Ion Channel Compound Library

1,656 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 1,656 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.

Calcium Channel Blocker Library

215 compounds

Calcium channel blockers (CCBs), also called calcium antagonists are compounds that slow the movement of calcium (Ca2+) through calcium channels into the cells of the heart and blood vessel walls. Calcium causes the heart and arteries to squeeze more strongly. By blocking calcium, calcium channel blockers allow blood vessels to relax and open. So calcium channel blockers are usually used to lower blood pressure, relieve chest pain (angina) and control an irregular heartbeat.

MCE supplies a unique collection of 215 calcium channel blockers and antagonists, all of which have the identified inhibitory effect on calcium channel. MCE Calcium Channel Blocker Library is a useful tool for discovery of antihypertensive drugs and cardiovascular disease research.

Ion Channel Lead-like Compound Library

9000 compounds

Ion channels are key proteins on the cell membrane that regulate the flow of ions across membranes. They participate in nearly all physiological processes, including nerve conduction, muscle contraction, heart rhythm, and pain perception. Abnormalities in their function can lead to various serious diseases such as arrhythmia, epilepsy, hypertension, neuropathic pain, and cancer. Therefore, ion channels are highly valuable drug targets—over 15% of approved drugs target ion channels currently, demonstrating their irreplaceable therapeutic value in cardiovascular, neurological, and analgesic fields.

MCE has collected a library of over 5,000 reported ion channel-related bioactive compounds targeting major sites such as Na+ channels, K+ channels, Ca2+ channels, GABA receptors, iGluRs, and others. Using AI models, these compounds are characterized through both 2D representations (molecular fingerprints, pharmacophores) and 3D representations (3D conformation) to screen for a collection of lead-like compounds highly similar to known active molecules. Additionally, an hERG channel prediction algorithm integrating XGB and ISE mapping strategy is employed to assess and exclude potential cardiotoxicity in the library.. This step significantly reduces safety risks in subsequent screenings, particularly for ion channel drug development related to cardiovascular systems (e.g., Nav1.5, Cav1.2), effectively minimizing failures due to hERG inhibition and serving as a valuable tool for ion channel drug screening.

Mavatrep (JNJ-39439335) is an orally active, selective and potent TRPV1 antagonist with high affinity for hTRPV1 channels (K_i=6.5 nM). Mavatrep antagonizes capsaicin-induced Ca ²⁺ influx with an IC₅₀ value of 4.6 nM. Mavatrep can be used in some studies of neuropathic pain .

HY-B0380S2

Trimebutine-d3 hydrochloride

Trimebutine-d₃ hydrochloride is deuterium labeled Trimebutine hydrochloride. Trimebutine hydrochloride is a multi-target inhibitor and opioid receptor agonist with antimuscarinic activity. Trimebutine hydrochloride inhibits L-type Ca ²⁺ channels and large-conductance calcium-activated potassium channels (BK_Ca channels), thereby inhibiting extracellular calcium influx and potassium ion efflux. Trimebutine hydrochloride also targets Toll-like receptors, inhibits Toll-like receptor 2/4/7/8/9 signals, and inhibits LPS-induced IRAK1 activation, as well as ERK1/2, JNK and NF-κB activation, thereby exerting anti-inflammatory effects. Trimebutine hydrochloride also induces tumor cell apoptosis by inhibiting the AKT/ERK pathway. Trimebutine hydrochloride also inhibits excessive contraction of smooth muscle and can be used in the study of gastrointestinal disorders such as irritable bowel syndrome (IBS) .

HY-B0549S

Flavoxate-d5

Flavoxate-d₅ is deuterium labeled Flavoxate. Flavoxate hydrochloride (Rec-7-0040; DW61) is an orally active L-type Ca ²⁺ channel inhibitor and antispasmodic. Flavoxate hydrochloride inhibits cyclic adenosine monophosphate production by blocking voltage-dependent inward Ba ²⁺ currents, regulating the brainstem micturition center, and stimulating G protein-coupled receptors. Consequently, Flavoxate hydrochloride induces relaxation of bladder smooth muscle and inhibits isovolumetric rhythmic contractions. Flavoxate hydrochloride effectively increases bladder capacity and alleviates symptoms of urgent urination frequency and pollakiuria caused by overactive bladder. Flavoxate hydrochloride can be used in research on overactive bladder and related voiding dysfunctions .

HY-B0549AS

Flavoxate-d4 hydrochloride

Flavoxate-d₄ hydrochloride (Rec-7-0040-d₄) is the deuterium labeled Flavoxate hydrochloride. Flavoxate hydrochloride (Rec-7-0040; DW61) is an orally active L-type Ca ²⁺ channel inhibitor and antispasmodic. Flavoxate hydrochloride inhibits cyclic adenosine monophosphate production by blocking voltage-dependent inward Ba ²⁺ currents, regulating the brainstem micturition center, and stimulating G protein-coupled receptors. Consequently, Flavoxate hydrochloride induces relaxation of bladder smooth muscle and inhibits isovolumetric rhythmic contractions. Flavoxate hydrochloride effectively increases bladder capacity and alleviates symptoms of urgent urination frequency and pollakiuria caused by overactive bladder. Flavoxate hydrochloride can be used in research on overactive bladder and related voiding dysfunctions .

HY-135746S

OR-1896-d3
OR-1896-d₃ is the deuterium labeled OR-1896 (HY-135746). OR-1896 is an active long-lived metabolite of Levosimendan. OR-1896 is a highly selective phosphodiesterase (PDE) III isoform inhibitor and a powerful vasodilator. OR-1896 can open ATP-sensitive K+ channels and has Ca2+-sensitizing effect. OR-1896 mitigates cardiomyocyte apoptosis, cardiac remodeling and myocardial inflammation .
