Silybin A: The Stereochemically Pure Powerhouse for Advanced Hepatoprotection & Oncology Research

1. What is Silybin A?

Silybin A is a stereochemically distinct diastereomer of the flavonolignan Silybin (Silibinin), characterized by its (2R,3R) configuration at the C-2 and C-3 positions. Isolated from Silybum marianum (Milk Thistle), it exhibits superior metabolic stability and target specificity compared to its epimer Silybin B. As the most biologically potent constituent of Silymarin, Silybin A demonstrates enhanced hepatocyte uptake እና stronger modulation of key signaling pathways (STAT3, PI3K/Akt) at nanomolar concentrations.
