Perrottetinene is a naturally occurring cannabinoid compound found in liverworts from the genus Radula native to Japan, New Zealand and Costa Rica, namely Radula perrottetii, Radula marginata and Radula laxiramea,[1] [2] along with a number of similar compounds.[3] [4] Its chemical structure closely resembles that of THC, the main active component of marijuana but with a cis rather than trans conformation and a bibenzyl tailchain instead of pentyl.[5] The absolute configuration of perrottetinene was established in 2008 by an enantioselective total synthesis.[6]

Pharmacology

In 2018, a study showed that perrottetinene is mild to moderately psychoactive through activation of the cannabinoid receptor 1. (-)-cis-PET was found to have a binding affinity of 481nM at CB1 and 225nM at CB2 while the unnatural (-)-trans-PET was found to have a binding affinity of 127nM at CB1 and 126nM at CB2, both acting as partial agonists. In terms of binding affinity this study found cis-PET to be over 22x weaker than Delta-9-THC. The same study also reported significantly reduced prostaglandin D2 and E2 brain concentrations in mice after perrottetinene administration.[7]

Perrottetinene is structurally related to machaeriol A and other machaeriols found in Machaerium species.[8]
