Galangal pungent component, 1'-acetoxychavicol acetate, activates TRPA1

Biosci Biotechnol Biochem. 2010;74(8):1694-6. doi: 10.1271/bbb.100133. Epub 2010 Aug 7.

Abstract

We investigated the activation of transient receptor potential cation channel (TRP) subfamily V, member 1 (TRPV1) and TRP subfamily A, member 1 (TRPA1) by 1'-acetoxychavicol acetate (ACA), the main pungent component in galangal. ACA did not activate TRPV1-expressing human embryonic kidney (HEK) cells, but strongly activated TRPA1-expressing HEK cells. ACA was more potent than allyl isothiocyanate, the typical TRPA1 agonist.
