Structure-based discovery of conformationally selective inhibitors of the serotonin transporter.

Cell May 11, 2023 Isha Singh, Anubha Seth, Christian B. Billesbølle et al. 97 citations

The serotonin transporter (SERT) removes synaptic serotonin and is the target of anti-depressant drugs. SERT adopts three conformations: outward-open, occluded, and inward-open. All known inhibitors target the outward-open state except ibogaine, which has unusual anti-depressant and substance-withdrawal effects, and stabilizes the inward-open conformation. Unfortunately, ibogaine's promiscuity...

The G protein biased serotonin 5-HT2A receptor agonist lisuride exerts anti-depressant drug-like activities in mice.

Frontiers in Molecular Biosciences 2023 Vladimir M Pogorelov, Ramona M. Rodriguiz, Bryan L. Roth et al. 26 citations

There is now evidence from multiple Phase II clinical trials that psychedelic drugs can exert long-lasting anxiolytic, anti-depressant, and anti-drug abuse (nicotine and ethanol) effects in patients. Despite these benefits, the hallucinogenic actions of these drugs at the serotonin 2A receptor (5-HT2AR) limit their clinical use in diverse settings. Activation of the 5-HT2AR can stimulate both G...

Bespoke library docking for 5-HT2A receptor agonists with anti-depressant activity

Nature September 28, 2022 Anat Levit Kaplan, Danielle N. Confair, Kuglae Kim et al.

There is considerable interest in screening ultralarge chemical libraries for ligand discovery, both empirically and computationally 1 – 4 . Efforts have focused on readily synthesizable molecules, inevitably leaving many chemotypes unexplored. Here we investigate structure-based docking of a bespoke virtual library of tetrahydropyridines—a scaffold that is poorly sampled by a general...

LSD-stimulated behaviors in mice require β-arrestin 2 but not β-arrestin 1

Scientific Reports September 5, 2021 Ramona M. Rodriguiz, Vineet Nadkarni, Christopher R. Means et al. 92 citations

Abstract Recent evidence suggests that psychedelic drugs can exert beneficial effects on anxiety, depression, and ethanol and nicotine abuse in humans. However, their hallucinogenic side-effects often preclude their clinical use. Lysergic acid diethylamide (LSD) is a prototypical hallucinogen and its psychedelic actions are exerted through the 5-HT2A serotonin receptor (5-HT2AR). 5-HT2AR...

LSD’s effects are differentially modulated in arrestin knockout mice

bioRxiv Preprint Server February 4, 2021 Ramona M. Rodriguiz, Vineet Nadkarni, Christopher R. Means et al. 7 citations preprint

Recent evidence suggests that psychedelic drugs can exert beneficial effects on anxiety, depression, and ethanol and nicotine abuse in humans. However, the hallucinogenic side-effects of psychedelics often preclude their clinical use.
