BA6b9
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.

Chemical Properties
| 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 mother liquor preparation method and in vivo formula preparation method:
For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . A total of 10 animals were administered, and the formula you used is 5% 
DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.Preparation method for in vivo formula: Take 50 μL DMSO main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O mix well and clarify
main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O mix well and clarifyFor Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
