KRN 4884 is an opener of the K+ channel. KRN 4884 (0.1-3 μM) activates KATP channels in a concentration-dependent manner (EC50=0.55 μM), in the presence of intracellular ATP (1 mM).
Tifenazoxide is an effective and SUR1 Kir6.2 selective KATP channels opener. Tifenazoxide has an anti-diabetic effect, can inhibit glucose-stimulated insulin release in vitro and in vivo.
KCO-912 is a potent and selective opener of ATP-dependent potassium (K ATP) channels. KCO-912 suppresses airways hyperreactivity at doses devoid of cardiovascular effects.
QO-58 is a Kv7 channel opener with EC50 values of 7.0, 1.0, 5.2, 0.6 μM for Kv7.1, Kv7.2, Kv7.3 7.5, Kv7.4 respectively. QO-58 increases the pain threshold of neuropathic pain in a sciatic nerve CCI in vivo.
