| Hazard Information | Back Directory | [Description]
Gimeracil (103766-25-2) is a dihydropyrimidine dehydrogenase (DPD) inhibitor.? DPD is involved in the degradation of pyrimidine-based chemotherapeutic drugs such as 5-fluorouracil (5-FU).? Gimeracil is used along with 5-FU or Tegafur to prolong circulating concentrations of the drugs.1,2? Gimeracil has also been shown to act as a radiosensitizer via inhibition of homologous recombination in the repair of DNA double strand breaks.3 | [Chemical Properties]

Antitumor agent. A potent inhibitor of dihydropyrimidine dehydrogenase (DPD) | [Uses]
Gimeracil is an antitumor agent. Gimeracil is a potent inhibitor of dihydropyrimidine dehydrogenase (DPD). | [Uses]
Gimeracil is an inhibitor of dihydropyrimidine dehydrogenase, which inhibits the early step in homologous recombination for double strand breaks repair. | [Definition]
ChEBI: Gimeracil is an organic molecular entity. | [in vivo]
Gimeracil (2.5-25 mg/kg, orally) may inhibit the rapid repair of X-ray-induced DNA damage in tumors[3].
| Animal Model: | Nude mice (Lu-99, LC-11, KB/C3 and PAN-4 tumors were xenografted)[3].
| | Dosage: | 2.5-25 mg/kg. | | Administration: | Orally. | | Result: | Exhibited anti-tumor activity. |
