Description

CFI-400945 fumarate is a potent, selective and orally bioavailable PLK4 inhibitor with a Ki and an IC50 of 0.26 nM and 2.8 nM, respectively.

IC50 & Target

Ki: 0.26 nM (PLK4)[1]
IC50: 2.8 nM (PLK4)[1]

In Vitro

CFI-400945 (compound 48) shows potent inhibitory activities against a panel of kinases, including PLK4, TRKA, TRKB, AURKA, AURKB/INCENP, and TIE2/TEK, with IC50s of 2.8, 6, 9, 140, 98, 22 nM, and EC50s of 12, 84, 88, 510, 102, 117 nM, respectively. CFI-400945 exhibits growth inhibition effects on breast, lung, ovarian and colon cancer cells. The IC50s (in μM) are as follows: SKBr-3 (5.3), Cal-51 (0.26), BT-20 (0.058), A549 (0.005), OVCAR-3 (0.018), SW620 (0.38), Colo-205 (0.017), and HCT116+/+ (0.004) [1]. CFI-400945 inhibits autophosphorylation of PLK4 at serine 305 with an EC50 value of 12.3 nM in cells overexpressing PLK4. Cancer cells treated with CFI-400945 exhibit effects consistent with PLK4 kinase inhibition, including dysregulated centriole duplication, mitotic defects, and cell death[2].

In Vivo

Oral administration of CFI-400945 (3.0, 9.4 mg/kg) to mice bearing human cancer xenografts results in the significant inhibition of tumor growth at doses that are well tolerated. Increased antitumor activity is observed in PTEN-deficient compared to PTEN wild-type cancer xenografts. The maximum tolerated dose for once-daily administration of CFI-400945 is estimated to be 7.5-9.5 mg/kg[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: ≥ 2.5 mg/mL (3.84 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (3.84 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

Purity & Documentation

Purity: 99.44%

Kinase Assay
[1]

Active PLK4 is purified and used to measure PLK4 activity, using an indirect ELISA detection system. PLK1, PLK2, PLK3, AURKA, and AUKB/INCENP compound inhibition are determined using FRET-based homogeneous assay kits from Invitrogen. The assays are performed with ATP concentrations of 25, 60, and 80 μM, respectively, for PLK1, PLK2, and PLK3 and ATP concentrations of 20 and 128 μM, respectively, for AURKA and AURKB/INCENP[1].

Animal Administration
[2]

Mice: To treat an established tumor, CFI-400945 and the vehicle (water) are administered by oral gavage (2.5-20 mg/kg), and 5-FU and carboplatin are administered by intraperitoneal injection to mice as described in the text. Animal weights are monitored daily, and tumor volume is measured three times per week[2].

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.
