Pain-Related Compound Library	2,425 compounds
Pain is a kind of distressing feeling caused by the stimulation of tissue damage. According to the International Association for the Study of Pain (IASP), pain is defined as ”An unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage”. Pain is usually classified according to its location, duration, underlying causes, and intensity. For example, acute and chronic pain, muscle pain, and nerve pain. Pain is the main symptom of most diseases, which seriously affects the quality of life and body function of patients. In the medical treatment of pain, anti-inflammatory drugs and opioid analgesic agents have traditionally been used, but the side effects are serious. In recent years, targeted drugs targeting the ERK/MAPK pathway or other targets have gradually become a research hotspot. MCE supplies a unique collection of 2,425 compounds targeting key proteins in the pain system. MCE Pain-Related Compound Library is a useful tool for pain related research and anti-pain drug development.

Sodium Channel Blocker Library	154 compounds
Sodium channels conduct sodium ions (Na+) through a cell's plasma membrane that are the source of excitatory currents for the nervous system and muscle. Na channels are classified according to the trigger that opens the channel for such ions, i.e. either a voltage-change (Voltage-gated, voltage-sensitive, or voltage-dependent sodium channel also called VGSCs or Nav channel) or a binding of a substance (a ligand) to the channel (ligand-gated sodium channels). Dysfunction in voltage-gated sodium channels correlates with neurological and cardiac diseases, including epilepsy, myopathies, pain and cardiac arrhythmias. Sodium channel blockers are used in the treatment of cardiac arrhythmia, pain and convulsion. MCE offers a unique collection of 154 sodium channel blocker and antagonists, all of which have the identified inhibitory effect on sodium channels.

Camphor is an agonist of monoterpenoid transient receptor potential (TRP) channels (such as TRPV1, TRPV3, TRPM8) and an inhibitor of TRPA1 channels. Camphor's derivatives have multiple biological activities, including antibacterial, antiviral, antioxidant, analgesic and anticancer. Camphor can selectively activate cold-sensitive TRP channels and inhibit TRPA1-mediated nociceptive signals. Camphor stimulates the cold-sensing nerve endings in the skin and regulates the activity of ion channels to exert analgesic, anti-inflammatory and anti-itching effects. It also has anti-proliferative and anti-mutagenic activities on tumor cells, which may be related to inhibiting ribosome function or inducing cell apoptosis. Camphor can be absorbed through the skin and (+)-Camphor can be used in the study of muscle and joint pain and inflammation .

Eperisone-d10 hydrochloride

Eperisone-d₁₀ (hydrochloride) is the deuterium labeled Eperisone hydrochloride. Eperisone Hydrochloride ((±)-Eperisone hydrochloride) is an antispastic agent used for treatment of diseases characterized by muscle stiffness and pain. It works by relaxing both skeletal muscles and vascularsmooth muscles, thus demonstrating avariety of effects such as reduction ofmyotonia, improvement of circulationand suppression of the pain reflex. Eperisone Hydrochloride ((±)-Eperisone hydrochloride) is a centrally acting muscle relaxant inhibiting the pain reflex pathway, having a vasodilator effect[1][2 [3].

HY-B1695S

Methyl nicotinate-d4
Methyl nicotinate-d₄ is the deuterium labeled Methyl nicotinate[1]. Methyl nicotinate, the methyl ester of Niacin found in alcoholic beverages, that is used as an active ingredient as a rubefacient in over-the-counter topical preparations indicated for muscle and joint pain[2].

HY-B0262S1

Methocarbamol-d3
Methocarbamol-d₃ is the deuterium labeled Methocarbamol. Methocarbamol is an orally active central muscle relaxant and blocks muscular Nav1.4 channel. Methocarbamol reversibly affects voltage dependence of inactivation of Nav1.4 channel. Methocarbamol has the potential for muscle spasms and pain syndromes research[1][2][3].

HY-B1462S

Chlorzoxazone-d3
Chlorzoxazone-d₃ is the deuterium labeled Chlorzoxazone. Chlorzoxazone is a centrally acting muscle relaxant used to treat muscle spasm and the resulting pain or discomfort. It acts on the spinal cord by depressing reflexes.Chlorzoxazone is currently being used as a marker substrate in vitro/vivo studies to quantify cytochrome P450 2E1 (CYP2E1) activity in humans.

HY-B1462S1

Chlorzoxazone-13C
Chlorzoxazone- ¹³C is the ¹³C labeled Chlorzoxazone[1]. Chlorzoxazone is a centrally acting muscle relaxant used to treat muscle spasm and the resulting pain or discomfort[2].

HY-B0262S2

Methocarbamol-13C,d3
Methocarbamol- ¹³C,d₃ is the ¹³C- and deuterium labeled Methocarbamol. Methocarbamol is an orally active central muscle relaxant and blocks muscular Nav1.4 channel. Methocarbamol reversibly affects voltage dependence of inactivation of Nav1.4 channel. Methocarbamol has the potential for muscle spasms and pain syndromes research[1][2][3].

HY-B0740S3

Cyclobenzaprine-d3-1 hydrochloride

Cyclobenzaprine-d3-1 hydrochloride (MK130-d3-1 hydrochloride) is the deuterium labeled Cyclobenzaprine hydrochloride (HY-B0740). Cyclobenzaprine (MK130) hydrochloride is an orally active 5-HT₂ receptor antagonist. Cyclobenzaprine hydrochloride acts centrally, providing skeletal muscle relaxation, alleviating muscle spasms, and reducing pain. Additionally, Cyclobenzaprine hydrochloride has antiprotozoal activity. Additionally, Cyclobenzaprine hydrochloride also possesses antiparasitic activity. Cyclobenzaprine hydrochloride holds promise for research in the fields of acute, painful skeletal muscle disorders and infectious diseases

HY-B1833S

Afloqualone-d7
Afloqualone-d₇ (HQ-495-d₇) is deuterium labeled Afloqualone. Afloqualone (HQ-495) is an orally active central muscle relaxant and antivertiginous agent that can increase the sensitivity of GABA receptors in neurons of the lateral vestibular nucleus. Afloqualone (HQ-495) can be used in the research of low back pain and neck-arm-shoulder syndrome .

HY-B1126S

Orphenadrine-d3 hydrochloride

Orphenadrine-d₃ (hydrochloride) is the deuterium labeled Orphenadrine hydrochloride[1]. Orphenadrine hydrochloride is an orally active and non-competitive NMDA receptor antagonist (crosses the blood-brain barrier) with a Ki of 6.0 μM. Orphenadrine hydrochloride relieves stiffness, pain and discomfort due to muscle strains, sprains or other injuries. Orphenadrine hydrochloride is also used to relieve tremors associated with parkinson's disease. Orphenadrine citrate has good neuroprotective properties, can be used in studies of neurodegenerative diseases[2][3].
