KR-32568 is a sodium/hydrogen exchanger 1 (NHE-1) inhibitor (IC50: 230 nM) with potent cardioprotective effects. At a concentration of 10 μM, it restored cardiac systolic function in an isolated ischemic rat heart model. Additionally, KR-32568 (0.3 mg/kg) reduced myocardial infarction size in a rat model of ischemia and reperfusion injury.

Product Introduction

Bioactivity

Description	KR-32568 is a sodium/hydrogen exchanger 1 (NHE-1) inhibitor (IC50: 230 nM) with potent cardioprotective effects. At a concentration of 10 μM, it restored cardiac systolic function in an isolated ischemic rat heart model. Additionally, KR-32568 (0.3 mg/kg) reduced myocardial infarction size in a rat model of ischemia and reperfusion injury.
Targets&IC50	NHE1:230 nM
In vitro	KR-32568 (10 nM-1 μM) inhibited NHE-1-mediated platelet swelling induced by intracellular acidification in rabbit platelet-rich plasma in a concentration-dependent manner, with an IC50 value of 24 nM.[1]
In vivo	KR-32568 (0.1-1.0 mg/kg; i.v.; once) exerts effective cardioprotective effects in rats, such as reducing infarct size and significantly reducing the total number of premature ventricular contractions.[1]

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments

and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent

10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO TargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO TargetMol | reagent stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH₂O TargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.

All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
