Urolithin A Biological Activity
| Description | Urolithin A is an intestinal metabolite of ellagic acid with antioxidant and antiproliferative effects; inhibits T24 and Caco-2 cell growth with IC50 values of 43.9 and 49 μM, respectively. |

| In Vitro | Urolithins could mainly inhibit prostate cancer and colon cancer cell growth. Urolithin A increases mRNA and protein expression of Phospho-p38 MAPK, and decreases mRNA and protein expression of MEKK1 and Phospho-c-Jun in T24 cells. Caspase-3 is also activated and PPAR-γ protein expression increased in drug-induced apoptosis[1]. Urolithin A exerts a dose- and time-dependent significant arrest at G2/M and S phases after treatments with 50 and 100 μM at 24 and 48 h compared to control cells. It induces cell apoptosis with 50 and 100 μM [2]. Urolithin A shows potent antiproliferative activity on HepG2 cells. When cell death is induced by Urolithin A, the expression of β-catenin, c-Myc and Cyclin D1 are decreased and TCF/LEF transcriptional activation is notably down-regulated. Urolithin A also increases protein expression of p53, p38-MAPK and caspase-3, but suppresses expression of NF-κB p65 and other inflammatory mediators[3]. |

| In Vivo | The volume of paw edema is reduced at 1 h after oral administration of urolithin A. In addition, plasma in treated mice exhibited significant oxygen radical antioxidant capacity (ORAC) scores with high plasma levels of the unconjugated form at 1 h after oral administration of urolithin A[4]. |
|---|
| Cell Assay | Human colon cancer cells HT-29 are treated for 24 and 48 h at 100 and 50 μM of Urolithin A and Iso Urolithin A aglycones and their glucuronide conjugates. Cell viability and proliferation are measured using a TC10 automated cell counter with the addition of Trypan blue for viability determination. IC50 values are determined by MTT assay[2]. |

| Animal Admin | Mice: Paw edema is induced in the right hind paw of ICR mice by the subcutaneous injection of 1% λ-carrageenan in pysiological saline (50 μL). The inflammation level is quantified by the volume of paw edema. Urolithin A dissolved in 0.5% carboxymethylcellulose suspension is orally administered to the mice at 1 or 6 h before carrageenan injection. The anti-inflammatory effects of urolithin A on carrageenan-induced edema in mice are analyzed[4]. |
