JWH-424 is a drug from the naphthoylindole family, which acts as a cannabinoid agonist at both the CB1 and CB2 receptors, but with moderate selectivity for CB2, having a Ki of 5.44nM at CB2 vs 20.9nM at CB1. The heavier 8-iodo analogue is even more CB2 selective, with its 2-methyl derivative having 40x selectivity for CB2. However the 1-propyl homologues in this series showed much lower affinity at both receptors, reflecting a generally reduced affinity for the 8-substituted naphthoylindoles overall.
