A large number of synthetic cannabinoids (CBs), with differing affinities for the two primary CB receptors, have been generated around a napthoyl indole framework. Many, including certain “JWH” compounds, have been detected in herbal blends sold for recreational use. 1'-Naphthoyl Indole represents the simplest form of this group of cannabimimetics. While the addition of an N-alkyl chain of four or more carbons generates compounds which potently activate CB receptors, short chain lengths are inactive at both CB1 and CB2. This suggests that 1'-naphthoyl indole should have no appreciable affinity for either receptor. This product is intended for forensic and research applications.
