derivatives were potent and efficacious SCRAs, while smaller derivatives generally showed reduced activity at CB1 and CB2, and larger derivatives also showed reduced activity. SAR trends observed were rationalised via in silico induced fit docking. Overall, while natural enantiomers showed equipotent or greater activity than the unnatural isomers in most cases, this was not universal. As such, a number of these
