UR-144 and XLR11 are potent synthetic cannabinoids (CBs) that have been identified as adulterants of herbal products.[1],[2] Azidoindolene 1 is structurally similar to UR-144, XLR11, and a number of additional synthetic CBs with a hydrazide linking the tetramethylcyclopropyl group to the aminoalkylindole group. The physiological and toxicological properties of this compound are not known. Typically, a tetramethylcyclopropyl group confers selectivity for the peripheral CB2 receptor, and the addition of substituents at the N1-amine of the aminoalkylindole group is necessary for high affinity at either CB1 or CB2.[3] This product is intended for forensic and research applications.
