Biochem/physiol Actions

WS-12 is a high-affinity, selective TRPM8 (cold menthol receptor 1; CMR1) agonist. TRPM8 agonists induce a cooling sensation in sensory neurons and produce profound, mechanistically novel analgesia in chronic pain states such as neuropathic pain.
WS-12 is a menthol derivative, that shows a specific binding affinity towards TRPM8 (transient receptor potential cation channel subfamily M member 8) receptor. TRPM8 is associated with prostate cancer and thus, WS-12 might be useful in reducing the progression of cancer.

Peppermint is traditionally used as an antigalactagogue in breastfeeding women. However, the suppressive mechanism remains unclear. The authors investigate whether and how peppermint influences milk production at the cellular and molecular levels. A lactating mammary epithelial cell (MEC) culture model

Transient receptor potential melastatin member 8 (TRPM8) is a calcium ion (Ca2+)-permeable cation channel that serves as the primary cold and menthol sensor in humans. Activation of TRPM8 by cooling compounds relies on allosteric actions of agonist and membrane lipid

Activation of Gαq-coupled receptors by inflammatory mediators inhibits cold-sensing TRPM8 channels, aggravating pain and inflammation. Both Gαq and the downstream hydrolysis of phosphatidylinositol 4, 5-bisphosphate (PIP2) inhibit TRPM8. Here, I demonstrate that direct Gαq gating is essential for both the

The α1 -adrenoceptor agonist, phenylephrine, is used at high concentrations as a mydriatic agent and for the treatment of nasal congestion. Among its adverse side-effects transient burning sensations are reported indicating activation of the trigeminal nociceptive system. Neuropeptide release, calcium
