Biochem/physiol Actions

Gimeracil (5-chloro-2, 4-dihydroxypyridine) is an orally active inhibitor against dihydropyrimidine dehydrogenase (DPYD), which degrades pyrimidine and the chemotherapeutic drug 5-fluorouracil (5FU). Gimeracil is shown to exhibit cancer-radiosensitizing efficacy in cultures in vitro (1 mM) and in mice in vivo (2.5-25 mg/kg, p.o.) in a DPYD-dependent manner via partial suppression of DNA repair by homologous recombination (HR).

Chemoradiotherapy is a useful treatment strategy in patients with locally advanced cancers. In particular, combination of 5-fluorouracil (5-FU) with X-ray irradiation is effective for the treatment of some types of gastrointestinal cancers. We investigated the antitumor effects of combination treatment

Gimeracil (5-chloro-2, 4-dihydroxypyridine) is an inhibitor of dihydropyrimidine dehydrogenase (DPYD), which degrades pyrimidine including 5-fluorouracil in the blood. Gimeracil was originally added to an oral fluoropyrimidine derivative S-1 to yield prolonged 5-fluorouracil concentrations in serum and tumor tissues. We have

It has not been elucidated whether the clinical efficacy of oral fluoropyrimidines for adjuvant chemotherapy of colorectal cancer varies with tumor biological characteristics. A multicenter randomized trial was performed comparing oral tegafur/gimeracil/oteracil (S-1) and uracil-tegafur/ leucovorin (UFT/LV) as adjuvant therapy
