Silydianin is a flavonolignan from Silymarin, which is the major constituent of milk thistle extract. Silydianin, an active constituent of Silybium marianum, have inhibitory properties against the P2Y12 receptor and block ADP-induced blood platelet activation. Silydianin has antiinflammatory activity, it regulates caspase-3 activation, affects cell membranes and acts as a free radical scavenger. Silydianin non-competitively inhibits the lipoxygenase from soybeans in vitro. It also inhibits the formation of prostaglandins in vitro.

Sample Use Guides
When polymorphonuclear neutrophils were cultured with 100 uM silydianin for 24 h, caspase-3 was activated. Induction of apoptosis by silydianin was accompanied by a decrease in luminol-enhanced chemiluminescence as well as superoxide radical (O2*-) release in freshly isolated cells and lipid peroxidation in mouse spleen microsomes.
