In vitro

Rigosertib is non-ATP-competitive inhibitor to PLK1 with IC50 of 9 nM. Rigosertib also exhibits inhibition against PLK2, PDGFR, Flt1, BCR-ABL, Fyn, Src, and CDK1, with IC50 of 18-260 nM. Rigosertib shows cell killing activity against 94 different tumor cell lines with IC50 of 50-250 nM, including BT27, MCF-7, DU145, PC3, U87, A549, H187, RF1, HCT15, SW480, and KB cells. While in normal cells, such as HFL, PrEC, HMEC, and HUVEC, Rigosertib has little or no effect unless its concentration is greater than 5-10 μM. In HeLa cells, Rigosertib (100-250 nM) induces spindle abnormalities and apoptosis. [1] Rigosertib also inhibits several multidrug resistant tumor cell lines, including MES-SA, MES-SA/DX5a, CEM, and CEM/C2a, with IC50 of 50-100 nM. In DU145 cells, Rigosertib (0.25-5 μM) blocks cell cycle progression in G2/M phase, results in an accumulation of cells containing subG1 content of DNA, and activates apoptotic pathways. In A549 cells, Rigosertib (50 nM-0.5 μM) induces loss of viability and caspase 3/7 activation. [2] In a recent study, Rigosertib induces apoptosis in chronic lymphocytic leukemia (CLL) cells without toxicity against T-cells or normal B-cells. Rigosertib also abrogates the pro-survival effect of follicular dendritic cells on CLL cells and reduces SDF-1-induced migration of leukemic cells. [3]

In vivo In mouse xenograft models of Bel-7402, MCF-7, and MIA-PaCa cells, Rigosertib (250 mg/kg) markedly inhibits tumor growth. [1] Rigosertib (200 mg/kg) shows inhibition on tumor growth in a mouse xengraft model of BT20 cells. [2]

Protocol

Kinase Assay:[1]
- Collapse

In vitro enzyme assays for PLK1:

Recombinant PLK1 (10 ng) is incubated with different concentrations of Rigosertib in a 15 µL reaction mixture (50 mM HEPES, 10 mM MgCl2, 1 mM EDTA, 2 mM Dithiothreitol, 0.01% NP-40 [pH 7.5]) for 30 min at room temperature. Kinase reactions are performed for 20 min at 30 °C in a volume of 20 µL (15 µL enzyme + inhibitor, 2 µL 1 mM ATP), 2 µL of γ32P-ATP (40 μCi), and 1 µL of recombinant Cdc25C (100 ng) or casein (1 μg) substrates. Reactions are terminated by boiling for 2 min in 20 µL of 2× Laemmli buffer. Phosphorylated substrates are separated by 18% SDS-PAGE. The gels are dried and exposed to X-ray film for 3-10 min.

  • Cell lines: A number of tumor cell lines, including BT20, MCF-7, DU145, PC3, U87, A549, H187, RF1, HCT15, HeLa, and Raji cells
  • Concentrations: 1 nM - 10 μM, dissolved in DMSO as stock solution.
  • Incubation Time: 96 hours
  • Method: Cells are grown in either DMEM or RPMI supplemented with 10% fetal bovine serum and 1 unit/mL penicillin-streptomycin solution. Tumor cells are plated into six-well dishes at a density of 1 × 105cells/mL/well, and Rigosertib is added 24 hours later at various concentrations. Cell counts are determined from duplicate wells after 96-hour of treatment. The total number of viable cells is determined by trypan blue exclusio
