5,11-Dihydroindolo[3,2-b]carbazole-6-carbaldehyde (cas: 172922-91-7) belongs to indole derivatives. Indole could be stereoselectively alkylated with chiral cyclopentyl sulfone reagent. Indole plays a fundamental role for QS in E. coli, being one of the signal molecules responsible for the transcription of a variety of genes (gabT, and tnaB ASTD). Category: indole-building-block

In vitro treatment of mouse and human cells with endogenous ligands for activation of the aryl hydrocarbon receptor was written by Yamada, Taisho;Takaoka, Akinori. And the article was included in Bio-Protocol in 2017.Category: indole-building-block This article mentions the following:

Activation of the aryl hydrocarbon receptor (AHR) by endogenous ligands has been implicated in a variety of physiol. processes such as cell cycle regulation, cell differentiation and immune responses. It is reported that tryptophan metabolites, such as kynurenine (Kyn) and 6-formylindolo(3,2-b)carbazole (FICZ), are endogenous ligands for AHR (Stockinger et al., 2014). This protocol is designed for treatment with Kyn or FICZ in mouse embryonic fibroblasts (MEFs) or primary peripheral monocytes. In the experiment, the researchers used many compounds, for example, 5,11-Dihydroindolo[3,2-b]carbazole-6-carbaldehyde (cas: 172922-91-7Category: indole-building-block).
