Potassium Channels

Eleclazine, also known as GS-6615, is a selective late sodium current inhibitor. Eleclazine is potentially useful for treatment of coronary vasodilators, antiarrhythmics and vasodilators.

VU590 is a potent and moderately selective ROMK (Kir1.1) inhibitor, with an IC50 of 290 nM. VU590 also inhibits Kir7.1, with an IC50 of 8 μM. VU590 is not a good probe of ROMK function in the kidney.

NS19504 is a Ca2+-activated K+ channel (BK channel, KCa1.1 channel) activator (EC50=11.0 μM) with relaxing effect on bladder smooth muscle spontaneous phasic contractions.

Gliclazide is used as an antidiabetic. It is a whole-cell beta-cell ATP-sensitive potassium currents blocker with an IC50 of 184 nM.
