The Chemistry of Indoles. XXIV. Syntheses of 3-Indoleacetic Acid and 3-Indoleacetonitrile Having a Halogeno Group and a Carbon Functional Group at the 4-Position [PDF]

, 1985
Various 4-halogeno-3-indoleacetic acids and -3-indoleacetonitriles were synthesized for the first time by means of the Sandmeyer or Schiemann reaction, demonstrating the versatility of 4-indolediazonium salts in 4-substituted indole chemistry.

Human Fecal Microbiota Transplantation Reduces the Susceptibility to Dextran Sulfate Sodium-Induced Germ-Free Mouse Colitis

Frontiers in Immunology, 2022
In clinical practice, fecal microbiota transplantation (FMT) has been used to treat inflammatory bowel disease (IBD), and has shown certain effects. However, the selection of FMT donors and the mechanism underlying the effect of FMT intervention in IBD ...

Copper-Mediated Cyclization of o‑Hydroxyaryl Enaminones with 3‑Indoleacetic Acids toward the Synthesis of 3‑Indolmethyl-Chromones

, 2022
Here, we describe a copper-mediated tandem decarboxylative coupling/annulation protocol of o-hydroxyaryl enaminones with 3-indoleacetic acids. A series of 3-indolmethyl-chromones were afforded in up to 97% yield.

Whole Grain Qingke Attenuates High-Fat Diet-Induced Obesity in Mice With Alterations in Gut Microbiota and Metabolite Profile

Frontiers in Nutrition, 2021
Whole grain Qingke (WGQK) displays anti-obesity and lipid-lowering properties; however, the underlying mechanism remains elusive. This study investigated the alteration of gut microbiota composition and metabolite profile induced by WGQK intervention in ...

Tryptophan-centered metabolic alterations coincides with lipid-mediated fungal response to cold stress

Heliyon, 2023
Tryptophan and its derived metabolites have been assumed to play important roles in the development and survival of organisms. However, the links of tryptophan and its derived metabolites to temperature change remained largely cryptic.
