Isosilybin A (Standard)

Isosilybin A (Standard) is the analytical standard of Isosilybin A (HY-N7043) . Isosilybin A is a PPARγ agonist that can be isolated from silymarin. Isosilybin A activates extrinsic and intrinsic pathways of apoptosis through targeting of the Akt-NF-kB-AR axis. Isosilybin A can relieve the inflammatory response in the rosacea model via inhibiting Erk and p38 signaling pathways and M1 macrophage polarization, with its targets related to RELA and VEGFA. Isosilybin A has anti-prostate cancer (PCA) activity[1][2][3].
