Adekalant (also known as H 345/52) is an innovative antiarrhythmic compound characterized by minimal proarrhythmic activity. It blocks HERG-mediated currents in a concentration-dependent manner, with a half-maximal inhibitory concentration (IC50) of 230 nM. Adekalant binds preferentially to open channels and exhibits rapid kinetic behavior, being trapped when channels close. Its voltage-independent properties have been observed during square pulse and action potential clamp protocols. Research suggests that delaying the repolarization of human cardiac muscle through I(Kr) blockage is the primary mechanism of Adekalant’s action. It effectively blocks I(Kr) while having relatively low efficacy in blocking I(Ca), delaying ventricular repolarization without significantly increasing temporal or spatial dispersion and without inducing early afterdepolarizations or torsades de pointes (TdP).

Calculator
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, and a total of 10 animals are to be administered, using a formulation of 
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 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 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 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.
