JWH-424 is a member of the naphthoylindole family, characterized by its role as a cannabinoid agonist targeting both the CB1 and CB2 receptors. However, it demonstrates moderate selectivity for the CB2 receptor, with a Ki value of 5.44nM at CB2 in contrast to 20.9 nM at CB1. The heavier 8-iodo analog of this compound exhibits even greater selectivity for CB2, especially when compared to its 2-methyl derivative, which boasts a remarkable 40-fold preference for CB2. On the other hand, the 1-propyl homologs in this series display considerably lower affinity at both receptors, indicating a reduced overall association for the 8-substituted naphthoylindoles.
In the United States, JWH-424, like other CB1 receptor agonists belonging to the 3-(1-naphthyl)indole class, is categorized as a Schedule I Controlled Substance.
