چکیده
A first derivative spectrometric method has been developed for the determination of the 5-fluorouracil and N1(2'-furanidyl)uracil related substances and degradation products of tegafur. The wavelengths selected for the determination of 5-fluorouracil and N1(2'-furanidyl)uracil were 298 and 288 nm, respectively. At this wavelength, the calibration graphs between the amplitude of the signals and the concentration of each compound were linear up to 24.75 mg l(-1) for 5-fluorouracil and up to 20.20 mg l(-1) for N1(2'-furanidyl)uracil. The detection limits were 0.40 and 0.050 mg l(-1) for 5-fluorouracil and N1(2'-furanidyl)uracil, respectively. The method is simple and rapid and does not require any preliminary treatment of the sample. The method was validated.

متن کاملUFT: East meets West in drug development.
Although the combination of uracil and tegafur (UFT) has been available commercially in Japan since 1984 and is one of the most extensively prescribed antineoplastic agents in that country, few physicians outside Japan have knowledge of and experience with the drug. The development of UFT, which combines uracil and tegafur in a 4:1 molar concentration, dates back to the pioneering work of Fujii...
