Biological Activity

Description Ranolazine 2HCl (RS-43285) is a calcium uptake inhibitor via the sodium/calcium channal, used to treat chronic angina.
Calcium channel [1]
In vitro

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. [1] 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). [2]

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.

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 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.
