Ion Channel Compound Library

1,175 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 1,175 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

157 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 157 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.

Diltiazem-d₆ is the deuterium labeled Diltiazem. Diltiazem is an orally active L-type Ca2+ channel blocker, with antihypertensive and antiarrhythmic effects. Diltiazem can be used for the research of cardiac arrhythmia, hypertension, and angina pectoris[1][2][3].

HY-103309S

ML218-d9

ML218-d₉ is the deuterium labeled ML218. ML218 is a potent, selective and orally active T-type Ca2+ channels (Cav3.1, Cav3.2, Cav3.3) inhibitor with IC50s of 310 nM and 270 nM for Cav3.2 and Cav3.3, respectively. ML218 inhibits the burst activity in subthalamic nucleus (STN) neurons. ML218 has no significant inhibition of L- or N-type calcium channels, KATP or hERG potassium channels. ML218 can penetrate the blood-brain barrier[1].

HY-N0215S14

L-Phenylalanine-15N,d8

L-Phenylalanine- ¹⁵N,d₈ is the deuterium and ¹⁵N-labeled L-Phenylalanine. L-Phenylalanine ((S)-2-Amino-3-phenylpropionic acid) is an essential amino acid isolated from Escherichia coli. L-Phenylalanine is a α2δ subunit of voltage-dependent Ca2+ channels antagonist with a Ki of 980 nM. L-phenylalanine is a competitive antagonist for the glycine- and glutamate-binding sites of N-methyl-D-aspartate receptors (NMDARs) (KB of 573 μM ) and non-NMDARs, respectively. L-Phenylalanine is widely used in the production of food flavors and pharmaceuticals[1][2][3][4].

HY-B1221S

Flufenamic acid-d4

Flufenamic acid-d₄ is deuterium labeled Flufenamic acid. Flufenamic acid is a non-steroidal anti-inflammatory agent, inhibits cyclooxygenase (COX), activates AMPK, and also modulates ion channels, blocking chloride channels and L-type Ca ²⁺ channels, modulating non-selective cation channels (NSC), activating K+ channels. Flufenamic acid binds to the central pocket of TEAD2 YBD and inhibits both TEAD function and TEAD-YAP-dependent processes, such as cell migration and proliferation.

HY-A0057AS2

Gabapentin-d4 hydrochloride
Gabapentin-d4 hydrochloride is the deuterium labeled Gabapentin hydrochloride (HY-A0057A). Gabapentin hydrochloride is a potent, orally active P/Q type Ca ²⁺ channel blocker. Gabapentin hydrochloride inhibits neuronal Ca ²⁺ influx and reduction of neurotransmitter release. Gabapentin hydrochloride is a GABA analog that can be used to relieve neuropathic pain .

HY-B0358AS

Flunarizine-d8 dihydrochloride
Flunarizine-d₈ dihydrochloride is deuterated labeled Flunarizine dihydrochloride (HY-B0358A). Flunarizine dihydrochloride is a potent dual *Na ⁺/Ca ²⁺* channel (T-type) blocker. Flunarizine dihydrochloride is a D₂ dopamine** receptor antagonist. Flunarizine dihydrochloride shows anticonvulsive and antimigraine activity, and peripheral vasodilator effects .
