Abstract

Abstract New photochemical studies of the reactivity of biopterin (BPT) and neopterin (NPT) in acidic (pH= 5.5) and alkaline (pH= 10.5) aqueous solutions at 350 nm and room temperature were performed. The photochemical properties of BPT are of particular interest because the photolysis of this compound takes place in the white skin patches of patients affected by vitiligo. The photochemical reactions were followed by UV/VIS ...
