Isosilybin B (Standard)

Isosilybin B (Standard) is the analytical standard of Isosilybin B (HY-N7045) . This product is intended for research and analytical applications. Isosilybin B is a flavonolignan. Isosilybin B can be isolated from Silybum marianum. Isosilybin B can regulate cell cycle-related proteins (e.g., reduce cyclins (D3, D1, A, E), Cdk4, Cdk2, Cdc25A), and activate Caspases (Caspase-9 and Caspase-3) . Isosilybin B can promote Apoptosis, reduce androgen receptor (AR) and PSA. Isosilybin B has anticancer activity against prostate cancer[1][2].
