JWH-364 ([5-(4-Ethylphenyl)-1-pentyl-1H-pyrrol-3-yl](1-naphthyl)methanone) is a synthetic cannabinoid from the naphthoylpyrrole family which acts as an agonist of the CB1 (Ki = 34 ± 3nM) and CB2 (Ki = 29 ± 1nM) receptors, with a slight selectivity for the latter. JWH-364 was first synthesized in 2006 by John W. Huffman and colleagues to examine the nature of ligand binding to the CB1 receptor.[1]
In the United States JWH-364 is not federally scheduled, although some states have passed legislation banning the sale, possession, and manufacture of JWH-364.[2] [3] [4]
In Canada, JWH-364 and other naphthoylpyrrole-based cannabinoids are Schedule II controlled substances under the Controlled Drugs and Substances Act.
In the United Kingdom, JWH-364 and other naphthoylpyrrole-based cannabinoids are considered Class B drugs under the Misuse of Drugs Act 1971.
