1 The trapping of superoxide anion with DMPO and DEPMPO has been carried out in the presence of a methylated beta-cyclodextrin, Me-beta-CD; inclusion of the spin adducts in the cavity of Me-beta-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 ascrobate anion in the case of DEPMPO. ascrobate anion spindlin 1 Homo sapiens
