NS8593 is a selective inhibitor of small conductance Ca2+-activated K+ channels (SK channels), specifically targeting the SK1-3 subtypes. It exhibits a reversible inhibition of SK3-mediated currents with Ca2+-dependent potency (Kd values of 0.42, 0.60, and 0.73 μM, respectively, at 0.5 μM Ca2+), while leaving intermediate and large conductance K channels unaffected. Additionally, NS8593 inhibits the TRPM7 channel with an IC50 of 1.6 mM. This compound is valuable for research into central nervous system-related diseases and the physiological roles of SK and TRPM7 channels.
