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.

Mechanism of Action

Features
MTH1 (NUDT1)- selective inhibitor.
Targets/IC50/Ki
NUDIX1
MTH1
(Cell-free assay)
72 nM
In vitro
(S)-crizotinib disrupts nucleotide pool homeostasis via MTH1 inhibition, induces an increase in DNA single-strand breaks, and activates DNA repair in human colon carcinoma cells.
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.
In vivo
(S)-Crizotinib (50 mg/kg, orally, daily) impairs tumor growth in an SW480 colon carcinoma xenograft model.

Frequently Asked Questions

Question 1:
Could you tell me whether this product represents the pure R-form of it, or is the the racemic Crizotinib, so a mixture of the S- and the R-form?

Answer:
Our S1068 Crizotinib is R enantiomer, and S7505 is S enantiomer. Normally, it refers to the R enantiomer.
