Nicorandil (SG-75)(Ikorel) acts by relaxing the smooth muscle of the blood vessels, especially those of the venous system. It undertakes this through two methods. Firstly, by activating potassium channels, and secondly by donating nitric oxide to activate the enzyme guanylate cyclase. Guanylate cyclase causes activation of cGMP leading to both arterial and venous vasodilatation by de-phosphorylation of the myosin light chain.

GW9508(GW 9508) is a potent and selective agonist for FFA1 (GPR40), stimulates insulin secretion in a glucose-sensitive manner.

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.

Aprikalim (RP 52891) is an adenosine triphosphate potassium channel (KATP) opener that protects against nerve damage in a rabbit model of spinal cord ischemia.Aprikalim inhibits vasoconstriction and inhibits the elevation of [Ca2+]i during myocardial paralysis, and can be used to study cardiovascular disease.

Hydroxyhexamide ((±)-Hydroxyhexamid) is a pharmacologically active metabolite of Acetohexamide, used as a hypoglycemic agent.

U-89232 is an opener of the cardioselective KATP channel.

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.

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.

5-Hydroxydecanoate sodium is a selective ATP-sensitive K+ (KATP) channel blocker with an IC50 of approximately 30 μM and a substrate for mitochondrial outer membrane acyl-CoA synthetase, possessing antioxidant properties.

Levcromakalim (BRL 38227) is an activator of the ATP-sensitive K+ channel.

Amiodarone hydrochloride is an anti-anginal agent and a class III antiarrhythmic drug that inhibits potassium channels (including wild-type hERG channels and their tail currents, with an IC₅₀ of approximately 45 nM) as well as voltage-gated sodium channels. This leads to prolonged action potential duration in ventricular and atrial myocytes, resulting in reduced heart rate and vascular resistance. It activates ERK1/2 and p38 MAPK signaling pathways in fibroblasts, promoting cell proliferation and myofibroblast differentiation. Amiodarone hydrochloride is widely used in the study of supraventricular and ventricular arrhythmias and can also be used to establish pulmonary fibrosis animal models.

Aekatperone, a reversible KATP channel inhibitor, exhibits an IC50 of 9 μM. It is utilized in research related to congenital hyperinsulinism (CHI).

Glipizide (CP 28720) is a short-acting, second-generation sulfonylurea with hypoglycemic activity.

Arachidonic acid (Immunocytophyt) is a polyunsaturated omega-6 essential fatty acid that serves as a major component of biological membranes and animal phospholipids. It is synthesized from dietary linoleic acid and acts as a precursor to lipid mediators such as prostaglandins, thromboxanes, and leukotrienes. Arachidonic acid can improve cognitive responses and cardiovascular function and is commonly used to induce paw edema models.

Chloroprocaine hydrochloride (Chloroprocaine HCl) is a local anesthetic during surgical procedures.

Atpenin A5 is a potent and highly specific complex II inhibitor (IC50 ~10 nM), as well as an effective mKATP channel agonist and cardioprotective agent [1].

OR-1896 is the active metabolite of Levosimendan, a highly specific phosphodiesterase (PDE III) inhibitor, a vasodilator with partial anti-inflammatory properties that produces vasodilation in different types of blood vessels through activation of ATP-sensitive (KATP) and other potassium channels.OR-1896 can be used to study heart failure and vascular dysfunction. OR-1896 can be used to study heart failure and vascular dysfunction.

Minoxidil (U10858) is an orally administered vasodilator with hair growth stimulatory and antihypertensive effects.

Mitiglinide calcium hydrate (S-21403 calcium hydrate) is a drug for the treatment of type 2 diabetes. Mitiglinide is thought to stimulate insulin secretion by closing the ATP-sensitive K(+) K(ATP) channels in pancreatic beta-cells. Mitiglinide belongs to the meglitinide class of blood glucose-lowering drugs and is currently co-marketed in Japan by Kissei and Takeda.

Glibenclamide (Glyburide) is an antidiabetic sulfonylurea derivative with actions similar to those of chlorpropamide.

Polydatin (Piceid), the glycoside of Resveratrol, is originally isolated from the Chinese herb Polygonum cuspidatum. The compound can inhibit platelet aggregation and elevate the ratios of LDL-C/HDL-C and TC/HDL-C. In the myocardial cell, white blood cell, vascular smooth muscle cell, and endothelial cell, Polydatin can inhibit ICAM-1 expression, elevate Ca2+, weaken white blood cell-endothelial cell adhesion, and activate KATP channels.

Naminidil is an opener of cyanoguanidine KATP.

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