Background

Rigosertib is a dual inhibitor of phosphoinositide 3-kinase (PI3K) and polo-like kinase 1 (PLK1) [1].

In vitro studies show that rigosertib inhibits the PI3K/AKT pathway, down-regulates cyclin D1, induces NOXA and BIM and activates the JNK pathway in human leukemic cells. Rigosertib induces apoptosis of a variety of human tumor cell lines including breast, prostate, ovarian, pancreatic, SCLC, colorectal, melanoma and et al. For instant, it shows anti-tumor efficacy in BT20, MCF-7, BT474, OV-CAR-3, A549 and HCT-116 with IC50 values of 80nM, 75nM, 50nM, 75nM, 90nM and 75nM, respectively. In addition, rigosertib is also effective against the drug resistant tumor cell lines. It potently inhibits tumor growth with IC50 values of 100nM and 50nM against MES-SA/DX5 and CEM/C2, respectively. Moreover, it is reported that rigosertib can affect the cell cycle of both normal cells and tumor cells. Rigosertib leads to a blockade of cell cycle progression in the G1 and G2/M phases in normal diploid human fetal lung cells. When treated with DU145 cells, rigosertib induces cell cycle arrest in G2/M phase [2].
