Overview

TEMPOL is a superoxide dismutase mimetic that belongs to a class of non-thiol-containing radiation protectors, and has the ability to permeate the membrane. In the presence of TEMPOL, cerebral vessel remodeling is blocked and collagen IV mRNA expression levels are elevated in normotensive and hypertensive rat studies. TEMPOL has been shown to restore the oxidative stress and cardiac dysfunction induced by TNF-α and in PC-12 cells has revealed neuroprotective effects. Additionally, it has shown to decrease blood pressure and sympathetic nerve activity in DOCA-salt rat studies.


product description:

4-Hydroxy-TEMPO is a 4-substituted 2,2,6,6-tetramethylpiperidyl-1-oxy (TEMPO) derivative. It is a low-molecular weight compound and has been proposed as superoxide dismutase mimic.

Note
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
