Description:

A novel selective, small molecule large-conductance Ca(2+)-activated K(+) channel (BKCa, KCa1.1, MaxiK) positive modulator with EC50 of 11 uM; shows a favorable selectivity profile on Nav, Cav, SK, and IK channels; causes distinct activation from a concentration of 0.3 and 10 µM NS19504 left-shifted the voltage activation curve by 60 mV; reduces spontaneous phasic contractions in guinea pig urinary bladder strips at 1 uM, while having only a modest effect on contractions evoked by electrical field stimulation (EFS) and no effect on high K+-induced contractions.

Cat. No.	Product name	Field of application
DC47375	Guangxitoxin 1E	Guangxitoxin 1E is a potent and selective blocker of KV2.1 and KV2.2 channels. Guangxitoxin 1E inhibits KV2 with an IC50 of 1-3 nM. KV2 channels underlie delayed-rectifier potassium currents in various neurons.
DC47244	Iptakalim hydrochloride	Iptakalim hydrochloride, 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.
DC46591	BeKm-1 TFA	BeKm-1 TFA is a potent and selective KV11.1 (hERG) channel blocker. BeKm-1 TFA is selective for KV11.1 over a panel of 14 other potassium channels. BeKm-1 TFA dose-dependently prolongs QTc interval in isolated rabbit heart.
DC46519	DAD	DAD is a type of ion channel blocker that blocks voltage-gated potassium channels. DAD is a third-generation photoswitch that responds to visible light. DAD has the potential for restoring visual function.
DC46518	DAD dichloride	DAD dichloride is a type of ion channel blocker that blocks voltage-gated potassium channels. DAD dichloride is a third-generation photoswitch that responds to visible light. DAD dichloride has the potential for restoring visual function.
DC46509	Cesium chloride	Cesium chloride is a blocker of potassium channel. Cesium chloride prevents the decrease of Na+ transport produced by Alloxan. Cesium chloride has induced cardiac arrhythmias, including torsade de pointes in animal models.
DC46366	ICA-105665	ICA-105665 (PF-04895162) is a potent and orally active neuronal Kv7.2/7.3 and Kv7.3/7.5 potassium channels opener. ICA-105665 inhibits liver mitochondrial function and bile salt export protein (BSEP) transport (IC50 of 311 μM). ICA-105665 can penetrate the blood-brain barrier and has antiseizure effects.
DC46296	Gliclazide (D4)	Gliclazide D4 (S1702 D4) is the deuterium labeled Gliclazide. Gliclazide (S1702) is a whole-cell beta-cell ATP-sensitive potassium currents blocker with an IC50 of 184 nM. Gliclazide is used as an antidiabetic.
DC45784	UCL 1684 dibromide	UCL 1684 (dibromide) is a first nanomolar, non-peptidic small conductance calcium-activated potassium (SK) channel blocker. UCL 1684 (dibromide) is effective in preventing the development of atrial fibrillation due to potent atrial-selective inhibition of INa. UCL 1684 (dibromide) causes atrial-selective prolongation of ERP secondary to induction of postrepolarization refractoriness.
DC45580	Levosimendan D3	Levosimendan D3 (Simsndan D3) is a deuterium labeled Levosimendan. Levosimendan is a calcium sensitiser used in the management of acutely decompensated congestive heart failure.
