EDTA bis-(ethyl phenylalaninate): A novel transition metal-Ion chelating hydroxyl radical scavenger with a potential anti-inflammatory role

Conjugation of ethylenediaminetetraacetic acid (EDTA) to ethyl phenylalaninate generates a novel radical scavenging metal-ion chelator EDTA bis-(ethyl phenylalaninate) (EBEP). The oxidation products o-, m- and p-tyrosine were isolated from hydrolysed, aqueous and aerated solutions containing EBEP, Fe(II) and H2O2. Data obtained demonstrate the potential of EBEP to act as a radical scavenging, iron-ion chelating antioxidant under physiologically relevant conditions.
