General description

Indole-3-propionic acid can be obtained from tryptophan by deamination reaction.

Application

Reactant for preparation of:
  • Fluorescent analogues of strigolactones
  • Anti-tumor agents
  • Melanocortin receptors ligands
  • Immunosuppressive agents
  • Iinhibitors of hepatitis C virus
  • Histamine H4 receptor agonists
  • NR2B/NMDA receptor antagonists
  • CB1 antagonist for the treatment of obesity
  • Antibacterial agents
  • Inhibitor of TGF-β receptor binding
Indole-3-propionic acid may be used in the synthesis of oxindole-3-propionic acid via reaction with N-bromosuccinimide in acetic acid followed by treatment with H2/Pd catalyst.

Biochem/physiol Actions

Studied as an adjunct to improve perfusion after liver transplant.
