Solubility | DMSO: 50 mg/mL mother liquor preservation: sub-package and freeze storage to avoid repeated freezing and thawing;-20 ℃,1 month;-80 ℃,6 months (after dilution, the solution temperature is low and storage may precipitate, try to use it now) Cell experiment: Dissolve with DMSO first: dilute with culture medium then, and the dilution process is recommended to be carried out in stages to avoid too fast concentration change leading to compound precipitation. If the compound is precipitated during the dilution process, it can be redissolved by ultrasound. During dilution, ensure that the final concentration of DMSO in the working fluid should be below 0.1% as far as possible, and the maximum should not exceed 0.5%, and set up a DMSO control group with corresponding concentration. Animal experiment: Dissolve with DMSO first: dilute with water or normal saline, etc. The dilution process is recommended to be carried out in sections to avoid excessive concentration changes leading to compound pr |

Use | Rigosertib (ON-01910 sodium salt) is a synthetic benzyl styryl sulfone analogue with potential antineoplastic activity. Polo-like kinase 1 inhibitor ON 01910.Na inhibits polo-like kinase1 (Plk1), inducing selective G2/M arrest followed by apoptosis in a variety of tumor cells while causing reversible cell arrest at the G1 and G2 stage without apoptosis in normal cells. This agent may exhibit synergistic antitumor activity in combination with other chemotherapeutic agents. Plk1, named after the polo gene of Drosophila melanogaster, is a serine/threonine protein kinase involved in regulating mitotic spindle function in a non-ATP competitive manner. Note: this product is supplied as sodium salt. |
Target | PLK1 |
In vitro study | Rigosertib is a non-ATP competitive inhibitor of PLK1 with an IC50 of 9 nM. Rigosertib also inhibited PLK2,PDGFR,Flt1,BCR-ABL,Fyn,Src and CDK1 with an IC50 of 18-260 nM. Rigosertib has Cell Death activity, acting on 94 different tumor cell lines, IC50 is 50-250 nM, including BT27,MCF-7,DU145,PC3,U87,A549,H187,RF1,HCT15,SW480, and KB cells. Rigosertib has no effect on normal cells, such as HFL, Proc, HMEC, and HUVEC, unless the concentration of action is higher than 5-10 μm. 100-250 nM Rigosertib acts on HeLa cells to induce spindle variation and apoptosis. Rigosertib also inhibits a number of multidrug-resistant tumor cell lines, including MES-SA, MES-SA/DX5a, CEM, and CEM/C2a, with an IC50 of 50-nM. 0.25-5 µm Rigosertib acts on DU145 cells, inhibits the cell cycle, stops the cells in G2/M phase, and activates the apoptotic pathway. 50 nM-0.5 µm Rigosertib acts on A549 cells, inducing loss of viability and caspase 3/7 activation. Recent studies have shown that Rigosertib acts on chronic lymphocytic leukemia (CLL) cells, inducing apoptosis, and has no toxicity on T cells or normal B cells. Rigosertib chronic lymphocytic leukemia (CLL) cells also inhibit the pro-survival effect of follicular dendritic cells, acting on leukemia cells, reducing SDF-1 induced migration. |
In vivo study | Rigosertib at a dose of 250 mg/kg significantly inhibited tumor growth in murine xenograft tumor models carrying Bel-7402,MCF-7, and MIA-PaCa cells. Rigosertib also inhibited tumor growth at a dose of 200 mg/kg in a murine transplanted tumor model carrying BT20 cells. |
