I am currently working on prospects on molecular structure modification and tweaking of readily available compounds that are well-known good antioxidants in various in vitro assays. The goal is to modify the structures, synthesize them, and then assess the activities of the derivatives. Now, I am trying to find some understudied yet promising compounds that exhibit superior antioxidant capacity and has wide structural variability . I was wondering if anyone can suggest any understudied compounds and derivatives I can start with? Some literature and supporting articles would be a great help. Thanks
