The novel methoxetamine analogs N-ethylnorketamine hydrochloride (NENK), 2-MeO-N-ethylketamine hydrochloride (2-MeO-NEK), and 4-MeO-N-ethylketamine hydrochloride (4-MeO-NEK) elicit rapid antidepressant effects via activation of AMPA and 5-HT2 receptors

Currently, ketamine is the only legal psychedelic medicine available to mental health providers for the treatment of emotional suffering. Over the past several years, ketamine has come into psychiatric use as an intervention for treatment resistant depression (TRD), administered intravenously without a psychotherapeutic component. In these settings, ketamine's psychedelic effects are viewed as...

Psychedelic plants and fungi have been used in indigenous medicinal traditions for millennia. Modern psychedelic research began when Albert Hofmann first synthesized lysergic acid diethylamide (LSD-25) in 1938. Five years later, became the first person to ingest LSD.

Proceedings of the National Academy of Sciences March 13, 2019 Panos Zanos, Jaclyn N. Highland, Brent W. Stewart et al. 153 citations

Significance Despite available medications for depression, currently approved antidepressants take months to exert therapeutic effects, and ∼30% of patients remain treatment resistant. In contrast, a single subanesthetic dose of ketamine exerts rapid (within hours) and sustained antidepressant actions. Preclinical studies indicate that the ketamine metabolite ( 2R , 6R )-hydroxynorketamine [(...
