| In Vitro | TAK-960 inhibits full-length PLK1 protein with IC50 of 0.8 nM, wich is 20-fold lower than the next lowest IC50 value (PLK2: 16.9 nM). TAK-960 (2-1000 nM) causes accumulation of G2-M cells in HT-29 cells. TAK-960 inhibits proliferation of multiple cancer cell lines, with mean EC50 values ranging from 8.4 to 46.9 nM, but not in nondividing normal cells[1]. TAK-960 (8 nM) leads to G2/M cell cycle arrest without significant cytotoxicity in HeLa cells. TAK-960 does not sensitize cancer cells to radiation when an insufficient amount of time is provided to induce mitotic arrest. The overexpression of a PLK1 mutant, PLK1-R136G&T210D, which is confirmed to cancel the TAK-960-mediated increase in the proportion of mitotic cells, abrogates the radiosensitizing effects of TAK-960[2]. |
| In Vivo | TAK-960 (7.5 mg/kg, p.o.) shows a significant increase in median survival compared with vehicle in MV4-11 human leukemia model. TAK-960 (10 mg/kg, p.o.) inhibits tumor growth in the MDR1-expressing K562ADR-bearing leukemia xenograft model[1]. TAK-960 (10 mg/kg) significantly suppresses tumor growth when combined with IR in tumor xenografts[2]. |
| Kinase Assay | The inhibitory activity of TAK-960 is assessed by the TR-FRET (fluorescence resonance energy transfer) assay, which measures the ATP-dependent phosphorylation of a biotinylated substrate peptide corresponding to residues 2,470 through 2,488 of the mTOR protein (Biotin-AGAGTVPESIHSFIGDGLV). A total of 288 kinases are screened for TAK-960 inhibition (1 μM) using HotSpot technology and IC50 values for the selected kinases are determined. |
| Cell Assay | Cells are seeded into 96-well plates at 3,000 to 30,000 cells per well in appropriate medium plus 10% fetal calf serum. After 24 hours, cells are treated with serial dilutions of TAK-960, and 72 hours later, the number of viable cells is assessed using the CellTiter-Glo Assay. Calculation of EC50 values and statistical analysis are done using GraphPad Prism software. |
| Animal Admin | The suspension of HeLa cells (2×106 in 100 μL PBS) or H1299 cells (3×106 in 100 μL PBS) is subcutaneously inoculated into the right hind legs of 8-week-old nude mice (BALB/c nu/nu mice). The indicated dose of TAK-960 is orally administered to tumor-bearing mice. In the radiation treatment, tumor xenografts are locally irradiated with the indicated dose of 137Cs γ-rays using a Gammacell 40 Exactor. |
