Indole-3-pyruvic acid, a keto analogue of tryptophan, is an orally active AHR agonist. Indole-3-pyruvic acid has antioxidant properties, and can be used in the research of inflammation, anxiety.
Indole-3-pyruvic acid (50 and 250 μM, 24 h) activates AHR in HepG2 cells[1]. Indole-3-pyruvic acid (50 μM, 4 days) does not inhibit Th1 cell differentiation but promotes Tr1 differentiation[1]. Indole-3-pyruvic acid (1 mM, 24 h) reduces UVB-induced cytotoxicity in HaCaT cells[1]. Indole-3-pyruvic acid (25 mM, 6 h) reduces the levels of COX-2 in HaCaT cells[2].
Indole-3-pyruvic acid (oral administration, fed in MF chow (0.1%) for 5 d) activates AHR in BALB/c mice[1]. Indole-3-pyruvic acid (oral administration, fed in MF chow (0.1%) for 5 wk) abrogates chronic inflammation in a T cell-mediated colitis model[1]. Indole-3-pyruvic acid (100 μM, dose at skin) protects against UVB-induced skin damage in HR-1 hairless mice[2]. Indole-3-pyruvic acid (intraperitoneal injection, 100-200 mg/kg) increases the time spent in the open arms of the elevated plus maze in mice[3].
