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).

Application

Icilin has been used as cooling agent in anterior ventromedial preoptic area (VMPO) neurons.

Biochem/physiol Actions

Icilin is a potent agonist at the CMR1 cold- and menthol-sensitive receptor.

3-Iodothyronamine (3T1AM) is an endogenous thyroid hormone metabolite that interacts with the human trace amine-associated receptor 1 (hTAAR1), a G-protein-coupled receptor, to induce numerous physiological responses including dose-dependent body temperature lowering in rodents. 3T1AM also directly activates cold-sensitive transient receptor
