体外研究 (In Vitro) | 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].
RT-PCR[2] Cell Line: | HaCaT cells | Concentration: | 5-25 mM | Incubation Time: | 6 h | Result: | Inhibited UVB-stimulated mRNA expression of IL-1β, IL-6, and cyclooxygenase 2 (Cox-2). |

体内研究 (In Vivo) | 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].
Animal Model: | BALB/c mice[1] | Dosage: | Fed in MF chow.0.1% for 5 d | Administration: | Oral administration | Result: | Up-regulated the expression of Cyp1a1 (a biomarker for AHR activation) in the colon. |
Animal Model: | T cell–mediated colitis model of SCID mice[1] | Dosage: | Fed in MF chow.0.1% for 5 wk | Administration: | Oral administration | Result: | Suppressed diarrhea and improved colon inflammation. Down-regulated the expression of Th1 and proinflammatory cytokines and upregulated the expression of IL-10 in the colon. |
Animal Model: | HR-1 Hairless Mice[2] | Dosage: | 100 μM | Administration: | Dose at skin | Result: | Enhanced the epidermal thickness. Attenuated UVB-induced necrosis observed in upper layer of dermis. |
