DEPMPO

Description

DEPMPO (157230-67-6) is a spin trap capable of detecting oxygen, nitrogen, sulfur and carbon-centered free radicals both in vitro and in vivo. DEPMPO is useful for distinguishing between superoxide-dependent pathways of hydroxyl radical generation, and those that are superoxide independent.

Chemical properties

DEPMPO is Pale Yellow Oil

The Uses of DEPMPO

DEPMPO is a spin trap useful as a probe for free radical formation during myocardial ischemia/reperfusion injury. An analogue of DMPO

The Uses of DEPMPO

DEPMPO is the most efficient spin trap for the in vitro detection of O-, N-, S- and C-centered free radicals both invitro and invivo. It has a longer life-time than DMPO and can distinguish between superoxide-dependent and independent mechanisms that lead to the hydroxyl radical. It is less lipophilic (Kp=0.16) than DIPPMPO.
