Rigosertib sodium

Research use only, not for human use.

Rigosertib sodium (ON 01910.Na) is a potent, non-ATP-competitive PLK1 inhibitor (IC50=9-10 nM).

Rigosertib sodium (ON 01910.Na) is a potent, non-ATP-competitive PLK1 inhibitor (IC50=9-10 nM), selectively induces mitotic G2/M arrest and apoptosis in cancer cells; also exhibits inhibitory activity against PDGFR, Abl, and Flt-1, at higher concentrations, inhibits CDK1, Plk2, Src, and Fyn; demonstrates in vitro cytotoxicity against DU145 and K562 cells with IC50 of 100 and 15 nM; potently inhibits tumor growth in a variety of xenograft nude mouse models, does not exhibit hematotoxicity, liver damage, or neurotoxicity shows strong synergy with several chemotherapeutic agents.Blood Cancer Phase 3 Clinical(In Vitro):Rigosertib is non-ATP-competitive inhibitor of PLK1 with IC50 of 9 nM. Rigosertib also exhibits inhibition of 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. 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. Rigosertib sodium (2 μM) induces apoptosis in chronic lymphocytic leukemia (CLL) cells without toxicity against T-cells or normal B-cells. Rigosertib sodium (2 μM) also abrogates the pro-survival effect of follicular dendritic cells on CLL cells and reduces SDF-1-induced migration of leukemic cells.(In Vivo):Rigosertib (250 mg/kg, i.p.) markedly inhibits tumor growth in mouse xenograft models of Bel-7402, MCF-7, and MIA-PaCa cells. Rigosertib (200 mg/kg, i.p.) shows inhibition on tumor growth in a mouse xengraft model of BT20 cells.
