Biological Activity
ROS[1]
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].

Effect of MitoTEMPO and Tempol (5-40 μM) on cellular ROS and mitochondrial ROS levels in erastin-treated cells (fluorescence microscopy, scale bar = 100 μm). Cells were treated with 2.5 μM erastin with or without other drugs as indicated. The staining for cellular ROS, mitochondrial lipid-ROS, and mitochondrial ROS was carried out at 8, 10 and 12 h, respectively, following erastin exposure. The results showed that at a concentration of 40 μM, Tempol effectively reduced erastin-induced accumulation of intracellular ROS, mitochondrial ROS, and lipid ROS.

Protocol
To investigate the effect of Tempol, DEF, and DEF coadministered with Tempol on H2O2-mediated cell injury and death, confluent cultures of PT cells are preincubated (10 min at 37°C) with Tempol (0.03 to 10 mM), DEF (0.03 to 10 mM), or DEF (3 mM) in combination with Tempol (3 mM). The ranges of concentrations of Tempol and DEF are based on those previously shown in this laboratory to reduce on H2O2-mediated cell injury and death in (1) cultured rat cardiac myoblasts (Tempol) and (2) primary cultures of rat PT cells (DEF ). PT cell cultures are then incubated with H2O2 (1 mM) for four hours, after which cellular injury and death are assessed. Upon completion of incubations, cellular injury and death are assessed using the spectrophotometric assays described later in this article[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Mice[1]
Female or male BALB/c mice (5-7 weeks of age) are used. Mice are infected intraperitoneally (i.p.) with 102 blood trypomastigote forms of the type I Colombian strain of T. cruzi. Treatments are performed daily for 30 days from the establishment of CCC (60 dpi) by i.p. injection of 15 mg/kg trans-resveratrol (10% ethanol/PBS), vehicle (10% ethanol/PBS), 5 mg/Kg EX527 (0.1% DMSO), or peroral administration of 40 mg/Kg Resveratrol (10%ethanol-PBS), 500 mg/kg Metformin (dissolved in water), 100 mg/kg Tempol (dissolved in water), Benznidazole (25 mg/Kg, dissolved in water) and vehicle (water or 10%ethanol-PBS).
Rats[2]
83 male Wistar rats weighing 230 to 320 g are used.Upon completion of surgical procedures, the animals are randomly allocated to the eight groups. At one minute before commencement of reperfusion, animals received a bolus injection of either vehicle (saline, 4 mL/kg, IV), Tempol (30 mg/kg in saline, IV), DEF (40 mg/kg in saline, IV), or DEF (40 mg/kg in saline, IV) in combination with Tempol (30 mg/kg in saline, IV). The corresponding groups then received a continuous infusion of one of the following throughout the reperfusion period: vehicle (saline, 4 mL/kg/h, IV), Tempol (30 mg/kg/h in saline, IV), DEF (40 mg/kg/h in saline, IV), or Tempol and DEF in combination (30 and 40 mg/kg/h, respectively, in saline, IV). To elucidate the effects of Tempol or DEF on cardiovascular hemodynamics and organ function in sham-operated rats, respective groups of animals received the treatments described previously in this article and as outlined. The concentration of Tempol administered in vivo is based on those previously demonstrated by us to provide significant protection against myocardial ischemia/reperfusion injury in an in vivo rat model. Similarly, the concentration of DEF used is identical to that which we have previously used to provide significant protection against hepatic ischemia/reperfusion injury in in vivo rat and rabbit models.
