Background:

Tempol is a superoxide scavenger (superoxide dismutase mimetic). It is a member of non-thiol-containing radiation protectors that can permeate the membrane.


In vitro, Tempol disrupted H2O2-mediated reduction in mitochondrial respiration and increase in LDH secretion from rat PT cells, suggesting in a decrease in cell injury and death, [1]. In human prostate cancer cell, Tempol activated uPAR (urokinase receptor) [2].


In vivo, Tempol treatment showed 1) renal function and injury improvement 2) PMN infiltration and lipid peroxidation reduction 3) reduced nitrosative and oxidative stress [1]. In cirrhotic rats, Tempol decreased portal pressure and raised portal blood flow [3]. In 2K1C rats, Tempol inhibited upregulation of TGF-beat and MMPs, and prevented changes of cardiac hypertensive [4]. It also prevented cerebral vessel remodeling in hypertensive rats [5].
