (LDVF), reinitiation of ventricular fibrillation (VF) poses a major challenge during resuscitation. Ryanodine receptor 2 (RyR2) becomes dysfunctional following VF. The relationship between LDVF, RyR2 modulation, and ventricular refibrillation, as well as the role of RyR2 phosphorylation
