Journal ArticleDOI
Monoamine oxidase inhibitors in South American hallucinogenic plants: tryptamine and beta-carboline constituents of ayahuasca.
TL;DR: The levels of DMT and beta-carbolines found in the ayahuasca samples examined in the present study were an order of magnitude greater than the levels reported in a previous study, which indicated that their effects in combination are additive, rather than synergistic or antagonistic.
Journal ArticleDOI
Clinical investigations of the therapeutic potential of ayahuasca: rationale and regulatory challenges.
TL;DR: Ayahuasca is a hallucinogenic beverage that is prominent in the ethnomedicine and shamanism of indigenous Amazonian tribes as discussed by the authors and is used as a sacrament by several syncretic churches.

Photoredox activation and anion binding catalysis in the dual catalytic enantioselective synthesis of β-amino esters
Giulia Bergonzini,Corinna S. Schindler,Carl-Johan Wallentin,Eric N. Jacobsen,Corey R. J. Stephenson +4 more
TL;DR: The enantioselective oxidative C-H functionalization of tetrahydroisoquinoline derivatives is achieved through the merger of photoredox and asymmetric anion-binding catalysis and introduces a potentially general approach to asymmetric transformations in oxidative photocatalysis.
Journal ArticleDOI
Antialgal, antibacterial and antifungal activity of two metabolites produced and excreted by cyanobacteria during growth.
Rainer-B. Volk,Franz H. Furkert +1 more
TL;DR: The antimicrobial activity of two cyanobacterial exometabolites, norharmane (9H-pyrido(3,4-b)indole) and 4,4'-dihydroxybiphenyl, was determined in suspension assays and the natural function as allelopathic chemicals and a possible applicability as antifouling agents or leads for the development of new antIFouling chemicals are discussed.
Journal ArticleDOI
Exposure to beta-carbolines norharman and harman.
W. Pfau,Kerstin Skog +1 more
TL;DR: The literature data on levels of norharman and harman in fried meat and fish, meat extracts, alcoholic drinks, and coffee brews is summarized to indicate that inhalative exposure leads to a rapid increase in plasma levels and high bioavailability of norHarman and Harman and there are indications that sublingual absorption may increase dietary uptake of beta-carbolines.

Die Identität des Aribins mit dem Harman
TL;DR: Aribin bildet farblose Krystalle, welche wasserfrei bei 229 bei as discussed by the authors, ohne Zersetzung schmelzen und dann wieder krystallinisch erstarren.

Isolement et identification de deux β‐carbolines dans la racine de chicorée torréfiée
Arlette Proliac,Maurice Blanc +1 more
TL;DR: Two β-carbolines, harman and norharman, have been isolated from roasted chicory roots by solvent extraction and chromatography on alumina as discussed by the authors, and they were identified by chromatographic and spectroscopic techniques in comparison with reference compounds.
