Application

6-Methoxyindole was used to study the fluorescence of protonated excited-state forms of serotonin and other related compounds in acid. It was used in the preparation of:
  • tryptophan dioxygenase inhibitors pyridyl-ethenyl-indoles, potential anticancer immunomodulator
  • indolylindazoles and indolylpyrazolopyridines, interleukin-2 inducible T cell kinase inhibitors
  • diindolyloxyindoles, anticancer agents
  • benzoylpiperazinyl-indolyl ethane dione derivatives, HIV-1 inhibitors
  • 3-aroylindoles as anticancer agents
  • indolyl and isoquinolinyl anthranilates, PPARδ partial agonists
  • heteroaryl ketones, VEGFR-2 inhibitors
  • Reactant for preparation of tryptophan dioxygenase inhibitors pyridyl-ethenyl-indoles as potential anticancer immunomodulators
  • Reactant for synthesis of indolylindazoles and indolylpyrazolopyridines as interleukin-2 inducible T cell kinase inhibitors
  • Reactant for preparation of diindolyloxyindoles as anticancer agents
  • Reactant for preparation of benzoylpiperazinyl-indolyl ethane dione derivatives as HIV-1 inhibitors
  • Reactant for preparation of 3-aroylindoles as anticancer agents
  • Reactant for preparation of indolyl and isoquinolinyl anthranilates as PPARδ partial agonists
  • Reactant for preparation of heteroaryl ketones as VEGFR-2 inhibitors

Biochem/physiol Actions

6-Methoxyindole inhibits the chlorinating activity of myeloperoxidase and inhibits the generation of hypochlorous acid released by activated leukocytes.

Hypochlorous acid (HOCl) released by activated leukocytes has been implicated in the tissue damage that characterizes chronic inflammatory diseases. In this investigation, 14 indole derivatives, including metabolites such as melatonin, tryptophan and indole-3-acetic acid, were screened for their ability to
