Cat.No.  Name Information
M7029 Nigericin sodium salt Nigericin (NSC 292567) sodium salt is a selective K+ ionophore, Nigericin sodium salt is also an NLRP3 activator which can activate NLRP3 inflammasome to induce pro-inflammatory and immunostimulatory processes.
M4973 BAPTA-AM BAPTA-AM is a selective, membrane-permeable calcium chelator. BAPTA-AM inhibits hERG channels, hKv1.3 and hKv1.5 channels in HEK 293 cells with IC50s of 1.3 μM, 1.45 μM and 1.23 μM, respectively.
M3456 Chlorpromazine hydrochloride Chlorpromazine hydrochloride is an antagonist of D2, 5HT2A, potassium and sodium channels. The Ki of Chlorpromazine Hydrochloride to D2 and 5HT2A were 363 nM and 8.3 nM, respectively. Chlorpromazine also excites the 20S proteasome. *The compound is unstable in solutions, freshly prepared is recommended
M2181 ML133 hydrochloride ML133 hydrochloride is a selective inhibitor of the Kir2 family of inward rectifier (IRK, KCNJ) potassium channels.
M58185 VU0810464 VU0810464 is a potent and selective non-ureaG protein-gated inwardly-rectifying potassium channels (GIRK, Kir3) activator. VU0810464 displays nanomolar potency for neuronal (EC50=165 nM) and GIRK1/4 (EC50=720 nM) channels with improved brain penetration.
M55441 Retigabine-d4 Retigabine-d4
M53944 Apamin Apamin (Apamine) is a specifically selective blocker of Ca2+-activated K+ (SK) channels and exhibits anti-inflammatory and anti-fibrotic activity.
M52749 Spadin Spadin, a natural peptide derived from a propeptide released in blood, is a potent TREK-1 channel blocker with IC50 value of 10 nM.
M52734 Phrixotoxin-1 Phrixotoxin 1, from the venom of the theraphosid spider Phrixotrichus auratus, is a specific peptide inhibitor of Kv4 potassium channel.
M31356 Iberiotoxin TFA Iberiotoxin TFA is also a selective, high-affinity blocker of the large conductance calcium-activated potassium channel (BKCa) with a Kd of approximately 1 nM.
M30635 Quinine hemisulfate Quinine hemisulfate is an orally active alkaloid extracted from cinchona bark and can be used in anti-malarial studies. Quinine hemisulfate is a potassium channel inhibitor that inhibits WT mouse Slo3 (KCa5.1) channel currents evoked by voltage pulses to +100 mV with an IC50 of 169 μM.
M30266 Flecainide  Flecainide is a potent and orally active antiarrhythmic agent. Flecainide blocks the cardiac fast inward Na+ current (INa) and the rapid component of the delayed rectifier K+ current. Flecainide prolongs the action potential duration (APD) in ventricular and atrial muscle fibres. Flecainide has the potential for the research of fetal tachycardias.
M29046 Amiodarone Amiodarone is an antiarrhythmic agent for inhibition of ATP-sensitive potassium channel with an IC50 of 19.1 μM.
M27722 Linopirdine Linopirdine (DuP 996) is an orally active, selective M-type K+ current (IM; Kv7; KCNQ Channels) inhibitor with an IC50 of 2.4 μM. Linopirdine is a TRPV1 agonist. Linopirdine, a putative cognition enhancing agent, increases acetylcholine release in rat brain tissue.
M22444 Flupirtine Flupirtine
M21491 Rimtuzalcap Rimtuzalcap (CAD-1883) is the first (first-in-class), selective small conductance calcium-activated potassium channel (SK channel) positive allosteric regulator. Rimtuzalcap can be used in the study of movement disorders including essential tremor (ET) and spinocerebellar ataxia (SCA).
M20808 ML277 ML277 (CID-53347902) is a potent activator of KCNQ1 channels with an EC50 of 260 nM and shows >100-fold selectivity over KCNQ2 and KCNQ4.
M20428 Retigabine 2HCl Retigabine is a novel anticonvulsant with activity in a broad range of seizure models. The mechanism of action involves opening of neuronal K(V)7.2-7.5 (formerly KCNQ2-5) voltage-activated K(+) channels.
M14263 Tertiapin-Q Tertiapin-Q is a highly selective blocker of GIRK1/4 heterodimer and ROMK1 (Kir1.1).
M14262 Tannic acid Tannic acid is a novel hERG channel blocker with IC50 of 3.4 μM.
