Biological Description
Chemical Properties
Storage & Solubility Information
Description Tempol is a superoxide scavenger. It has anti-inflammatory, neuroprotective and analgesic effects.
In vitro Tempol (4-Hydroxy-TEMPO) is a stable, cell-permeable nitroxide that acts as a free radical scavenger and nitric oxide spin trap. Tempol Exhibits radio-protective and anti-proliferative properties. Tempol inhibits oxygen-dependent radiation-induced damage. [1] Tempol induces oxidative stress and enhances the levels of p21WAF1 in HL-60 cells in a dose-dependent manner. [2]
In vivo Tempol reduces oxidant stress-mediated renal dysfunction and injury in the rat. [3] Tempol prevents cerebral vessel remodeling in hypertensive rats. [4] Tempol lowers blood pressure and sympathetic nerve activity but not vascular O2- in DOCA-salt rats. [5] Tempol restores mitochondrial and cardiac functions in TNFα-induced oxidative stress and reduces cardiac hypertrophy in chronic hypoxic rats. [6]
Cell Research The antiproliferative effect of Tempol is assessed by the MTT assay after 96 h exposure of the cells to the drug. Briefly, 100,000 cells/mL are seeded onto 96-well plates and allowed to grow for 24 h before treatment with different concentrations of Tempol (0.05–1.6 mM).(Only for Reference)

Molecular Weight Calculator

Molarity Calculator allows you to calculate the

  • Mass of a compound required to prepare a solution of known volume and concentration
  • Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Concentration of a solution resulting from a known mass of compound in a specific volume
See Example

An example of a molarity calculation using the molarity calculator
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
Press calculate
The answer of 19.713 mg appears in the Mass box


Calculator the dilution required to prepare a stock solution

Calculate the dilution required to prepare a stock solution
The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
Press calculate
The answer of 100 microliter (0.1 ml) appears in the Volume (start) box

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed n the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
