Background:
Indole-3-pyruvic acid is an endogenous metabolite of tryptophan and intermediate in the biosynthesis of the major auxin hormone, indole-3-acetic acid , in plants.[1][2][3]?Indole-3-pyruvic acid (50 and 250 µM) activates the aryl hydrocarbon receptor (AhR) in a reporter assay.[1]??It reduces UVB-induced cytotoxicity and the levels of COX-2 in HaCaT keratinocytes.4Topical administration of indole-3-pyruvic acid (100 µmol) reduces the severity of UVB-induced damage in mouse skin. Dietary administration of indole-3-pyruvic acid (0.1%) reduces diarrhea, colonic inflammation, and the colonic expression ofIl1b,Ifng,Tnfa, andIl12bin a mouse model of T cell-mediated colitis.[1]??It increases the time spent in the open arms of the elevated plus maze in mice when administered at a dose of 100 mg/kg.[2]??It also reverses the anxiogenic effect of caffeine and 3-hydroxy kynurenine, but not pentylenetetrazole or phenylethylamine, in the elevated plus maze in mice.
