Rigosertib (ON-01910 sodium salt, with Estybon as trade name) is a synthetic benzyl styryl sulfone in development by Onconova Therapeutics.[1] Riosertib is in phase III clinical trials for the treatment of chronic myelomonocytic leukemia.[2]

Its geometrical isomer (Z)-ON 01910·Na has less cytotoxicity on cancer cells.

Mechanism[edit]

Rigosertib is a microtubule-destabilizing agent.[3]
