BA6b9

BA6b9 is an allosteric inhibitor of SK4 channels that targets the CaM–PIP2-binding domain with a IC₅₀ value of 8.6 µM (WT SK4). BA6b9 inhibits SK4 channels by interacting with two specific residues, Arg191 and His192 in the S4–S5 linker. BA6b9 significantly prolongs atrial and atrioventricular effective refractory period (ERP) and reduces atrial fibrillation (AF) induction in rat isolated hearts, which has the potential to be used for the research of arrhythmia .

Description

IC₅₀ & Target

IC₅₀: 8.6 μM (WT SK4 Channel)^[1]

In Vitro

BA6b9 (10 μM) strongly inhibits calcium-activated SK4 channels by raising the EC₅₀ for Ca²⁺ activation from 65 nM to 435 nM ^[1].
BA6b9 (10 μM) exhibits a reduced heart rate, an increased PR interval, prolongation of atrial and atrioventricular effective refractory period (ERP) , and inhibits carbachol-induced atrial fibrillation (AF) in the Langendorff isolated heart model from adult male Sprague-Dawley rats (200-250 g) ^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
