Application

Tegafur has been used as an internal standard for the analysis of 5′DFCR (5′deoxyfluorocytidine) and 5′DFUR (5′deoxyfluorouridine) using HPLC techniques. Tegafur has also been used as an internal standard for the chromatographic assay of azidothymidine (AZT).

Biochem/physiol Actions

Tegafur is a pro-drug of 5-fluorouracil, an antimetabolite used as an antineoplastic agent. It has been used as adjuvant chemotherapy for curatively resected colorectal cancer therapy.

Preparation Note

Hepatocellular carcinoma (HCC) is an intrinsically chemotherapy refractory malignancy. Development of effective therapeutic regimens would be facilitated by improved preclinical HCC models. Currently, most models consist of subcutaneous human tumor transplants in immunodeficient mice; however, these do not reproduce the

S-1 is an oral fluoropyrimidine that is designed to improve the antitumor activity of 5-fluorouracil (5-FU) concomitantly with an intent to reduce its toxicity. S-1 consists of tegafur, a prodrug of 5-FU combined with two 5-FU biochemical modulators:5-chloro-2,4-dihydroxypyridine (gimeracil or

Protracted intravenous regimens of fluorouracil (5-FU) may be superior and better tolerated than intravenous bolus dosing. An effective oral regimen would allow a protracted course of 5-FU without the need for central venous lines and the associated increase in complications.

The 5FU prodrug capecitabine undergoes a 3-step enzymatic conversion, including the conversion of 5'DFRC into 5'DFUR by cytidine deaminase (CDA). The presence of CDA activity in blood led us to analyze the possible ex vivo conversion of 5'DFCR into 5'DFUR
