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
