In Vitro

NMS-1286937 is a potent, selective and orally available PLK1 inhibitor, with IC50 of 2 nM. NMS-1286937 also shows inhibitory activities against FLT3, MELK, and CK2, with IC50s of 510, 744, and 826 nM, respectively[1]. NMS-P937 possesses a pure ATP competitive mechanism with a reversible dissociation and no time dependency. NMS-P937 (10 μM) is selective with a marginal activity of 48% and 40% inhibition on PLK2 and PLK3, respectively. NMS-P937 shows antiproliferative activity against a panel of 137 cell lines, with IC50 values of below 100 nM for 60 of 137 cell lines and higher than 1 μM for only 9 of 137 cell lines[2]. NMS-P937 shows cytotoxic activity against AmL-NS8 cells with IC50 of 36 nM[3].

In Vivo

NMS-1286937 (45 mg/kg, i.v.) shows a good tumor growth inhibition with acceptable and reversible body weight loss in CD1 nu/nu mice xenografted with human HCT116 colon adenocarcinoma cells. NMS-1286937 (60 mg/kg, p.o.) also inhibits the growth of tumor on HCT116 xenograft model[1]. NMS-P937 (45 mg/kg, i.v.or 60 mg/kg, p.o) inhibits tumor growth to a comparable degree (TGI, 83% and 79% intravenously and orally, respectively) in HCT116-bearing mice. The combination of NMS-P937 (120 mg/kg given for 4 cycles of 2 consecutive days with 10-day rest) and cytarabine (75 mg/kg for 4 cycles of 5 consecutive days with 7-day rest) in the disseminated leukemia model AmL-PS is well tolerated and clearly showed increased mice survival[2]. NMS-P937 (60 mg/kg bid os per day over 2 days with a 5 day rest) shows good efficacy compared to standard therapies, with a significant increase in median survival time (MST) in the established disease setting[3].

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 mg/mL (3.76 mM); Clear solution

    This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 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 mg/mL (3.76 mM); Clear solution

    This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 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.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.

Kinase Assay
[1]

The inhibitory activity of putative kinase inhibitors and the potency of selected compounds are determined using a trans-phosphorylation assay. Specific peptide or protein substrates are trans-phosphorylated by their specific serine-threonine or tyrosine kinase, in the presence of ATP traced with 33P-γ-ATP, at optimized buffer and cofactors conditions. At the end of the phosphorylation reaction, more than 98% unlabeled ATP and radioactive ATP is captured by adding an excess of the ion exchange dowex resin; the resin then settles down to the bottom of the reaction plate by gravity. Supernatant, containing the phosphorylated substrate, is subsequently withdrawn and transferred into a counting plate, followed by evaluation by b-counting. Inhibitory potency evaluation for all the tested kinases is performed at 25°C using a 60 min end-point assay where the concentrations of ATP and substrates are kept equal to 2 × αKm and saturated (>5 × αKm), respectively.

Cell Assay
[2]

Cells are seeded into 96- or 384-well plates at densities ranging from 10,000 to 30,000/cm2 for adherent and 100,000/mL for nonadherent cells in appropriate medium supplemented with 10% fetal calf serum. After 24 hours, cells are treated in duplicate with serial dilutions of NMS-P937, and 72 hours later, the viable cell number is assessed by the CellTiter-Glo Assay. IC50 values are calculated with a sigmoidal fitting algorithm. Experiments are carried out independently at least twice.

Animal Administration
[2]

For carcinoma xenograft studies, 5- to 6-week-old female Hsd, athymic nu/nu mice (average weight, 20-22 g), are used. HCT116, HT29, Colo205 colorectal, and A2780 ovarian human carcinoma cell lines are inoculated subcutaneously. Mice bearing a palpable tumor (100-200 mm3) are treated with vehicle or NMS-P937 following doses and schedules starting from the day after randomization. Tumor dimensions are measured regularly with Vernier calipers, and tumor growth inhibition (TGI) is calculated. Toxicity is evaluated on the basis of body weight reduction. For leukemia studies, 5- to 6-week-old female severe combined immunodeficient mice (SCID; average weight, 20-22 g) are used. The AmL cell line HL-60 (5×106 cells) is injected subcutaneously and treatments initiated when tumor size reaches 200 to 250 mm3. Tumor dimensions and TGI are assessed. For disseminated models, 5×106 AmL primary cells (AmL-PS) are injected intravenously and treatments start after 2 days. Mice are monitored daily for clinical signs of disease, and the median survival time is determined for each group.

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.
