Clinical Persistence of Chlamydia trachomatis Sexually Transmitted Strains Involves Novel Mutations in the Functional αββα Tetramer of the Tryptophan Synthase Operon [PDF]

open access: yesmBio, 2019
Clinical persistence of Chlamydia trachomatis (Ct) sexually transmitted infections (STIs) is a major public health concern. In vitro persistence is known to develop through interferon gamma (IFN-γ) induction of indoleamine 2,3-dioxygenase (IDO), which ...

Indole contributes to tetracycline resistance via the outer membrane protein OmpN in Vibrio splendidus [PDF]

open access: yes, 2020
As an interspecies and interkingdom signaling molecule, indole has recently received attention for its diverse effects on the physiology of both bacteria and hosts. In this study, indole increased the tetracycline resistance of Vibrio splendidus.

Synthesis of Bis(3‐indolyl)methanes Mediated by Potassium tert‐Butoxide

open access: yesChemistryOpen, 2023
The indole moiety is an important N‐heterocycle found in natural products, and a key structural component of many value‐added chemicals including pharmaceuticals. In particular, bis(3‐indolyl)methanes (BIMs) are an important subgroup of indoles, composed

Relation between Mood and the Host-Microbiome Co-Metabolite 3-Indoxylsulfate: Results from the Observational Prospective NutriNet-Santé Study

open access: yesMicroorganisms, 2021
Gut microbiota metabolizes tryptophan into indole, which can influence brain and behavior. Indeed, some oxidized derivatives of indole, formed in the liver, have neuroactive properties, and indole overproduction by the gut microbiota induces an anxio ...
