Catalytic repertoire of bacterial bisindole formation
Current Opinion in Chemical Biology, 2016Bacterial bisindole alkaloids that derive from the oxidative dimerization of l-tryptophan possess diversified biological activities and unique molecular structures. In recent years, the number of bisindoles and their gene clusters has greatly expanded, revealing a large genetic toolbox for the generation of unique structural modifications.

Enantioselective Synthesis of N−N Bisindole Atropisomers
Angewandte Chemie, 2022AbstractN−N Atropisomers are a common motif in natural products and represent a significant dimension for exploration in modern pharmaceutical and medicinal chemistry. However, the catalytic atroposelective synthesis of such molecules remains challenging, hampering meaningful development.

Bisindole alkaloids from Tabernaemontana corymbosa
Phytochemistry, 2018Continued study in bioactive monoterpenoid alkaloids led to the isolation of nine undescribed alkaloids, taberyunines A-I, together with 32 known ones from the aerial parts of Tabernaemontana corymbosa Roxb. ex Wall (Apocynaceae). Among the undescribed alkaloids, taberyunines A-G and H-I were assigned to Aspidosperma-Aspidosperma and Vobasinyl-Ibogan ...

Synthesis of a novel series of cytotoxic bisindole alkaloids
Bioorganic & Medicinal Chemistry Letters, 2001Original cytotoxic bisindole alkaloids with a 1,2,3,4-tetrahydroquinoline bridge were synthesized by reductive amination with various anilines. The most cytotoxic compounds display a high and dose-dependent cell cycle effect with accumulation in the G1 phase.

Synthesis of Marine Sponge Bisindole Alkaloids Dihydrohamacanthins
Organic Letters, 2002[structure: see text] A convergent synthesis of the marine sponge bisindole alkaloids dihydrohamacanthins is described. The synthesis centers on the construction of 3,5- and 3,6-linked pyrazinones and their reduction to the requisite piperazinones with sodium cyanoborohydride.

Chemistry of Heterocyclic Compounds, 1993
Reaction of 2,2′-diethoxycarbonyl-bis(5-indolyl)sulfone with benzaldehyde gave an active dibromide — 2,2′diethoxycarbonyl-3,3′-di(bromobenzyl)bis(5-indolyl)sulfone; derivatives of di(bisindolyl)phenylmethane have been prepared by condensation of 2,2′-diethoxycarbonyl-bis (N-methyl-5-indolyl)sulfone with benzaldehyde and p-methoxybenzaldhyde.
