Dennis McKenna: Beyond Ayahuasca - Occurrence & Biological Activities of Natural ß-carbolines

Beta-carbolines are central, potent compounds beyond their well-known role in ayahuasca. They serve as selective monoamine oxidase A inhibitors that facilitate the absorption of orally inactive dimethyltryptamine. Beyond this, these naturally occurring alkaloids display significant structural and biological diversity as potent modulators of various receptors across many biological systems. Tetrahydroharmine is a key substance featured for its multi-faceted properties, including selective serotonin reuptake inhibition and direct stimulation of neural stem cell proliferation. Research highlights the potential of beta-carboline analogues in targeting neurodegenerative conditions such as Alzheimer's, as well as mitigating the cellular impact of certain conditions via specific kinetic interactions.
