RYR-CALSTABIN INTERACTION 1PC X 10MG (C15-1304-084)

General description

A cell-permeable, orally active benzothiazepine derivative that effectively blocks leaky intracellular calcium release by preventing the dissociation/depletion of calstabin from the ryanodine receptor (RyR) complex due to receptor modifications, such as oxidation, S-nitrosylation, PKA-mediated hyperphosphorylation, or mutation (complete blockage of 1 mM tetracaine-induced leakage in murine RyR2 S2808D^+/+ myocytes at 1 µM). Oral administration in mice (75 mg/kg/day via drinking water) is shown to prevent stress-induced cognitive dysfunction by stabilizing RyR2-calstabin-2 (FKBP12.6) interaction in brain of stressed animals. Likewise, s.c. administration (2.5 µg/0.25 µL/h/animal; by s.c. via neck dorsal surface osmotic pump implant) is reported to maintain mice exercise capacity by stabilizing RyR1-calstabin-1 (FKBP12) interaction in skeletal muscle following intensive exercise regimes. Also demonstrated to exhibit in vivo efficacy in restoring normal cardiac function in mice with R2474S (5 mg/kg/h; by s.c. via osmotic pump) or S2808D (20 mg/kg/day; by s.c. via osmotic pump) RyR2 mutation.
