Protocol (from reference)

Kinase Assay:[1]
  • In-vitro inhibitory enzyme kinetic assays:

    The assays are carried out in triplicate using the ATP/NADH coupled assay system in a 96-well format. The final reaction mixture contains 0.5 mg/mL Bovine Serum Albumin (BSA), 2 mM MnCl2, 1 mM phospho(enol) pyruvic acid (PEP), 1 mM TCEP, 0.1 M Hepes 7.4, 2.5 mM poly-[Glu4Tyr1] peptide, 1/50 of the final reaction mixture volume of pyruvate kinase/lactic dehydrogenase enzymes from rabbit muscle, 0.5 mM NADH, 0.5 μM EGFR kinase, 100 μM ATP and varied amount of WZ3146. WZ3146 and ATP are mixed and made separate stock from the mixture with all other ingredients and added last to the latter to start the reaction. Steady state initial velocity data are drawn from the slopes of the A340 curves.

Cell Research:[1]
  • Cell lines: NSCLC and Ba/F3 cells
  • Concentrations: 0-10 μM
  • Incubation Time: 72 hours
  • Method: Growth and inhibition of growth is assessed by MTS assay. NSCLC or Ba/F3 cells are exposed to treatment for 72 hours and the number of cells used per experiment is determined empirically. All experimental points are set up in six to twelve wells and all experiments are repeated at least three times. The data is graphically displayed using GraphPad Prism version 5.0 for Windows. The curves are fitted using a non-linear regression model with a sigmoidal dose response.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
