Demethylmangostinin is primarily studied for its biological activities, particularly its anti-inflammatory and antioxidant properties. It has shown potential in inhibiting key enzymes involved in inflammatory pathways, making it a candidate for development in treatments for chronic inflammatory conditions. Research also indicates antimicrobial and anticancer effects, with studies observing growth inhibition in certain cancer cell lines through induction of apoptosis and cell cycle arrest. Due to its natural origin and low toxicity profile, it is being explored as a lead compound in nutraceuticals and phytopharmaceuticals. Additionally, its antioxidant capacity supports its use in formulations aimed at reducing oxidative stress-related damage, with possible applications in skincare and neuroprotective agents.
