Our bioassay
Alomone Labs NS8593 blocks KCa2.2 (SK2) currents expressed in HEK 293T cells.A. Time course of KCa2.2 current amplitude and its inhibition by 2 and 10 µM NS8593 (#N-196). Currents were elicited by application of voltage ramp from a holding potential of -100 mV to +60 mV (150 msec), delivered every 10 seconds. B. Superimposed example traces of current responses before and during perfusion of 2 and 10 µM NS8593 as indicated.
Scientific background
NS8593 inhibits the gating modulation of all SK, small conductance Ca2+-activated K+ channels (KCa2.1, KCa2.2, KCa2.3) and blocks SK3 channels with an IC50 of 104 nM1,2. It does so by shifting the apparent Ca2+-dependence to higher Ca2+ concentrations2. NS8593 has no effect on other KCa channels1.
NS8593 was also found to block TRPM7 currents with an IC50 value of 1.6 μM.
Target SK K+ channels, TRPM7
