4-Hydroxy-TEMPO

产品介绍

Tempol 是一种超氧化物歧化酶 (SOD) 类似物，可有效中和活性氧 (ROS)。

生物活性

Tempol is a general superoxide dismutase (SOD)-mimetic drug that efficiently neutralizesreactive oxygen species(ROS).

IC₅₀& Target

ROS^[1]

体外研究
(In Vitro)

Tempol significantly attenuates H₂O₂-mediated decrease in mitochondrial respiration and increase in LDH release from rat PT cells, indicating a reduction in cell injury and death. The beneficial actions of Tempol are similar to those obtained using the Fe²⁺chelator DEF. However, coadministration of DEF and Tempol does not produce any additional beneficial actions against renal ischemia/reperfusion injury or against oxidative stress-mediated PT cell injury/death^[2].

体内研究
(In Vivo)

SOD-mimetic Tempol is able to mimic resveratrol’s effects on heart function. Tempol is administered daily by gavage. Mice treated with Met or Tmp had decreased PR and QTc intervals and increased heart rates compared to peroral vehicle (VEH). These results are similar to that obtained by treatment with RSV. Pre- and post-treatment profiles of individual mice are illustrated^[1]. Tempol, a membrane-permeable radical scavenger, reduces oxidant stress-mediated renal dysfunction and injury in the rat. Tempol significantly reduces the increase in urea, creatinine, γGT, AST, NAG, and FE_Naproduced by renal ischemia/reperfusion, suggesting an improvement in both renal function and injury. Tempol also significantly reduces kidney MPO activity and MDA levels, indicating a reduction in PMN infiltration and lipid peroxidation, respectively. Tempol reduces the histologic evidence of renal damage associated with ischemia/reperfusion and caused a substantial reduction in the staining for nitrotyrosine and PARS, suggesting reduced nitrosative and oxidative stress^[2].
