Abstract

We prepared a 5-fluorodeoxyuridine (5-FdUrd) derivative possessing azide methyl group (N(3)-FdUrd) as a novel radiation-activated prodrug. The parent antitumor agent, 5-FdUrd, was released efficiently from N(3)-FdUrd by hypoxic X-irradiation. On the Other hand, the activation of N(3)-FdUrd was suppressed upon X-irradiation under aerobic conditions. A biological assay using A549 cells revealed that the cytotoxicity of N(3)-FdUrd was significantly enhanced by hypoxic X-irradiation.
