| Hazard Information | Back Directory | [Description]
Eniluracil (59989-18-3) is an irreversible dihydropyrimidine dehydrogenase (DPD) inhibitor.1-3? DPD is involved in the degradation of pyrimidine-based chemotherapeutic drugs such as 5-fluorouracil (5-FU).? Eniluracil has been used along with 5-FU to prolong circulating concentrations of the drug. | [Uses]
Potent inactivator of Dihydropyrimidine dehydrogenase (DPD). | [Definition]
ChEBI: Eniluracil is a pyrimidone. | [References]
