Description Praeruptorin B is an inhibitor of sterol regulatory element-binding proteins (SREBPs). It can also significantly up-regulate CYP3A4 expression and activity via the PXR-mediated pathway.
In vitro Praeruptorin B inhibits the SREBPs activity and decreases intracellular lipid levels. Praeruptorin B powerfully decreases SRE-luciferase activity in a dose-dependent manner. Praeruptorin B shows negligible cytotoxicity, even at the higher concentration. Praeruptorin B also significantly down-regulates the expression of SREBP-1c and SREBP-2 [1]. Praeruptorin B also exhibits significant inhibition on the activity of UGT1A9 [2].
In vivo The mice treated with Praeruptorin B (50 mg/kg) are significantly lighter than the vehicle-treated mice, although they are still heavier than the chow diet-fed mice. More importantly, the fat/lean and fat/body-weight ratios are obviously dropped at the same dosage of Praeruptorin B treated mice. It is also showed that the serum TC and TG levels of Praeruptorin B treated mice are significantly lower than those of the HFD-fed mice. Praeruptorin B increases HDL-c and decreases LDL-c similar to lovastatin. In addition, compared with vehicle-treated mice, Praeruptorin B significantly lowers the level of TC and TG in the liver, comparable to lovastatin. The elevated fasting blood glucose and insulin in HFD-fed mice are significantly reduced by Praeruptorin B [1].

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

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.
