Potassium Channel
KcsA
Potassium channels are the most widely distributed type of ion channel and are found in virtually all living organisms. They form potassium-selective pores that span cell membranes. Potassium channels are found in most cell types and control a wide variety of cell functions. Potassium channels function to conduct potassium ions down their electrochemical gradient, doing so both rapidly and selectively. Biologically, these channels act to set or reset the resting potential in many cells. In excitable cells, such asneurons, the delayed counterflow of potassium ions shapes the action potential. By contributing to the regulation of the action potential duration in cardiac muscle, malfunction of potassium channels may cause life-threatening arrhythmias. Potassium channels may also be involved in maintaining vascular tone.

Brompheniramine (Standard)
0 ImagesCat. No.: HY-B0480ARCAS No.: 86-22-6Synonyms: (±)-Brompheniramine (Standard)Brompheniramine (Standard) is the analytical standard of Brompheniramine. This product is intended for research and analytical applications. Brompheniramine ((±)-Brompheniramine) is a potent and orally active antihistamine of the alkylamine class. Brompheniramine is a selective histamine H1 receptor antagonist with a Kd of 6.06 nM. Brompheniramine can block the hERG channels, calcium channels, and sodium channels with IC50s of 0.90 μM, 16.12 μM and 21.26 μM, respectively. Brompheniramine has anticholinergic, antidepressant and anesthetic properties and can be used for allergic rhinitis research[4].

Ebio3
0 ImagesCat. No.: HY-172140Ebio3 is a selective potassium channel (KCNQ2) inhibitor with an IC50 of 1.2 nM. Ebio3 binds to the KCNQ2 channel through its hydrophobic tail, causing the S6 helix to move inward, which leads to the closure of the inner gate. The inhibitory effect of Ebio3 is also effective in pathogenic mutants of KCNQ2 (such as R75C and I238L), where it can inhibit outward currents by more than 80%. Ebio3 is expected to be used in the research of neurological diseases such as epilepsy.

Landiolol
0 ImagesCat. No.: HY-100607CAS No.: 133242-30-5Synonyms: ONO1101Landiolol (ONO1101) is a highly selective, ultra-short-acting competitive inhibitor of β1 adrenergic receptors. Landiolol specifically blocks cardiac β1 receptors, reducing heart rate and myocardial oxygen consumption. Landiolol inhibits TNF-α-induced excessive mitochondrial oxygen consumption and reactive oxygen species production in a sepsis model, alleviating renal injury. Landiolol has little effect on cardiac ion channels (such as L-type calcium current and inward rectifier potassium current) and has a weak negative inotropic effect. Landiolol can be used for perioperative tachycardia control and protection studies of sepsis-related acute kidney injury.
