Novel membrane-localizing TEMPO derivatives for measurement of cellular oxidative stress at the cell membrane
摘要:
Oxidative stress affecting lipid membranes is considered to be closely related to cardiovascular disease and brain ischernia. In this study, we designed and synthesized membrane-localizing TEMPO derivatives and demonstrated that one of these synthesized probes, compound 1, localized and detected oxidative stress in the cell membrane in an endotoxic model of a mouse macrophage-like cell line. Compound I is therefore a potentially useful probe for evaluating oxidative. stress at the cell membrane. (c) 2006 Elsevier Ltd. All rights reserved.
