| Hazard Information | Back Directory | [Description]
Icilin (36945-98-9) is an activator of cold-sensitive TRP channels with 2.5-fold greater efficacy and 200-fold greater potency than menthol (EC50?= 0.36 μM for CRM1, rat orthologue of TRPM8).1 Activator at TRPM8 (EC50?= 0.2 μM)2?and ANKTM1(TRPA1)3. Activator effects require Ca2+?and are pH dependent.2,4?Icilin induced G1?arrest in PC-3 prostate cancer cells without cell death.5 | [Uses]
Icilin has been used as cooling agent in anterior ventromedial preoptic area (VMPO) neurons. | [Definition]
ChEBI: 3-(2-hydroxyphenyl)-6-(3-nitrophenyl)-1,4-dihydropyrimidin-2-one is a C-nitro compound. | [General Description]
Icilin is a synthetic cooling agent and modulates human transient receptor potential cation channel (TRPA1). Icilin inhibits transient receptor potential cation channel subfamily M member 8 (TRPM8) and modulates calcium release. Icilin also suppresses transient receptor potential vanilloid subtype 3 (TRPV3). | [Biological Activity]
Cooling agent that activates the novel cold receptors TRPM8 (CMR1) and TRPA1 (ANKTM1/TRPN1), members of the TRP ion channel family. Induces currents in CMR1-expressing HEK-293 cells (EC 50 = 0.36 μ M) more potently than menthol or low temperatures. Produces "wet shakes" in vivo . | [Biochem/physiol Actions]
Icilin is a potent agonist at the CMR1 cold- and menthol-sensitive receptor. | [storage]
