Application

Spin label reagent used in the chatacterization of antagonist and agonist binding sites of NK1 receptor. Also used to measure reactive oxygen generation in heart muscle by electron spin resonance spectroscopy. Cells that overexpress CYP2E1 can be protected from arachidonic acid toxicity damage by TEMPOL.

Ischemic acute kidney injury (iAKI) in diabetes mellitus is associated with a rapid deterioration of kidney function, more than in nondiabetic subjects. TVP1022, a non-MAO inhibitor S-isomer of rasagiline, possesses antioxidative and antiapoptotic activities. The current study examines the effects

Peroxisome proliferator-activated receptor (PPAR)-α deletion induces a profound decrease in MnSOD activity, leading to oxidative stress and left ventricular (LV) dysfunction. We tested the hypothesis that treatment of PPAR-α knockout (KO) mice with the SOD mimetic tempol prevents the heart
