Amiodarone hydrochloride (Amiodarone HCl) is an antianginal and class III antiarrhythmic drug. It increases the duration of ventricular and atrial muscle action by inhibiting POTASSIUM CHANNELS and VOLTAGE-GATED SODIUM CHANNELS. There is a resulting decrease in heart rate and in vascular resistance.

Paxilline is an indole alkaloid mycotoxin from *Penicillium paxilli*, acting as a potent BK channel inhibitor via an almost exclusively closed-channel block mechanism. Paxilline possesses significant anticonvulsant activity.

Glibornuride, a blocker of ATP-sensitive K+ channels (pKi: 5.75), inhibits high-affinity [3H]-glibenclamide binding with potencies corresponding to its K+ channel activity.

Glisoxepide is a sulphonamide derivative and is an orally available nonselective K(ATP) channel blocker. It has antihyperglycemic activity and cardiovascular regulation effect.

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).

Y-26763 is a K+ channel opener and active metabolite of Y-27152. This is an ATP-sensitive K+ (KATP) channel activator.

Mitiglinide (KAD-1229) is an insulinotropic agent that is an ATP-sensitive K + (K ATP ) channel antagonist. Mitiglinide is highly specific to the Kir6.2/SUR1 complex (the pancreatic beta-cell K ATP channel). Mitiglinide is able to be used for the research of type 2 diabetes [1] [2].

Cromakalim (BRL 34915) is an ATP-dependent K(+) channel opener and a smooth muscle relaxant.Cromakalim has antiepileptic and anticonvulsant activity and may be useful in studies of asthma and disorders associated with vasodilation.

MCC-134 is an inverse agonist for the pancreatic-type ATP-sensitive K(+) channel. It also used as a vascular relaxing agent.

Iptakalim, a lipophilic para-amino compound, is a novel ATP-sensitive potassium channel (KATP) opener, as well as an α4β2-containing nicotinic acetylcholine receptor (nAChR) antagonist. Iptakalim is also a K(ir) 6.1 SUR2B activator that can attenuate hypoxia-induced pulmonary arterial hypertension in rats by endothelial function protection.

KR-31378, a K(ATP) channel activator, is used potentially for the treatment of ocular hypertension and glaucoma.

Tilisolol is a nonselective blocker of beta-adrenergic. Tilisolol hydrochloride dilates coronary arteries through an ATP-sensitive K(+)-channel opening mechanism in dogs.

ZD-0947, a K(ATP) channel activator, is used potentially for the treatment of overactive bladder (OAB).

5-Hydroxydecanoic acid is a selective ATP-sensitive K+ (KATP) channel blocker (IC50 of ~30 μM). 5-Hydroxydecanoic acid is a substrate for mitochondrial outer membrane acyl-CoA synthetase and has antioxidant activity.

BMS 180448 is a prototype mitochondrial ATP-sensitive K+ (Mitok (ATP)) channel opener with cardioprotective and vasodilating properties.

Guanosine 5'-diphosphate (GDP) is a purine nucleotide and biosynthetic precursor of guanosine 5'-triphosphate .1It has been used to study the conformations of GTPases.2GDP (100 μM) activates sulfonylurea receptor 2B (SUR2B) linked to the inward-rectifier potassium channel 6.1 (Kir6.1) in HEK293T cells in a patch-clamp assay.3 1.Berg, J.M., Tymoczko, J.L., and Stryer, L.Biochemistry(2002) 2.Vetter, I.R., and Wittinghofer, A.The guanine nucleotide-binding switch in three dimensionsScience294(5545)1299-1304(2001) 3.Yamada, M., Isomoto, S., Matsumoto, S., et al.Sulphonylurea receptor 2B and Kir6.1 form a sulphonylurea-sensitive but ATP-insensitive K+ channelJ.

Paederosidic acid methyl ester has antinociception, is possibly related to the pathway of NO-cGMP-ATP sensitive K(+) channels.

Ibutilide Fumarate (U70226E) is the fumarate salt form of ibutilide, a class III antiarrhythmic agent. Ibutilide exerts its effect by activating a slow, inward, predominately sodium current rather than by blocking outward potassium currents. This results in prolongation of atrial and ventricular action potential duration and refractory periods. Ibutilide slightly decreases the sinus rate and atrioventricular (AV) conduction and produces a dose-related prolongation of the QT interval.
