Rigosertib sodium (Cat.No:I004220) is an investigational anticancer drug that belongs to the class of small-molecule inhibitors targeting the Ras and PI3K pathways. It acts by inhibiting the enzyme RAS, which plays a critical role in cancer cell growth and proliferation. Rigosertib sodium is being studied in clinical trials for its potential efficacy in various cancer types.
