Deconstruction of lysergic acid diethylamide.

Proceedings of the National Academy of Sciences of the United States of America September 8, 2026 Andrian G Basargin, Andras Domokosa, Joseph J Hennessey et al.

Of the classic psychedelics, lysergic acid diethylamide (LSD) is perhaps the best-known, but its complex chemical architecture has limited synthetic investigations aimed at generating analogues with improved safety and efficacy profiles. Here, we systematically deconstruct the tetracyclic ergoline core of LSD to create 9 simplified ergoline analogues (i.e., ergologs) and evaluate them in...

Indolethylamine N-Methyltransferase Deletion Impacts Mouse Behavior without Disrupting Endogenous Psychedelic Tryptamine Production.

ACS Chemical Neuroscience October 15, 2025 Cassandra J. Hatzipantelis, Lindsay P. Cameron, Min Liu et al.

Exogenously administered psychedelics produce both rapid and long-lasting effects on neuroplasticity and behavior, but it is currently unclear if endogenously produced psychedelics can elicit similar effects. There have been relatively few studies on the role of endogenous psychedelics in health and disease, perhaps owing to the difficulty in quantifying their levels and manipulating their...

Psilocybin during the postpartum period induces long-lasting adverse effects in both mothers and offspring

Nature Communications September 30, 2025 Cassandra J. Hatzipantelis, Min Liu, A. H. G. Love et al. 2 citations

Abstract Psilocybin increases social connectedness and has strong clinical transdiagnostic efficacy for mental illness, making it a candidate treatment to reduce maternal disconnect, anxiety, and blunted affect seen in peripartum mood disorders. However, the efficacy and safety of psilocybin in peripartum mood disorders has not been investigated. We used a social stress model to examine the...

A non-hallucinogenic psychedelic analogue with therapeutic potential.

Nature 2021 Lindsay P. Cameron, Robert J Tombari, Ju Lu et al. 468 citations

The psychedelic alkaloid ibogaine has anti-addictive properties in both humans and animals1. Unlike most medications for the treatment of substance use disorders, anecdotal reports suggest that ibogaine has the potential to treat addiction to various substances, including opiates, alcohol and psychostimulants. The effects of ibogaine-like those of other psychedelic compounds-are long-lasting2,...

Chronic, Intermittent Microdoses of the Psychedelic N , N -Dimethyltryptamine (DMT) Produce Positive Effects on Mood and Anxiety in Rodents

ACS Chemical Neuroscience March 4, 2019 Lindsay P. Cameron, Charlie J. Benson, Brian C. Defelice et al. 163 citations

-dimethyltryptamine (DMT). The behavioral and cellular effects of this dosing regimen were distinct from those induced following a single high dose of the drug. We found that chronic, intermittent, low doses of DMT produced an antidepressant-like phenotype and enhanced fear extinction learning without impacting working memory or social interaction. Additionally, male rats treated with DMT on...

Metabolomic signatures of drug response phenotypes for ketamine and esketamine in subjects with refractory major depressive disorder: new mechanistic insights for rapid acting antidepressants

Translational Psychiatry September 20, 2016 Daniel M. Rotroff, Daniel Corum, Alison A. Motsinger‐Reif et al. 99 citations

Ketamine, at sub-anesthetic doses, is reported to rapidly decrease depression symptoms in patients with treatment-resistant major depressive disorder (MDD). Many patients do not respond to currently available antidepressants, (for example, serotonin reuptake inhibitors), making ketamine and its enantiomer, esketamine, potentially attractive options for treatment-resistant MDD. Although...
