H3B-120 is a highly selective, competitive and allosteric carbamoyl phosphate synthetase 1 (CPS1) inhibitor with an IC50 of 1.5 μM and a Ki of 1.4 μM. H3B-120 has anti-cancer activity[1].
Nicorandil-d4 (SG-75-d4) is the deuterium labeled Nicorandil. Nicorandil (SG-75) is a potent potassium channel activator and targets vascular nucleoside diphosphate-dependent K+ channels and cardiac ATP-sensitive K+ channels (KATP). Nicorandil is a nicotinamide ester with vasodilatory and cardioprotective effects and has the potential for angina and forischemic heart diseases[1][2][3].
Isoallolithocholic acid-d2 is the deuterium labeled Isoallolithocholic acid. Alloisolithocholic acid (AILCA) activates large-conductance calcium-activated potassium (BK) channels with an EC50 value of 44.21 μM in Xenopus oocytes[1][2].
Loureirin B, a flavonoid extracted from Dracaena cochinchinensis, is an inhibitor of plasminogen activator inhibitor-1 (PAI-1), with an IC50 of 26.10 μM; Loureirin B also inhibits KATP, the phosphorylation of ERK and JNK, and has anti-diabetic activity.
KVI-020 is an orally active, potent and selective blocker of the atrial potassium channel Kv1.5, with an IC50 of 480 nM. KVI-020 can inhibits hERG, with an IC50 of 15100 nM. KVI-020 is a potent antiarrhythmic agent, and can be used for atrial fibrillation (AF) research[1].
PBFI-AM is a useful tool to determine intracellular K+ content[1].
Cesium chloride is a blocker of potassium channel. Cesium chloride prevents the decrease of Na+ transport produced by Alloxan[1][2]. Cesium chloride has induced cardiac arrhythmias, including torsade de pointes in animal models[3].
ICA 110381 (Compound 16) is a KCNQ2/Q3 potassium channel opener for the treatment of epilepsy. ICA 110381 is a KCNQ2/Q3 agonist (EC50=0.38 μM) as well as KCNQ1 antagonist (IC50=15 μM)[1].
