General Description

A cell-permeable, orally active benzothiazepine 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, hyperphosphorylation, or mutation (complete blockage of 1 mm tetracaine-induced leakage in murine RyR2 S2808D^+/+myocytes at 1 µM). Shown to prevent stress-induced cognitive dysfunction by stabilizing RyR2-calstabin-2 (FKBP12.6) interaction in brain (75 mg/kg/day; p.o.) and maintain exercise capacity by stabilizing RyR1-calstabin-1 (FKBP12) interaction in skeletal muscle (2.5 µg/0.25µL/H/animal; s.c) in mice, as well as restore normal cardiac function (20 mg/kg/day; s.c) in mice with R2474S or S2808D RyR2 mutationin vivo.
