Product nameCibenzoline, K channel blocker
DescriptionATP-sensitive K channel blocker
Class IA antiarrhythmic drug. Blocks ATP-sensitive K channels in heart and pancreatic beta cells. Interacts with the channel pore-forming subunit of the K(ATP) channel (Kir6.2) from the cytoplasmic side. Inhibits the delayed rectifier K current [I(Kr)] in sino-atrial node cells.
Storage instructionsStore at -20°C. Store In the Dark. Store under desiccating conditions. This product is air and light sensitive and impurities can occur as a result of air oxidation or due to metabolism by microbes.
Solubility overviewSoluble in water to 10 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
