Serotonergic psychedelics such as N,N-dimethyltryptamine (DMT) and 4-phosphoryloxy-N,N-dimethyltryptamine (psilocybin) show therapeutic promise for psychiatric and neurodegenerative disorders but may be limited by liabilities from serotonin (5-HT)-2A mediated psychoactive effects and potential cardiotoxicity via 5-HT2B activation. To address these limitations, we designed and synthesized...

With a resurgence in interest in psychedelics as rapid-acting and durable neuroplastic therapies, there is a critical need to develop more selective 5-HT 2A agonists to investigate the basic neurobiological mechanisms of psychedelics. Here, we show that selectivity for 5-HT 2A over the closely related 5-HT 2C receptor can be leveraged using structure-based design to target residue L123 2.53 in...

The serotonin 2C receptor (5-HT 2C ) is a G protein-coupled receptor implicated in multiple physiological and psychological processes and has been investigated as a therapeutic target for neuropsychiatric conditions such as obesity, drug abuse, and depression. With renewed interest in serotonergic psychedelics for treating depression, 5-HT 2C may contribute to psychedelic-induced therapeutic...

5-methoxy-N,N-dimethyltrytpamine (5-MeO-DMT) analogs are used as recreational drugs, but they are also being developed as potential medicines, warranting further investigation into their pharmacology. Here, we investigated the neuropharmacology of 5-MeO-DMT and several of its N-alkyl, N-allyl, and 2-methyl analogs, with three major aims: 1) to determine in vitro receptor profiles for the...
