Monoamine Oxidase Inhibition by Plant-Derived β-Carbolines; Implications for the Psychopharmacology of Tobacco and Ayahuasca
Frontiers in Pharmacology – May 02, 2022
Summary
Ayahuasca, a traditional Amazonian brew, contains β-carboline alkaloids like harmine that inhibit monoamine oxidases (MAOs), crucial enzymes in brain chemistry. In studies involving various plants, these alkaloids may enhance neurogenesis and exhibit antidepressant properties while increasing the bioavailability of the hallucinogen N,N-dimethyltryptamine (DMT). Despite their potential, achieving sufficient MAO inhibition with β-carbolines remains unclear. Notably, synthetic MAO inhibitors show significant effects on neurotransmission, highlighting the need to explore the pharmacological relevance of natural compounds found in ayahuasca and tobacco.

Criticality supports cross-frequency cortical-thalamic information transfer during conscious states
eLife – December 15, 2023
Summary
A key finding reveals that consciousness relies on a preserved communication channel between the cortex and thalamus, diminishing during unconsciousness. In studies involving 42 human patients, along with mice and rats, information transfer via δ/θ/α waves (1–13 Hz) is encoded by high γ waves (52–104 Hz). Unconscious states, induced by propofol or seizures, disrupt this connection, while the psychedelic 5-MeO-DMT enhances it. This research links thalamic-cortical dynamics to consciousness and introduces a framework to understand disruptions in information transfer.
Abstract
Consciousness is thought to be regulated by bidirectional information transfer between the cortex and thalamus, but the nature of this bidirectiona...
Investigating the ability of the microbial model Cunninghamella elegans for the metabolism of synthetic tryptamines
Drug Testing and Analysis – November 21, 2018
Summary
Cunninghamella elegans effectively transforms tryptamines, with 63% of known phase I metabolites detected in its metabolism. This study examined four tryptamines, including the well-known N,N-Dimethyltryptamine (DMT), over 72 hours. Utilizing advanced liquid chromatography–mass spectrometry, researchers identified key metabolic pathways such as hydroxylation and demethylation. Notably, C. elegans produced unique metabolites not previously documented. These findings highlight the fungus's potential as a valuable model for studying the biochemistry of both natural and synthetic tryptamines, crucial for understanding their influence on brain disorders and behavior.

Ayahuasca: el encuentro de dos paradigmas.
Revista de Neuro-Psiquiatría – March 31, 2014
Summary
Ayahuasca, a powerful psychoactive substance from the Amazon rainforest, is revered by local cultures for its spiritual and medicinal properties. Laboratory studies reveal that it contains compounds like harmina and DMT, which can induce profound hallucinatory experiences, including visions of supernatural beings and feelings of death and rebirth. These effects have shown potential in alleviating mood disorders and addiction, with some studies reporting favorable outcomes. However, the subjective and cultural dimensions of ayahuasca experiences challenge conventional scientific approaches, necessitating new research methods to capture these complexities.

The intracranial injection of drugs in goldfish. I: Hallucinogens and their antagonism to smooth muscle activity
Journal of Asthma Research – January 01, 1979
Summary
Goldfish injected with hallucinogens like LSD and 5-MEO-DMT exhibited significant behavioral changes, confirming their pharmacological activity. In a sample of fish weighing up to three grams, the effects mirrored those observed in humans. Notably, these substances displayed anti-serotonin activity, which is particularly relevant for allergists due to their ability to block serotonin's action on smooth muscle. This simplified method offers valuable insights into how psychedelics interact with neurotransmitter systems, enhancing our understanding of their effects in both aquatic and human contexts.
