NCIt synonyms : Polo-like kinase 1 Inhibitor ON 01910.Na; Polo-like kinase 1 Inhibitor ON 01910 Na;
NCIt related terms : ON 01910.Na;
NCIt definition : The sodium salt form of rigosertib, a synthetic benzyl styryl sulfone analogue and
Ras mimetic, with potential antineoplastic activity. Upon administration, rigosertib
targets and binds to Ras-binding domain (RBD) found in many Ras effector proteins,
including Raf kinase and phosphatidylinositol 3-kinase (PI3K). This prevents Ras from
binding to its targets and inhibits Ras-mediated signaling pathways, including Ras/Raf/Erk,
Ras/CRAF/polo-like kinase1 (Plk1), and Ras/ PI3K/Akt signaling pathways. This induces
cell cycle arrest and apoptosis and inhibits proliferation in a variety of susceptible
tumor cells.;
Alternative definition : NCI-GLOSS: A substance being studied in the treatment of cancer. It blocks certain
proteins that are needed for cell growth and may kill cancer cells. ON 01910.Na is
a type of protein kinase inhibitor and a type of benzyl styryl sulfone analog.;
