NS4591 is a modulator of calcium-activated potassium channels with activity that enhances small (SK) and intermediate (IK) conductivity. NS4591 doubled IK-mediated currents in whole-cell patch-clamp experiments at a concentration of 45 +/- 6 nM, and doubled SK3-mediated currents at a concentration of 530 +/- 100 nM. NS4591 inhibits the number of action potentials generated by suprathreshold depolarizing pulses in acutely isolated bladder primary afferent neurons. NS4591 also reduced carbakol-induced detrusor ring contraction in the rat bladder, demonstrating sensitivity to apamin.
