Actions biochimiques/physiologiques

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).

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

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

This study evaluated the efficacy and safety of the combination drug tegafur, gimeracil, and oteracil potassium (S-1) concurrent with 3-dimensional conformal radiotherapy for newly diagnosed squamous cell carcinoma of the lung in elderly patients. Patients with pathologically or cytologically newly

The most common histological classification of bile duct cancer is adenocarcinoma and squamous cell carcinoma (SCC) is relatively rare. We report a case of a 78-year-old man with SCC of the extrahepatic bile duct associated with metachronous para-aortic lymph node

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
