DFP-11207 is an orally active fluoropyrimidine cytotoxic agent. DFP-11207 combines a 5-FU (HY-90006) pro-drug with a reversible DPD inhibitor and a potent inhibitor of OPRT, resulting in enhanced pharmacological activity of 5-FU with decreased gastrointestinal and myelosuppressive toxicities. DFP-11207 can be used for the research of cancer [1].
