JWH-363 (1-Naphthyl{1-pentyl-5-[3-(trifluoromethyl)phenyl]-1H-pyrrol-3-yl}methanone) is a
synthetic cannabinoid from the naphthoylpyrrole family which acts as an agonist of the
CB1 (Ki = 245 ± 5nM) and
CB2 (Ki = 71 ± 1nM) receptors, with a moderate (~3.45x) selectivity for the latter. JWH-363 was first synthesized in 2006 by
John W. Huffman and colleagues to examine the nature of ligand binding to the
CB1 receptor.[1]
Legality
In the United States JWH-363 is not federally scheduled, although some states have passed legislation banning the sale, possession, and manufacture of JWH-363.[2][3][4][5]
In Canada, JWH-363 and other naphthoylpyrrole-based cannabinoids are Schedule II controlled substances under the
Controlled Drugs and Substances Act.
In the United Kingdom, JWH-363 and other naphthoylpyrrole-based cannabinoids are considered Class B drugs under the
Misuse of Drugs Act 1971.
