JWH-251 (1-pentyl-3-(2-methylphenylacetyl)indole) is a synthetic cannabinoid from the phenylacetylindole family, which acts as a cannabinoid agonist with about 5x selectivity for CB1 with a Ki of 29nM and 146nM at CB2. Similar to the related 2'-methoxy compound JWH-250, the 2'-chloro compound JWH-203, and the 2'-bromo compound JWH-249, JWH-251 has a phenylacetyl group in place of the naphthoyl ring used in most aminoalkylindole cannabinoid compounds.
