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.

Drofenine hydrochloride
0 ImagesDrofenine (Cycloadiphene; Hexahydroadiphenine) hydrochloride is an brain-penetrant antispasmodic agent. Drofenine hydrochloride is a Kv2.1 channel inhibitor with human IC50 of 9.53 μM. Drofenine hydrochloride is a butyrylcholinesterase (BChE) inhibitor with Ki of 0.003 mM, and is a TRPV3 activator. Drofenine hydrochloride blocks Kv2.1-dependent potassium efflux, inhibits Kv2.1/JNK/NF-κB and IkBa/NF-kB signaling, suppresses Kv2.1 mRNA/protein expression. Drofenine suppresses oligomeric Aβ-induced microglial NLRP3 inflammasome activation and neuronal Tau hyperphosphorylation, improves cognitive impairment, promotes neurite outgrowth. Drofenine hydrochloride induces calcium influx in keratinocytes and exert cytotoxicity against keratinocytes. Drofenine hydrochloride ameliorates diabetic peripheral neuropathy -like pathology. Drofenine hydrochloride can be used for the researches of Alzheimer's disease, diabetic peripheral neuropathy and smooth muscle spasm.
