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.

Dihydroberberine (Standard)
0 ImagesDihydroberberine (Standard) is the analytical standard of Dihydroberberine. This product is intended for research and analytical applications. Dihydroberberine is a naturally occurring isoquinoline alkaloid with anti-inflammatory, anti-atherosclerotic, hypolipidemic and anti-tumor activities. Dihydroberberine inhibits the human ether-related gene (hERG) channel and significantly reduces the expression of heat shock protein 90 (Hsp90) and its interaction with hERG. Dihydroberberine also blocks the TLR4/MyD88/NF-κB signaling pathway to reduce pro-inflammatory cytokines and immunoglobulins, and has inhibitory effects on DSS (HY-116282C)-induced experimental colitis. Dihydroberberine also increases the sensitivity of lung cancer to sunitinib (HY-10255A), with synergistic efficacy.
