Application
Tegafur: A Prodrug of an Active Antitumor 5-FU
Tegafur is a prodrug that is metabolized by cytochrome P 450 to an active antitumor 5-FU [F0151]. Tegafur is often used as combined agents such as UFT (tegafur and uracil [U0013] at a molar ratio of 1:4) or S-1 (tegafur, gimeracil [C2243] and potassium oxonate [O0164] at a molar ratio of 1:0.4:1) to increase the plasma and tumor 5-FU concentrations. Determination of the combined agents in plasma is important to evaluate the safety and efficacy of them. (The product is for research purpose only.)
