JWH-019 is an analgesic chemical from the naphthoylindole family that acts as a cannabinoid agonist at both the CB1 and CB2 receptors. It is the N1-hexyl homologue of the more common synthetic cannabinoid compound JWH-018. Unlike the butyl homologue JWH-073, which is several times weaker than JWH-018, the hexyl homologue is only slightly less potent, although extending the chain one carbon longer to the heptyl homologue JWH-020 results in dramatic loss of activity. These results show that the optimum side chain length for CB1 binding in the naphthoylindole series is the five-carbon pentyl chain, shorter than in the classical cannabinoids where a seven-carbon heptyl chain produces the most potent compounds. This difference is thought to reflect a slightly different binding conformation adopted by the naphthoylindole compounds as compared to the classical cannabinoids, and may be useful in characterising the active site of the CB1 and CB2 receptors.[2][3][4]
