An Improved Synthesis of α-Carbolines under Microwave Irradiation

open access: yes, 2016
α-Carbolines are interesting core structures for designing DNA-interacting small molecules. However, these compounds are not commercially available and their synthetic methods are low yielding or time consuming. The shortest synthetic route, the modified

Inhibition of Monoamine Oxidase from Bovine Retina by β-Carbolines

open access: yes, 1994
The behaviour of some β-carboline derivatives as inhibitors of monoamine oxidase has been studied in bovine retina. Inhibition was found not to show any significant time dependence.

A QSAR study of a series of beta-carbolines.

open access: yes, 1989
The relationship between chemical structure and biological activity of a series of beta-carbolines is studied. A chromatographic system based on Thin Layer Chromatography is used to experimentally determine lipophilicity of the investigated beta ...

Modulation of GABA-stimulated chloride influx by beta-carbolines in rat brain membrane vesicles

open access: yes, 1988
We have shown that GABA-stimulated chloride influx into membrane vesicles from the rat cerebral cortex can be enhanced or inhibited by β-carbolines.

Biocatalytic asymmetric formation of tetrahydro-β-carbolines

open access: yes, 2010
Strictosidine synthase triggers the formation of strictosidine from tryptamine and secologanin, thereby generating a carbon-carbon bond and a new stereogenic center.

Metal free one pot synthesis of β-carbolines via a domino Pictet-Spengler reaction and aromatization

open access: yes, 2019
A convenient and efficient metal free, atom economical flexible synthesis of β-carbolines involving a domino Pictet-Spengler reaction and aromatization in oxygen atmosphere in N-methyl-2-pyrollidone (NMP) is described.

Oxidation of Tetrahydro-β-carbolines by Persulfate

open access: yes, 2019
The development of persulfate-mediated oxidation of tetrahydro-β-carbolines is reported. This mild reaction facilitates the formation of a variety of 2-formyl N-substituted tryptamines and the related derivatives as key intermediates in moderate to ...

Catalytic enantioselective nitrone cycloadditions enabling collective syntheses of indole alkaloids

open access: yesNature Communications
Tetrahydro-β-carboline skeletons are prominent and ubiquitous in an extraordinary range of indole alkaloid natural products and pharmaceutical compounds. Powerful synthetic approaches for stereoselective synthesis of tetrahydro-β-carboline skeletons have
