EL20, A Potent Antiarrhythmic Compound, Selectively Inhibits Calmodulin-Deficient Ryanodine Receptor Type 2
This work provides a potential therapeutic mechanism for the development of antiarrhythmic compounds that inhibit leaky RyR2 resulting from CaM dissociation, which is often associated with failing hearts. Our data also suggest that CaM dissociation may contribute to the pathogenesis of arrhythmias with the CPVT-linked R176Q mutation.
