Background:

Wogonin is a naturally occurring mono-flavonoid, can inhibit the activity of CDK8 and Wnt, and exhibits anti-inflammatory and anti-tumor effects.

Wogonin (0-200 μM) exhibits a dose- and time- dependent reduces in cell viability of caco-2, SW1116 and HCT116 cells. Wogonin (10-40 μM) induces G1 phase arrest in HCT-116 cells. Wogonin also supresses Wnt signaling pathway in HCT116 cells. Wogonin interfers in the activity of transcription factor TCF/Lef family. Moreover, Wogonin inhibits β-catenin-mediated transcription through suppressing the activity of CDK8[1]. Wogonin shows cytotoxic and antiproliferative effects on HeLa cells. Wogonin (90 μM) induces cell cycle arrest at G0-G1 phase, and suppresses the levels of cyclin D1 and Cdk4 markedly in HeLa cells[2]. Wogonin (1.25, 2.5, 5, 10, 20 μg/ml) suppresses EtOH-induced inflammatory response in RAW264.7 cells[3].

Wogonin (30, 60 mg/kg) reduces tumor growth of HCT116 cells in a xenograft model[1]. Wogonin (25, 50, 100 mg/kg) protects against liver injury and pathological characteristics of ALD in mice. Wogonin activates PPAR-γ expression in mice with ALD and EtOH induced RAW264.7 cells[3].
