5-Fluorouracil-13C,15N2 is the 13C and 15N labeled 5-Fluorouracil[1]. 5-Fluorouracil (5-FU) is an analogue of uracil and a potent antitumor agent. 5-Fluorouracil affects pyrimidine synthesis by inhibiting thymidylate synthetase thus depleting intracellular dTTP pools. 5-Fluorouracil induces apoptosis and can be used as a chemical sensitizer[2][3]. 5-Fluorouracil also inhibits HIV[4].
