Description | JTV-519 free base (K201 free base), known for its antiarrhythmic and cardioprotective properties, acts as a Ca2+-dependent blocker of sarcoplasmic reticulum Ca2+-stimulated ATPase (SERCA) and as a partial agonist of ryanodine receptors in striated muscle. |
In vitro | JTV-519 shows significant inhibition of Ca2+ movement due to annexin V, and 50% inhibition is achieved at 25 μM K201.JTV-519 inhibits inward Ca2+ movement into large unilamellar vesicles (LUV) caused by annexin V in a dose-dependent manner. In the presence of 50 nM annexin V and 400 μM Ca2+, 3 μM |
In vivo | JTV-519 improves cardiac function in CLP mice, where the fractional shortening (FS) and ejection fraction (EF) are significantly increased as compared with CLP mice without JTV-519 treatment. |
