Cat.No. 3893 - S 107 hydrochloride | C11H15NOS.HCl | CAS No. 927871-76-9
Description: RyR1 stabilizer; inhibits Ca2+ leak from the SR
Chemical Name: 2,3,4,5-Tetrahydro-7-methoxy-4-methyl-1,4-benzothiazepine hydrochloride
Purity: ≥99% (HPLC)

Biological Activity

Type 1 ryanodine receptor (RyR1) stabilizer; binds RyR1 and enhances the binding affinity of calstabin-1. Inhibits Ca2+ leak from the sarcoplasmic reticulum (SR). Activity results in improved muscle function and increased exercise performance in a Duchenne muscular dystrophy (DMD) mouse model (mdx). Also reduces exercise-induced muscle damage by lowering calpain activation and plasma creatine kinase levels.
