BA6b9
😃Good
Catalog No. T88799Cas No. 609335-29-7
BA6b9 is an allosteric inhibitor targeting the SK4 channel via the CaM-PIP2 binding domain. It interacts with two critical residues, Arg191 and His192, located in the S4-S5 linker to inhibit the SK4 channel, with an IC50 of 8.6 μM (WT SK4). BA6b9 significantly prolongs the effective refractory period (ERP) of the atria and atrioventricular node in isolated rat hearts, reducing the induction of atrial fibrillation (AF), highlighting its potential for arrhythmia research.

| Description | BA6b9 is an allosteric inhibitor targeting the SK4 channel via the CaM-PIP2 binding domain. It interacts with two critical residues, Arg191 and His192, located in the S4-S5 linker to inhibit the SK4 channel, with an IC50 of 8.6 μM (WT SK4). BA6b9 significantly prolongs the effective refractory period (ERP) of the atria and atrioventricular node in isolated rat hearts, reducing the induction of atrial fibrillation (AF), highlighting its potential for arrhythmia research. |
| In vitro | BA6b9 (10 μM) significantly inhibits Ca2+-activated SK4 channels by increasing the EC50 for Ca2+ activation from 65 nM to 435 nM. In the isolated heart model of adult male Sprague-Dawley rats (200-250 g) using Langendorff perfusion, BA6b9 induces a reduction in heart rate, prolongation of the PR interval, and extension of the effective refractory periods (ERP) in the atria and atrioventricular node, while also suppressing carbachol-induced atrial fibrillation (AF). |

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.
