Abstract
The interactions of oxidative radicals (Br2−‐, HO− etc.) with N‐phosphoryl dipeptide derivatives (NDM‐TrpOMe and NDT‐MetOMe) have been investigated by using pulse radiolysis at different pH values. It has been found that Br2−‐ and HO− radicals oxidize the Met‐site and Trp‐site in the dipeptide derivatives via formation of the three‐electron‐bonded intermediate and indolyl radical simultaneously. Then the intramolecular electron transfer along the peptide backbone occurs. The rate constants of electron transfer, k, have been determined and the reaction mechanism has been deduced.
