“Several works have shown that triterpenes induce peripheral antinociception by activation of cannabinoid receptors and endocannabinoids; besides, several research groups have reported activation of cannabinoid receptors in peripheral antinociception.
The aim of this study was to assess the involvement of the cannabinoid system in the antinociceptive effect induced by tingenone against hyperalgesia evoked by prostaglandin E2 (PGE2) at peripheral level.
The results suggest that tingenone induced a peripheral antinociceptive effect via cannabinoidreceptor activation. Therefore, this study suggests a pharmacological potential for a new analgesic drug.”
