Mechanism of dioxindolylalanine formation by singlet molecular oxygen-mediated oxidation of tryptophan residues.

Graziella Eliza Ronsein1, Mauricio Cesar Bof de Oliveira, Marisa Helena Gennari de Medeiros, Paolo Di Mascio.   

Abstract

The singlet molecular oxygen-oxidation of tryptophan generates diastereoisomeric dioxindolylalanine (diOia) along with hydroperoxides, alcohols and carbonyl compounds. Mechanistic investigations based on isotopic labeling and MS/MS analyses support diOia formation through a dioxetane intermediate.
