Desmethylglycitein (4',6,7-Trihydroxyisoflavone), a metabolite of daidzein, sourced from Glycine max with antioxidant, and anti-cancer activities. Desmethylglycitein binds directly to CDK1 and CDK2 in vivo, resulting in the suppresses CDK1 and CDK2 activity^[1]. Desmethylglycitein is a direct inhibitor of protein kinase C (PKC)α, against solar UV (sUV)-induced matrix matrix metalloproteinase 1 (MMP1)^[2]. Desmethylglycitein binds to PI3K in an ATP competitive manner in the cytosol, where it inhibits the activity of PI3K and downstream signaling cascades, leading to the suppression of adipogenesis in 3T3-L1 preadipocytes^[3]. In Vitro: Desmethylglycitein (4',6,7-Trihydroxyisoflavone)(0-100 μM; 24-72 hours) suppesses anchorage-dependent growth of HCT-116 and DLD1 cells in a dose- and time-dependent manner without cytotoxicity ^[1].
Desmethylglycitein (4',6,7-Trihydroxyisoflavone)(0-100 μM; 24-72 hours) suppresses CDK1 activity in a dose-dependent manner and inhibits CDK2 activity in HCT-116 cells^[1].
Desmethylglycitein (4',6,7-Trihydroxyisoflavone)(0-100 μM; 24-72 hours) induces cell cycle arrest at the S and G2/M phases, the percentage of cells in S phase is higher in the 100 μM 6,7,4′-THIF-treated group, and the same pattern is observed in G2/M phase (29.5% versus 19.1% ) ^[1].
In Vivo: Desmethylglycitein (4',6,7-Trihydroxyisoflavone) (intraperitoneally injection; 5 or 25 mg/kg; once daily; 20 days) suppresses tumor development in mice and serves as an effective anticancer treatment with the potential to inhibit or delay the tumorigenicity of HCT-116 cells in an in vivo system^[1].
