Tetrahydrocannabiphorol (THCP) is a potent phytocannabinoid, a CB1 and CB2 receptor agonist which was known as a synthetic homologue of tetrahydrocannabinol (THC),[1] but for the first time in 2019 was isolated as a natural product in trace amounts from Cannabis sativa.[2][3]
THCP is structurally similar to Δ9-THC, the main active component of cannabis, but with the pentyl side chain extended to heptyl. Since it has a longer side chain, its cannabinoid effects are "far higher than Δ9-THC itself." Tetrahydrocannabiphorol has a reported binding affinity of 1.2 nM at CB1, approximately 33 times that of Δ9-THC (40 nM at CB1).[4]
THCP was studied by Roger Adams as early as 1942.[5]
