Description
Rigosertib (ON-01910 sodium salt), a synthetic benzyl styryl sulfone analogue with potential antineoplastic activity, is a non-ATP-competitive inhibitor of PLK1 (IC50=9 nM), 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.
