Tectochrysin is a flavone compound primarily studied for its potential biological and pharmacological applications, including in cosmetics and skincare. It exhibits anti-inflammatory properties by inhibiting key inflammatory mediators such as cytokines and enzymes like COX-2, which may help reduce skin irritation. Its antioxidant effects help reduce oxidative stress, protecting against environmental damage like pollution and potentially slowing skin aging by inhibiting wrinkle-related enzymes. Research suggests anticancer activity through induction of apoptosis and suppression of tumor cell proliferation, particularly in breast and liver cancer cells. Additionally, tectochrysin shows neuroprotective potential in models of brain injury and neurodegenerative conditions due to its ability to cross the blood-brain barrier. It also demonstrates antimicrobial activity against certain pathogens. Most applications remain in the preclinical research stage, with potential for development into active ingredients in health products, cosmetics, or therapeutics.
