Tryptophan-derived indole compounds have been widely investigated as antioxidants and as free-radical scavengers. Indole-3-propionic acid (IPA), one of these compounds, is a deamination product of tryptophan. In the present study, we used Mongolian gerbils to investigate IPA's neuroprotective effects against

The antirepressor indole 3-propanoate has been shown by X-ray crystallography to bind in a different orientation compared with the natural corepressor for the tryp repressor, L-tryptophan (Lawson, C.L. & Sigler, P. B. (1988) Nature 333, 869-871). This suggests a simple

Aging is a multi-factorial process, however, it is generally accepted that reactive oxygen species (ROS) are significant contributors. Mitochondria are important players in the aging process because they produce most of the cellular ROS. Despite the strength of the free-radical

Chemiluminescence associated with oxidation by free radicals was investigated in an alkaline, hemin-catalysed hydrogen peroxide system, using the following tryptophan metabolites as radical scavengers: indole-3-pyruvic, indole-3-propionic, kynurenic, xanthurenic and quinaldic acids and 4-hydroxy-quinoline. Light emission from oxidation of the indolic

Two auxin amidohydrolases, BrIAR3 and BrILL2, from Chinese cabbage [Brassica rapa L. ssp. pekinensis (Lour.) Hanelt] were produced by heterologous expression in Escherichia coli, purified, and screened for activity towards N-(indol-3-ylacetyl)-L-alanine (IAA-Ala) and the long-chain auxin-amino acid conjugates, N-[3-(indol-3-yl)propionyl]-L-alanine (IPA-Ala)
