JTV-519 (K201) is a 14-benzothiazepine derivative that interacts with many cellular targets. It has many structural similarities to diltiazem a Ca2+ channel blocker used for treatment of hypertension angina pectoris and some types of arrhythmias. JTV-519 acts in the sarcoplasmic reticulum (SR) of cardiac myocytes by binding to and stabilizing the ryanodine receptor (RyR2) in its closed state.
