1H-Indole-3-propanoic acid

Description3-Indolepropionic 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.

Uses3-Indolepropionic acid is a deamination product of Tryptophan (T947200) that protects the hippocampus (studied in gerbils) from ischemic damage and oxidative stress. It’s ability to protect the neurons in this way is attributed to its potent antioxidative effects. 3-Indolepropionic acid is also hypothesized to have protective effects on the thyroid gland.

General Description3-Indolepropionic acid is an effective inhibitor of aggregation of misfolded β-amyloid protein (Abeta). Three-component one-pot procedure has been reported to assemble 3-indolepropionic acids.
