AB-005 is a synthetic cannabinoid (CB) built on a 1-[(1-methylpiperidin-2-yl)methyl]-indole base that is characteristic of a series of potent CBs, including AM1220 , AM1241 , and AM1248 . The addition of a tetramethylcyclopropyl group has, in some cases, increased selectivity of synthetic CBs for the peripheral CB2 receptor. The physiological and toxicological properties of this compound have not been established. This product is intended for forensic and research applications.
