Product Description:

Background:

WS 3 is an agonist of TRPM8 receptor with EC50 value of 3.7 μM [1].

Transient receptor potential cation channel subfamily M member 8 (TRPM8) is a Ca2+- and Na+-permeable ion channel and is activated by cooling agents and cold temperatures. TRPM8 belongs to TRP family and is expressed in sensory neurons.

WS 3 is an agonist of TRPM8 receptor and a cooling agent. In HEK293 cells expressed recombinant mouse TRPM8, WS 3 (30 μM) increased [Ca2+]i. WS 3 exhibited potency with EC50 value of 3.7 μM and induced 86% efficacy of the maximal response to icilin, the most potent agonist [1]. In HEK cells stably expressing either hTRPM8 or hTRPA1, WS 3 activated hTRPM8 and hTRPA1 with EC50 values of 2.2 and 120.6 μM, respectively. WS 3 was efficacious in eliciting cooling sensation [2].

4. Others: cigarette, filter tip and other tobacco, it also can be used for driving insects.

Usage:

1. Soluble in Ethanol/PG firstly, then adding water solution.
2. Or dissolved in flavors firstly, then added into your products.
3. Mixed with dementholized peppermint oil can increase the fragrance signally.
