JWH-138 (THC-Octyl, Δ8-THC-C8) is a synthetic cannabinoid first synthesised by John W. Huffman, with a Ki of 8.5nM at the CB1 cannabinoid receptor.[1] THC-Octyl and its hydrogenated analog HHC-Octyl was synthesized and studied by Roger Adams as early as 1942.[2]
Isomers
The Δ3/Δ6a(10a) isomer was synthesised in 1941, but was found to be slightly less active than Δ3-THC itself.[3] The alternate isomer Δ9-THC-C8 has also been synthesised,[4] and both the Δ8 and Δ9 isomers are included within the definition of an "intoxicating cannabinoid" in Colorado under the name tetrahydrocannabioctyl,[5] but it is unclear if it has been identified as a natural product. Tetrahydrocannabioctyl is sometimes referred to as THC-Octyl or THCO, which may cause confusion with THC-O-acetate which is commonly known as THC-O.
