WS 12 Usage And Synthesis

Description

WS-12 is an agonist of transient receptor potential melastatin 8 (TRPM8). It induces currents in Xenopus oocytes expressing mouse TRPM8 (EC50 = 12 μM) and is selective for TRPM8 over transient receptor potential vanilloid 1-4 (TRPV1-4) and transient receptor potential ankyrin 1 (TRPA1) at 1 mM. WS-12 (6 nmol, i.c.v.) reduces nocifensive behavior induced by capsaicin in wild-type, but not Trpm8-/-, mice. It induces analgesia in the hot plate test, an effect that can be reversed by the opioid receptor antagonist naloxone, in mice.

Chemical Properties

WS 12 is a odorless white crystalline solid,mp 178 °C, displaying a strong initial cooling effect and a long-lastingness. It is used particularly is oral care flavors.

Uses

WS 12 is a potent TRPM8 agonist.

Trade name

Winsense WS-12 (Renessenz)

Biological Activity

Potent TRPM8 agonist that acts as a cooling agent (EC 50 = 193 nM).

Biochem/physiol Actions

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.

storage

Store at -20°C
