General description

5-Hydroxyindole-2-carboxylic acid on oxidation with KMnO4 yields pyrrole-2,3,5-tricarboxylic acid.

Application

5-Hydroxyindole-2-carboxylic acid was used in HPLC-amperometric detection of serotonin in plasma, platelets and urine.
  • Reactant for preparation of indole C5-O-substituted seco-cyclopropylindole analogs as potential anticancer agents
  • Reactant for microwave combinatorial synthesis of indolic arylpiperazine derivatives as ligands for 5-HT1A, 5-HT2A, and 5-HT2C receptors
  • Reactant for preparation of melanins as novel nature-inspired radioprotectors
  • Reactant for preparation of 5-Hydroxyindole-2-carboxylic acid amides as histamine-3 receptor inverse agonists for the treatment of obesity
  • Reactant for preparation of conformationally constrained peptidomimetic inhibitors of signal transducer and activator of transcription 3 (Stat3)
