Description and Uses

Indole-3-propionic acid is a bacterial metabolite that has antioxidant and neuroprotective activities. It scavenges ABTS radicals in a cell-free assay when used at concentrations ranging from 50 to 150 μM and decreases hydrogen peroxide-induced malondialdehyde (MDA) levels in rat striatal membranes (IC₅₀ = 180 μM). Indole-3-propionic acid also decreases increases in MDA levels induced by amyloid β (1-42) in PC12 cells. It decreases ischemia-induced increases in cell death of pyramidal neurons and levels of 4-hydroxy nonenal (HNE; ) and glial fibrillary acidic protein (GFAP) in the hippocampal CA1 region in gerbils when administered at a dose of 10 mg/kg per day.

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.
