Storage & Solubility Information
Description (S)-crizotinib (ent-crizotinib) (IC50 of 72 nM), an effective MTH1 (NUDT1) inhibitor, is the (S)-enantiomer of crizotinib.
Targets&IC50 MTH1:72 nM
In vitro In the SW480 colorectal cancer model, daily oral administration of 50mg/kg (S)-Crizotinib effectively inhibits tumor growth.
In vivo (S)-crizotinib activates DNA repair mechanisms in human colorectal cancer cells by inhibiting MTH1, thereby disrupting nucleotide pool homeostasis and further inducing an increase in DNA single-strand breaks.
Kinase Assay MTH1 catalytic assay: Half-maximal inhibitory concentrations (IC50) are determined using a luminescence-based assay with some minor modifications. Briefly, serial dilutions of compounds are dissolved in assay buffer (100?mM Tris-acetate pH?7.5, 40?mM NaCl and 10?mM Mg(OAc)2 containing 0.005% Tween-20 and 2?mM dithiothreitol (DTT). Upon addition of MTH1 recombinant protein (final concentration 2?nM), plates are incubated on a plate shaker for 15?min at room temperature. After addition of the substrate dGTP (final concentration 100?μM), 8-oxo-dGTP (final concentration 13.2?μM), or 2-OH-dATP (final concentration 8.3?μM) the generation of pyrophosphate (PPi) as a result of nucleotide triphosphate hydrolysis by MTH1 is monitored over a time course of 15?min using the PPi Light Inorganic Pyrophosphate Assay kit. IC50 values are determined by fitting a dose-response curve to the data points using nonlinear regression analysis using the GraphPad Prism software.
Cell Research One day before treatment, cells are seeded per well in six-well plates and incubated for 24 h. The next day DMSO (equal to highest amount of compound dilution, maximum 0.2%) or compounds in increasing concentrations were added and cells incubated at 37 °C, 5% CO2, for 7-10 days. After washing with PBS, cells are fixed with ice-cold methanol, stained with crystal violet solution (0.5% in 25% methanol) and left to dry overnight. For quantification of results, ultraviolet absorbance of crystal violet is determined at 595 nm following solubilisation by 70% ethanol. Data are analysed using nonlinear regression analysis using the GraphPad Prism software. (Only for Reference)

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
