Abstract

The trapping of superoxide anion with DMPO† and DEPMPO† has been carried out in the presence of a methylated β-cyclodextrin, Me-β-CD†; inclusion of the spin adducts in the cavity of Me-β-CD resulted in a seven-fold increase of their half-life (t1/2 = 96 min for DEPMPO-superoxide spin adduct) and in their protection towards glutathione peroxidase (Gpx) and also ascorbate anion in the case of DEPMPO.
