Additionally, the indole core is substituted at R3 with a carbonyl team which happens to be also bonded into a napthalene moeity. Napthalene is usually a bicyclic framework of two fused benzene rings. This carbonyl bridge of JWH-018 classifies it like a ketone. JWH-018 is surely an analog of THJ-018, by which the Main indazole structure is substitu
