- Tabernanthalog Reduces Motivation for Heroin and Alcohol in a Polydrug Use Model (in rats, “TBG effectively reduced motivation for heroin and alcohol in this test, indicating its efficacy is preserved in animals with a history of heroin and alcohol polydrug use.“)
- The G protein biased serotonin 5-HT 2A receptor agonist lisuride exerts anti-depressant drug-like activities in mice (in mice, shows antidepressant but not hallucinogenic (head twitch response) for lisuride)
- 5-MeO-DMT induces sleep-like LFP spectral signatures in the hippocampus and prefrontal cortex of awake rats (in rats, “Our findings suggest that the psychoactive effects of classical psychedelics are associated with the integration of waking behaviours with sleep-like spectral patterns in LFPs.“)
- Systems-level analysis of local field potentials reveals differential effects of lysergic acid diethylamide and ketamine on neuronal activity and functional connectivity (in rats, “Our data suggest that the altered brain states of LSD and ketamine are caused by different underlying mechanisms, where LFP power shifts indicate increased neuronal activity but reduced connectivity following ketamine, while LSD also leads to reduced connectivity but without an accompanying change in LFP broadband power.“)
- The effect of lysergic acid diethylamide on brain BDNF levels and Pavlovian extinction learning in mice (in mice, thesis, related to recent findings on BDNF (tkbr receptor) publications, but “We did not observe statistically significant differences between the treatment groups in BDNF levels or behavioral experiments after the single LSD injections”)
- Underlying pharmacological mechanisms of psilocin-induced broadband desynchronization and disconnection of EEG in rats (in rats, “These findings suggest the involvement of all three serotonergic receptors studied as well as the role of dopaminergic mechanisms in power spectra/current density with only the 5-HT2A receptor being effective in both studied metrics.“)
- Systematic Characterization of LSD metabolites in C. elegans by ultra-high performance liquid chromatography coupled with high-resolution tandem mass spectrometry (in C. elegans, imaging of LSD metabolites)
- Retigabine promotes ketamine’s antidepressant effect in the forced swim test in male and female C57BL/6J mice (in mice, “When simultaneously gave retigabine, ketamine’s antidepressant effect in the forced swim test was significantly enhanced with a prolonged effective duration.”)
- The Kappa Opioid Receptor Agonist 16-Bromo Salvinorin A Has Anti-Cocaine Effects without Significant Effects on Locomotion, Food Reward, Learning and Memory, or Anxiety and Depressive-like Behaviors (in mice, “These findings highlight that G-protein-biased structural analogues of SalA can have improved pharmacokinetic profiles and fewer side effects while maintaining their anticocaine effects.“)
- L-Carnitine Prevents Behavioural Alterations in Ketamine-Induced Schizophrenia in Mice: Possible Involvement of Oxidative Stress and Inflammation Pathways (in mice, “These data provided evidence that, due to the antioxidant and anti-inflammatory effects of l-carnitine, it has a neuroprotective effect on mice model of schizophrenia.“)

- Biosynthesis of psilocybin and its nonnatural derivatives by a promiscuous psilocybin synthesis pathway in Escherichia coli (chemistry, psilocybin production)
- Psilocybin decelerates cellular senescence (in cells, psilocybin as anti-ageing agents, “Overall, these data are the first experimental evidence suggesting that psilocybin may decelerate the process of cellular senescence.“)
- Neurotoxic effects of hallucinogenic drugs 25H-NBOMe and 25H-NBOH in organotypic hippocampal cultures (in cells, “25H-NBOMe and 25H-NBOH disrupt the balance between neurogenesis and neuronal death in the hippocampus and, although chemically similar, have distinct neurotoxicity mechanisms.“)
- DM506 (3-Methyl-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole fumarate), a Novel Derivative of Ibogamine, Inhibits α7 and α9α10 Nicotinic Acetylcholine Receptors by Different Allosteric Mechanisms (in cells, “his study shows for the first time that DM506 inhibits both α9α10 and α7 nAChR subtypes by novel allosteric mechanisms likely involving modulation of the extracellular-transmembrane domain junction and cytoplasmic domain, respectively, but not by direct competitive antagonism or open channel block.“)
