Rigosertib
DCTPepD ID DCTPepD0083
Active Ingredients Rigosertib
Description 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.
