However, the precise mechanisms by which these drugs bring about benefits and the potential clinical risks are not yet fully understood. The serotonin 2A receptor (5-HTR) was reported to be a G-coupled receptor and the primary interoceptive target of psychedelics. Here we compared psychedelics and their non-hallucinogenic analogues (nHAs) using in vitro and in vivo approaches, finding that 5-HTR-mediated non-canonical G signalling is essential for hallucinogenic effect. We further presented five cryo-electron microscopy structures of 5-HTR-G/G in complex with psychedelics or nHAs. Structural analysis and pharmacological investigation revealed that a special contact between nHAs with 5-HTR mediated the signalling bias. Building on this insight, we identified a 2,5-dimethoxy-4-iodoamphetamine derivative, DOI-NBOMe, which exhibits potent and selective G-biased activity, and demonstrates promising therapeutic effects in mouse models without hallucinogenic effect. Our finding uncovers the functional mechanisms underlying the G signalling mediated by 5-HTR and provides valuable insights for designing psychedelic-based drugs with minimized risk from hallucinogenic effects. | |||||||||
