JWH-249 (1-pentyl-3-(2-bromophenylacetyl)indole) is a synthetic cannabinoid from the phenylacetylindole family, which acts as a cannabinoid agonist with about 2.4x selectivity for CB1 with a Ki of 8.4nM ± 1.8 and 20nM ± 2 at CB2. 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.
