Ion Channel Compound Library

1,286 compounds

Ion channel is a membrane-binding enzyme whose catalytic site is an ion conduction pore, which is opened and closed in response to specific environmental stimuli (voltage, ligand concentration, membrane tension, temperature, etc.). Ion channel provide pores for the passive diffusion of ions on the biofilm. Due to their high selectivity for ion, ion channel are generally classified as sodium (Na⁺ ), potassium (K⁺ ), calcium (Ca²⁺ ), chloride (Cl^- ), and non-specific cation channel. Ion channel is an important contributor to cell signal transduction and homeostasis. In addition to electrical signal transduction, ion channel also have many functions: regulating vascular smooth muscle contraction, maintaining normal cell volume, regulating glandular secretion, protein kinase activation, etc. Therefore, dysfunction of ion channel can lead to many diseases, and its mechanism research is particularly important.

MCE designs a unique collection of 1,286 small molecules related to ion channel, mainly targeting Na⁺ channel, K⁺ channel, Ca²⁺ channel, GABA receptor, iGluR, etc. It is an essential tool for research of cardiovascular diseases, Nervous system diseases and other diseases.

Stromatoxin 1 is an inhibitor of Potassium Channel, a peptide which can be isolated from tarantulas. Stromatoxin 1 selectively inhibits K(V)2.1, K(V)2.2, K(V)4.2, and K(V)2.1/9.3 channels. K(V)2.1 and K(V)2.2, but not K(V)4.2, channel subunits play a key role in opposing both myogenic and neurogenic urinary bladder smooth muscle (UBSM) contractions in rats .

C18 LPA PA(18:0e/0:0)		Phospholipids
C18 LPA (PA(18:0e/0:0)) is a water-soluble phospholipid that functions as a signaling molecule, influencing various cellular responses through G protein-coupled receptors (GPCRs). It is known to promote smooth muscle contraction, cytoskeletal rearrangement, and chemotaxis, while also playing a role in neurotransmitter release, cell proliferation, platelet aggregation, and Ca2+ mobilization. Elevated levels of C18 LPA in human plasma are associated with ovarian cancer and atherosclerosis, suggesting its potential as a biomarker for ovarian cancer.
