摘要

We searched for novel agonists of TRPA1 in garlic, mioga, galangal, black pepper, and royal jelly by the use of heterogeneously expressed cells. Mioga contained novel and more potent TRPA1 agonists than allyl isothiocyanate (AITC), most famous TRPA1 agonist from wasabi. Garlic and black pepper included both TRPA1 and TRPV1 agonists. A galangal pungent compound had strong activity to TRPA1. Specific fatty acids in royal jelly were TRPA1 active components. In animal studies Intravenous AITC and cinnamaldehyde injection caused adrenaline secretion in rats. Feeding experiments in mice with high-sucrose and high-fat diet resulted in suppression of visceral fat deposition by adding black pepper extract or piperine or cinnamaldehyde. These results suggest that food components activating TRPA1 may enhance energy metabolism or thermogenesis.
