Seselin is primarily used in pharmaceutical and biological research due to its bioactive properties. It exhibits anti-inflammatory and antioxidant activities, making it a candidate for studying neurodegenerative diseases and aging-related conditions. Research also explores its potential as an anticancer agent, where it has shown inhibitory effects on certain tumor cell lines by inducing apoptosis and cell cycle arrest. Additionally, seselin acts as a precursor in the synthesis of other biologically active compounds, enhancing its value in drug development. Its ability to modulate enzyme activity, particularly in cytochrome P450 enzymes, contributes to studies on drug metabolism and interactions. Furthermore, it demonstrates antimicrobial activity against certain fungi and bacteria, with potential applications in natural pharmaceuticals and cosmetics.
