Incarvillateine is a complex monoterpene alkaloid that is a derivative of α-truxillic acid. It can be isolated from the plant genus Incarvillea.

Biological activity[edit]

Opioidergic[edit]

Incarvillateine isolated from Incarvillea sinensis has demonstrated significant analgesic activity when compared to the opiate alkaloid morphine.^[1]

Incarvillateine's pain-killing effect was partially blocked by administration of naloxone,^[2] norbinaltorphimine and beta-funaltrexamine,^[3] which are receptor antagonists with varying selectivity for mu and kappa opioid receptors. Naltrindole, a delta opioid receptor antagonist, did not counteract the analgesic activity of incarvillateine.^[3]

These findings indicate that incarvillateine may possess opioidergic receptor activity, but it is worthy to note that some studies indicate that naloxone was ineffective at countering incarvillateine's analgesic activity.^[4]

Adenosinergic[edit]

Incarvillateine's antinociceptive effect was blocked by the administration of adenosine receptor antagonists such as theophylline. This suggests that incarvillateine's main mechanism of action is mediated through the adenosine receptor.^[4]
