(S)-Crizotinib is a potent and selective MTH1 (mutT homologue) inhibitor with an IC50 of 330 nM. (S)-Crizotinib disrupts nucleotide pool homeostasis via MTH1 inhibition, induces an increase in DNA single strand breaks, activates DNA repair in human colon carcinoma cells, and effectively suppresses tumour growth in animal models.

Description

(S)-Crizotinib is a potent and selective MTH1 (mutT homologue) inhibitor with an IC50 of 330 nM. (S)-Crizotinib disrupts nucleotide pool homeostasis via MTH1 inhibition, induces an increase in DNA single strand breaks, activates DNA repair in human colon carcinoma cells, and effectively suppresses tumour growth in animal models[1].

IC50 & Target

IC50: 330 nM (MTH1)[1]

In Vitro

(S)-crizotinib (0.625-80 μM; 24 hours) decreases the viability of NCI-H460, H1975 and A549 cells with IC50 values of 14.29, 16.54 and 11.25 μM, respectively[2].
(S)-crizotinib (10-30 μM; 24 hours) induces NCI-H460, H1975 and A549 cells apoptosis[2].
(S)-crizotinib (10-30 μM; 24 hours) decreases Bcl-2: Bax ratio. (S)-crizotinib decreases B cell lymphoma 2 (Bcl-2), and Bcl-2 associated protein x (Bax) is either unaltered (H460 cells) or shows an increase (H1975 cells)[2].
(S)-Crizotinib induces apoptosis in human non-small cell lung cancer (NSCLC) cells by activating ROS-dependent ER stress apoptotic pathway independent of mutT homologue (MTH1)[2].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 1.25 mg/mL (2.78 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 1.25 mg/mL (2.78 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
