In vitro
Rigosertib (ON-01910) is a non-ATP-competitive inhibitor to PLK1 with IC50 of 9 nM. It also exhibits inhibition against PLK2, PDGFR, Flt1, BCR-ABL, Fyn, Src, and CDK1, with IC50 of 18-260 nM. This compound 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, it 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. It 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, this compound (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, it (50 nM-0.5 μM) induces loss of viability and caspase 3/7 activation. In a recent study, Rigosertib induces apoptosis in chronic lymphocytic leukemia (CLL) cells without toxicity against T-cells or normal B-cells. It also abrogates the pro-survival effect of follicular dendritic cells on CLL cells and reduces SDF-1-induced migration of leukemic cells.
Kinase Assay
In vitro enzymtests voor PLK1
Recombinant PLK1 (10 ng) wordt geïncubeerd met verschillende concentraties Rigosertib (ON-01910) in een reactiemengsel van 15 µL (50 mM HEPES, 10 mM MgCl2, 1 mM EDTA, 2 mM Dithiothreitol, 0,01% NP-40 [pH 7.5]) gedurende 30 min bij kamertemperatuur. Kinase-reacties worden uitgevoerd gedurende 20 min bij 30 °C in een volume van 20 µL (15 µL enzym + deze verbinding, 2 µL 1 mM ATP), 2 µL γ32P-ATP (40 μCi) en 1 µL recombinant Cdc25C (100 ng) of caseïnesubstraten (1 μg). Reacties worden beëindigd door 2 min koken in 20 µL 2× Laemmli-buffer. Gefosforyleerde substraten worden gescheiden door 18% SDS-PAGE. De gels worden gedroogd en 3-10 min blootgesteld aan röntgenfilm.
In vivo
In mouse xenograft models of Bel-7402, MCF-7, and MIA-PaCa cells, Rigosertib (ON-01910) (250 mg/kg) markedly inhibits tumor growth. This compound (200 mg/kg) also shows inhibition on tumor growth in a mouse xenograft model of BT20 cells.
