Silychristin (Silicristin) is a plant growth regulator. Silychristin is an anti-hepatotoxic agent. Silychristin is the inhibitor of horseradish peroxidases and lipoxygenase.

Silydianin (Silidianin) exerts inhibition of UGT in human liver. Silydianin exerts inhibition of OATP1B1, OATP1B3 (unknown origin) expressed in HEK293 cells. Silydianin exerts inhibition of OATP2B1 (unknown origin) expressed in MDCK2 cells.

Isosilybin A is a partial PPARγ agonist, it significantly induced ABCA1 protein expression, it inhibited both monophenolase (IC50=1.7-7.6μM) and diphenolase (IC50=12.1-44.9μM) of tyrosinase. Isosilybin A shows anti-angiogenic efficacy, it has anti-prostate cancer (PCA) activity that is mediated via cell cycle arrest and apoptosis induction.

Silyamandin may have antihepatotoxic and chemopreventive activities.

Silychristin B is a natural product for research related to life sciences. The catalog number is TN5023 and the CAS number is 879325-58-3.
