Silydianin holds profound significance due to its polyphenolic nature and diverse array of biological activities. Functioning as a modulator, silydianin is postulated to influence the behavior of several enzymes and proteins. Scientific investigations have revealed its potential to inhibit the activity of enzymes associated with inflammation, such as cyclooxygenase-2 (COX-2) and lipoxygenase (LOX). Furthermore, silydianin displays inhibitory effects on proteins that regulate cellular processes like proliferation and apoptosis, including Bcl-2 and caspase-3.
