| Description | MK-0448 is a novel and selective blocker of the Kv1.5 (KCNA5) channel, a key channel involved in cardiac repolarization that is associated with atrial-specific ultra-rapid K+ current I Kur. |
| In vitro | In vitro studies of MK-0448 demonstrated potent inhibition of I(Kur) with minimal off-target activity. [1] |
| In vivo | In vivo studies of MK-0448 in normal anesthetized dogs demonstrated a significant prolongation of atrial refractory period compared to vehicle controls, without affecting ventricular refractory period. In studies in a heart failure model in conscious dogs, persistent atrial fibrillation was terminated by bolus injections of MK-0448 at doses of 0.03 and 0.1 mg/kg.[1] |

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.
