|Description||Ranolazine 2HCl (RS-43285) is a calcium uptake inhibitor via the sodium/calcium channal, used to treat chronic angina.|
Ranolazine selectively inhibits late I(Na), reduces [Na(+)](i)-dependent calcium overload and attenuates the abnormalities of ventricular repolarisation and contractility that are associated with ischaemia/reperfusion and heart failure in myocardial cells.  Ranolazine significantly and reversibly shortens the action potential duration (APD) of myocytes stimulated at either 0.5 Hz or 0.25 Hz in a concentration-dependent manner in left ventricular myocytes of dogs. Ranolazine at 5 and 10 mM reversibly shortens the duration of twitch contractions (TC) and abolished the after contraction. Ranolazine is found to bind more tightly to the inactivated state than the resting state of the sodium channel underlying I(NaL). 
|In vivo||Ranolazine (10 mM) significantly increases glucose oxidation 1.5-fold to 3-fold under conditions in which the contribution of glucoseto overall ATP production is low (low Ca, high FA, with insulin), high (high Ca, low Fa, with pacing), or intermediate in working hearts. Ranolazine similarly increases glucose oxidation in normoxic Langendorff hearts (high Ca, low FA; 15 mL/min). Ranolazine also significantly increases it during flow reduction to 7 mL/min, 3 mL/min, and 0.5 mL/min. Ranolazine significantly improves functional outcome, which is associated with significant increases in glucoseoxidation, a reversal of the increased FA oxidation seen in control reperfusions (versus preischemic), and a smaller but significant increase in glycolysis in reperfuse dischemic working hearts. |

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
