List of SGT cannabinoids
Many synthetic cannabinoids were designed by Stargate International, a now defunct New Zealand company in the 2000s and 2010s, and feature an alphanumeric code beginning with the prefix "SGT". PB-22 (SGT-21) is credited with being the first synthetic cannabinoid to feature a quinoline substructure with an ester linker at the indole 3-position.
