Description AT9283 is an effective multi-targeted inhibitor of JAK2(IC50=1.2 nM) and JAK3(IC50=1.1 nM), Aurora A, Aurora B and Abl(T315I).
Targets&IC50 Abl1 (T315I) :ic50 4nM,   Aurora A :ic50 ~3.0nM,   Aurora B :ic50 ~3.0nM,   JAK2 :ic50 1.2nM,   JAK3 :ic50 1.1nM,  
Kinase Assay Aurora A and Aurora B Kinase Assays: Assays for Aurora A and B are performed in a DELFIA format. Aurora A enzyme is incubated with AT9283 and 3 μM cross-tide substrate (biotin-CGPKGPGRRGRRRTSSFAEG) in 10 mM MOPS, pH 7, 0.1 mg/mL BSA, 0.001% Brij-35, 0.5% glycerol, 0.2 mM EDTA, 10 mM MgCl2, 0.01% β-mercaptoethanol, 15 μM ATP, and 2.5% DMSO. Aurora B enzyme is incubated with AT9283, 3 μM of the above substrate in 25 mM Tris, pH 8.5, 5 mM MgCl2, 0.1 mg/mL BSA, 0.025% Tween-20, 1 mM DTT, 15 μM ATP, and 2.5% DMSO. Reactions are allowed to proceed for 60 minutes and 45-90 minutes for Aurora A and Aurora B, respectively, before quenching with EDTA. The reaction mixtures are then transferred to a neutravidin-coated plate, and phosphorylated peptide is quantified by means of a phospho-specific antibody and a europium labeled secondary antibody using time-resolved fluorescence (excitation, 337 nm; emission, 620 nm). IC50 values for the control compounds are 92 nM (Aurora A assay) and 17 nM (Aurora B).
Cell Research
HCT 116 cells are cultured in DMEM + 10% FBS + GLUTAMAX I. Black 96-well flat-bottomed (clear) tissue culture treated plates are seeded in 200 μL of medium and incubated for approximately 16 hours at 37°C in a humidified atmosphere of 5% CO2 in air. Cells are treated with test compound at nine different concentrations (spanning 1 nM to 10 μM, plus DMSO vehicle control) and then incubated for 72 hours. Polyploidy morphological observations of the cells are then noted. The concentration of AT9283 required to produce a distinct polyploid phenotype is reported. Cells are seeded at a concentration of 75−100 cells/mL relevant culture media onto 6- or 24-well tissue culture plates and allowed to recover for 16 hours. Test compound (11 concentrations spanning 0.1 nM to 10 μM) or vehicle control (DMSO) is added to duplicate wells to give a final DMSO concentration of 0.1%. Following compound addition, colonies are allowed to grow between 10 and 14 days for optimum discrete colony counting. Colonies are fixed in 2 mL of Carnoys fixative (25% acetic acid, 75% MeOH) and stained in 2 mL of 0.4% w/v crystal violet. The numbers of colonies in each well is counted. IC50 values are calculated by sigmoidal dose-response (variable slope) IC50 curves using Prism Graphpad software. (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
