生物&药学活性

BA6b9 is a small molecule, allosteric SK4 channel blocker, reversibly inhibits the SK4 currents with IC50 of 8.6 uM, targets Ca2+-calmodulin (CaM)-PIP2-binding domain.
BA6b9 inhibits SK4 channels by interacting with two specific residues, Arg191 and His192 in the linker S4-S5, not conserved in SK1–SK3 subunits.
cytosol-facing CaM–PIP2-binding domain (CPBD).
BA6b9 (10 uM) potently inhibits the SK4 currents by 66%.
BA6b9 significantly prolonged atrial and atrioventricular effective refractory periods on the electrophysiological properties of the isolated rat hearts.
