EMPO is a relative of DEPMPO that shows great efficiency in the spin trap of|in vitro|detection of O-, N-, S-, and C-centered free radicals, displaying a longer life than DMPO.
EMPOis a relative of DEPMPO that shows great efficiency in the spin trap detection of O-, N-, S-, and C-centered free radicals
EMPO is a hydrophilic cyclic nitrone analog of the free radical spin trap DMPO . The EMPO-superoxide adduct (EMPO-OOH) exhibits an ESR spectrum that is similar to the DMPO-OOH spectrum.However, the EMPO-OOH adduct is about 5-8 times more stable (t1/2 = 4.8 - 8.6 min) and does not spontaneously decay to the hydroxyl adduct, making spectral interpretation less difficult.
