Storage & Solubility Information
Description PDM 2 is a potent and selective aryl hydrocarbon receptor (AhR) antagonist.
Targets&IC50 AhR:1.2±0.4 nM(Ki)
In vitro In a previous screening study, it was found that the replacement of resveratrol hydroxyls by the same substituent produced compounds with the following order of affinity: OH (resveratrol) , OMe < F < CF3 < Cl (PDM 2). PDM 2 exhibited a Ki of 1.25 for AhR and no affinity for ER, indicating that replacement of hydroxyl with chloride could abolish binding on ER and dramatically increase the affinity for AhR. Moreover, among its analogs PDM 2 was the most potent AhR antagonists in this series, being 10-fold more efficient than resveratrol. PDM 2, devoid of measurable affinity for ER, did not display any effect on ER-driven transcription. Therefore, PDM 2 was considered as a selective AhR modulator with regard to ER. In addition, its trimethoxylated derivatives and 3,5-methoxy derivatives were able to induce cytotoxicity at doses lower than 100 nM, which was consistent with previous data. 3,5-Methoxy derivatives, however, only showed cytotoxicity at concentrations higher than 10 μM [1].

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.
