Electrochemical and esr spin trap studies of a new iron tetra-catecholamide complex.

Abstract:

:A new siderophore, N5,N6-thiodipropanoyl-bis[N1,N10-bis(2,3-dihydroxy benzoyl-spermidine)]-Fe (III) complex or H2LFe has been synthesised. The reaction of the reduced form of this complex with dioxygen has been investigated through electrochemical study and revealed the formation of a new species assumed to be H2O2. This species has been confirmed by esr spectroscopy using the diamagnetic compound 5-deutero-2,2,5-trimethylpyrrolidine-1-hydroxyl as spin trap. The resulting persistent radical is 5-deutero-2,2,5-trimethylpyrrolidine-1-yloxy (aN = 16.58 G, aD = 3.49 G).
