Storage & Solubility Information
Description Nedisertib (M3814) is a specific inhibitor of DNA-dependent Protein Kinase (DNA-PK, IC50: <3 nM).
Targets&IC50 DNA-PK:<3 nM
In vitro Nedisertib is a DNA-PK inhibitor, with an IC50 of <3 nM for DNA-PK and <0.5 μΜ for cellular pDNA-PK [2].
In vivo In combination with IR, Nedisertib shows efficacy in all of the 6 mouse models of human cancer. Nedisertib, alone or in combination with IR, does not induce significant weight loss or visual signs of toxicity in the mice in any study. In all models, a dose of 2 Gy administered daily for 1 week in combination with Nedisertib induces statically significant tumor growth inhibition to compare to IR alone [1].
Animal Research The efficacy of Nedisertib in combination with IR is evaluated in 6 human xenograft models (NCI-H460, A549, HCT116, FaDu, Capan-1, BxPC3) in mice representing 4 different cancer types (colon, head and neck, lung, and pancreas). Tumor cells are injected s.c. into nude mice, and treatment starts when palpable tumors are established (~100 to 200 mm^3 ). Nedisertib is given orally at different doses (25 to 300 mg/kg) 10 min prior to IR. IR is applied using a radiation therapy device for small rodents calibrated to deliver 2 Gy. Autophosphorylation of DNA-PK (serine2056) in FaDu tumor lysates is measured by immunoassay to assess pharmacological inhibition by Nedisertib [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


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.
