CCT007093, a thienylidene cyclopentanone, is a potent PPM1D (WIP1) inhibitor with IC50 of 8.4 μM. The PPM1D gene is aberrantly amplified in a range of common cancers and encodes a protein phosphatase that is a potential therapeutic target. CCT007093 shows a potent inhibition of PPM1D in an in vitro assay when using the recombinant phospho-P38 as a substrate. In cellular assay, CCT007093 shows specificity for MCF-7 cells over HeLa cells. It reduces 40% viability of the cells after 2 days. It is found that the cell death induced by CCT007093 is dependent on P38 kinase activity. CCT007093 mimics the effect of PPM1D RNAi in activating P38 kinase.
ln Vitro |
The phosphorylation levels of mTOR at Ser2448, Ser2481, and Ser2159 are dramatically increased by CCT007093 (25 or 50 µM, 8 h). In transfected HEK293T cell line, the phosphorylation levels of p70S6K (Thr389) and S6 (Ser235/236) are also up-regulated [1]. CCT007093 exhibits selectivity for MCF-7 cells, causing a 40% reduction in viability after two days but having no discernible impact on HeLa cell growth[2]. In MCF-7 cells, which are sensitive to PPM1D inhibition, CCT007093 causes P38 phosphorylation four hours after exposure. In HeLa cells, which are comparatively resistant to PPM1D inhibition, P38 phosphorylation is not induced by CCT007093[2].

Mice undergoing major hepatectomy have a higher survival rate and more liver regeneration after receiving CCT007093 (6.4 mg/kg)[1].

Cell Assay |
Western Blot Analysis[1]
Cell Types: HEK293T cell line. Tested Concentrations: 25 or 50 µM. Incubation Duration: 8 h. Experimental Results: The phosphorylation levels of mTOR at Ser2448, Ser2481 and Ser2159 were all Dramatically increased[1]. The phosphorylation levels of p70S6K (Thr389) and S6 (Ser235/236) were also up-regulated[1]. |
Animal Protocol |
Animal/Disease Models: Wild-type mice[1].
Doses: 3.2 and 6.4 mg/kg. Route of Administration: Injected intraperitoneally 4 times (mice were sacrificed at 36 h post-PH). Experimental Results: Dramatically improved survival in mice following major hepatectomy (80% hepatectomy). The level of PCNA was also Dramatically increased in the liver of CCT007093-treated mice at 36h, 48h and 72h post-PH. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution 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 stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
Novel drug combinations sensitize breast cancer cells to paclitaxel. A. MDA-MB-231, MDA-MB-468, and MCF-7 breast cancer cell lines were seeded in six-well plates and treated with vehicle (control), < IC50 concentrations of the putative PPM1D inhibitor, CCT007093 (CCT); paclitaxel (tax); or a combination of both (CCT + tax). Cells were treated for 72 h, washed, trypsinized and counted. The percent of viable cells relative to control was plotted for each drug or combination. B. Same as A with < IC50 concentration the putative SP1-binding inhibitor, mithramycin (mith). Error bars represent standard deviation of triplicates from three independent experiments. * indicates P < 0.05, ** indicates P < 0.01. Breast Cancer Res . 2010;12(3):R41. td> |
Analysis of drug combinations on growth of breast cancer cells grown in 3D cultures. A. Cells were seeded on Matrigel in eight-well chamber slides as described in Materials and Methods. 3D cultures formed after two days and were treated every two to three days with single agents, vehicle (control), 1 nM paclitaxel (tax), 500 nM LY2109761 (LY), 10 μM CCT007093 (CCT), 25 nM mithramycin (mith) (upper panels) or a combination of drugs (lower panels). After 10 to 14 days, mammospheres were visualized using phase-contrast microscopy. Bar scale, 50 μm. B. To count cell numbers, the Matrigel was dissolved, mammospheres were collected, trypsinized and single cells were counted by trypan blue exclusion assay using a hemocytometer. The percent cell number relative to control was plotted for each drug or combination for the two cell lines. Error bars represent standard deviation from replicates from three independent experiments. Breast Cancer Res . 2010;12(3):R41. td> |
Drug combinations to enhance cell death of TNBC cell lines. A. Twenty-two triple-negative cell lines were each seeded in 96-well plates. The next day cells were treated with vehicle control or paclitaxel (0.3 to 30 nM). IC50 values for each cell line were generated based on the median-effect plot from three independent experiments. IC50 values represent the inhibitor concentration required for a 50% reduction in cell viability relative to vehicle-treated controls. Error bars represent standard deviation of four replicates from three independent experiments. B. Cell lines were seeded in 96-well plates and treated with single agents (IC50 values) or a combination of drugs (CCT007093 + paclitaxel or mithramycin + paclitaxel) of the IC50 concentrations of each drug (1:1 ratio) serial-diluted (IC50-IC25-IC12.5). Combination index (CI) values were calculated using the Chou-Talalay method with CalcuSyn software (Biosoft). CI values significantly > 1 are antagonistic, not significantly different than 1 are additive, and values < 1 are synergistic. Error bars represent standard deviation of quadruplicates from three independent experiments. Breast Cancer Res . 2010;12(3):R41. td> |
