Evaluating signaling bias for synthetic cannabinoid receptor agonists at the cannabinoid CB2 receptor

Abstract The rapid structural evolution and emergence of novel synthetic cannabinoid receptor agonists (SCRAs) in the recreational market remains a key public health concern. Despite representing one of the largest classes of new psychoactive substances, pharmacological data on new SCRAs is limited, particularly at the cannabinoid CB2 receptor (CB2). Hence, the current study aimed to characterize the molecular pharmacology of a structurally diverse panel of SCRAs at CB2, including 4‐cyano MPP‐BUT7AICA, 4F‐MDMB‐BUTINACA, AMB‐FUBINACA, JWH‐018, MDMB‐4en‐PINACA, and XLR‐11.
