Ranolazine dihydrochloride 98%min Pharmaceutical API Angina pectoris made in china

Ranolazine(RS-43285) is an antianginal agent with antiarrhythmic properties that achieves its effects via a novel mechanism of action (inhibition of the late phase of the inward sodium current), without affecting heart rate or blood pressure (BP). IC50 value:Target: sodium-dependent calcium channelRanolazine is currently approved for use in chronic angina. The basis for this use is likely related to inhibition of late sodium channels with resultant beneficial downstream effects. Randomiz
An acetanilide and piperazine derivative that functions as a SODIUM CHANNEL BLOCKER and prevents the release of enzymes during MYOCARDIAL ISCHEMIA. It is used in the treatment of ANGINA PECTORIS.
Ranolazine is a piperazine derivative with cardioprotective activity. It reduces the late sodium current (INa) 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 Nav1.5 channels (IC50s = 5.9-15 μM) as well as the late potassium current (IKr) 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 (Kis = 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 .
