Ranolazine dihydrochloride is an antianginal agent with antiarrhythmic properties that acts as a partial fatty acid oxidation inhibitor. Activates pyruvate dehydrogenase in ischemic myocytes to promote glucose oxidation, switching substrate utilization from fatty acids to glucose. Also shown to inhibit late INa and IKr currents.
Ranolazine dihydrochloride is also offered as part of the Tocriscreen 2.0 Max and Tocriscreen FDA-Approved Drugs. Find out more about compound libraries available from Tocris.

Guinea pig ventricular cardiomyocytes were treated (12-16 h) with HOCl-LDL (250 µg/ml). Cells were patched and stimulated at a frequency of 1 Hz. Representative action potentials (shown in Image) recorded in the same cell are shown before (A) and after (B) superfusion with Ranolazine (10 µM, 5 min). For comparative purpose representative APs of a control cardiomyocyte are shown (C).
Application of Ranolazine on acute brain slices to verify for fatty acid oxidation involvement in studied process. It had the same effect as etomoxir (CPT1 blocker), as expected per hypothesis.
