Reduction of ultraviolet light-induced oxidative stress by amino acid-based iron chelators.

Abstract

The generation of free radicals by ultraviolet (UV) light accelerates skin aging, which is known as photoaging. Cutaneous iron catalyzes the generation of free radicals. We designed novel antioxidants that suppressed the iron-catalyzed free radical generation and the ensuing UV-induced damage by mimicking the binding site of iron sequestering proteins… (More)
