Ranolazine dihydrochloride Usage And Synthesis

Description

Ranolazine is a piperazine derivative with cardioprotective activity. It reduces the late sodium current (I_Na) in mouse myocytes expressing the long QT syndrome 3 mutant sodium channel DKPQ, ventricular myocytes isolated from a canine model of heart failure, guinea pig ventricular myocytes exposed to hydrogen peroxide or anemone toxin-II, and HEK293 cells expressing human Na_v1.5 channels (IC₅₀s = 5.9-15 μM) as well as the late potassium current (I_Kr) in canine ventricular myocytes and HEK293 cells (IC₅₀s = 11.5 and 14.4 μM, respectively). Ranolazine also inhibits radioligand binding to α₁-, β₁-, and β₂-adrenergic receptors (K_is = 8.2-19.5, 1.4-8.6, and 0.5-14.8 μM, respectively). In vivo, ranolazine (480 μg/kg per min) reduces clofilium-induced prolongation of the QTc interval and Torsade de Pointes (TdP) in rabbits. Ranolazine also reduces interstitial collagen deposition as well as atrial natriuretic peptide (ANP; Item Nos. 24539 | 24276), connective tissue growth factor (CTGF), brain natriuretic peptide (BNP; ), and matrix metalloproteinase-2 (MMP-2) mRNA levels, and prevents left ventricular dilation in a mouse model of cardiotoxicity induced by doxorubicin .

Chemical Properties

White Crystalline Powder

Uses

Ranolazine Dihydrochloride is an anti-ischemic agent which modulates myocardial metabolism. Antianginal.

Uses

treatment of angina and congestive heart failure

Biological Activity

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 I Na and I Kr currents.

Biochem/physiol Actions

Ranolazine is a derivative of anti-ischemic piperazine and acts as sodium (Na+)-current inhibitor. It has the potential to treat diastolic heart failure and helps in ameliorating myocardial diastolic function.
