# JWH-249

JWH-249 (1-pentyl-3-(2-bromophenylacetyl)indole) is a synthetic cannabinoid from the phenylacetylindole family, which acts as a cannabinoid agonist with about 2.4 times selectivity for $CB_1$ with a $K_i$ of 8.4 ± 1.8 nM and 20 ± 2 nM at $CB_2.$ Similar to the related 2'-methoxy compound JWH-250, the 2'-chloro compound JWH-203, and the 2'-methyl compound JWH-251, JWH-249 has a phenylacetyl group in place of the naphthoyl ring used in most aminoalkylindole cannabinoid compounds.

In the United States, $CB_1$ receptor agonists of the 3-phenylacetylindole class such as cannabipiperidiethanone are Schedule I Controlled Substances.
