JWH-203 (1-pentyl-3-(2-chlorophenylacetyl)indole) is an analgesic chemical from the phenylacetylindole family, which acts as a cannabinoid agonist with approximately equal affinity at both the CB1 and CB2 receptors, having a Ki of 8.0nM at CB1 and 7.0nM at CB2. Similar to the related 2'-methoxy compound JWH-250, JWH-203 has a phenylacetyl group in place of the naphthoyl ring used in most aminoalkylindole cannabinoid compounds, and is the most potent compound found in the phenylacetyl group.[1][2] It was discovered by, and named after, Dr. John W. Huffman.
