  • Inflammation suppressor. Tryptophan metabolite produced by human microbiota (intestinal commensale Peptostreptococcus sp.). Involved in keeping the intestinal barrier intact and works as anti-inflammatory molecule. Patients with Inflammatory Bowel Disease (IBD) have an altered microbiota, with less Peptostreptococcus sp., and therefore reduced production of trans-indole-3-acrylic acid.
  • Chromophoric L-Trp analog used to probe the allosteric properties of the internal aldimine of tryptophan synthase. Also shown to be a moderate inhibitor of tryptophan synthase, trypothan-2,3-dioxygenase (TDO), indoleamine-2,3-dioxygenase (IDO), L-dopachrome isomerase and xanthine oxidase.
  • Reagent used as a matrix for MALDI-TOF mass spectroscopy in order to characterize and analyze polyphenols and synthetic polymers.
  • Used as heterocyclic building block or intermediate for the synthesis of indolyl acrylamide-derived inhibitors, pharmaceuticals or agrochemicals.
