Beschreibung

Allgemeine Beschreibung

Indole-5-carboxylic acid is an indole derivative. On electropolymerization, it affords electroactive polymer film of poly(indole-5-carboxylic-acid). Different concentrations of indole-5-carboxylic acid in sulfuric acid solution has been investigated for the preventive action against mild steel corrosion. On electropolymerization it affords a trimeric product. Characterization studies of the trimeric product by ¹H NMR and various one- and two-dimensional NMR techniques have been reported.

Anwendung

• Reactant for preparation of tryptophan dioxygenase inhibitors pyridyl-ethenyl-indoles, as potential anticancer immunomodulators
• Reactant for preparation of indolyl-quinolines via metal- and solvent-free autoxidative coupling reaction
• Reactant for preparation of anthranilic acids using bromamine-B oxidant and palladium chloride catalyst
• Reactant for synthesis of indirubin derivatives
• Reactant for preparation of amide conjugates with ketoprofen, as inhibitors of Gli1-mediated transcription in Hedgehog pathway
• Reactant for preparation of piperazine-bisamide analogs as human growth hormone secretagogue receptor antagonists for treatment of obesity

Indole-5-carboxylic acid is the suitable reagent used to study the intramolecular excited state proton transfer in indole-2-carboxylic acid and indole-5-carboxylic acid in various solvents in acidic, basic, and neutral media by steady state and time resolved fluorescence spectroscopy. It may be used in the electrochemical synthesis of poly(indole-5-carboxylic acid) (PICA) films.
