  Synthesis and one-electron reduction characteristics of radiation-activated prodrugs possessing two 5-fluorodeoxyuridine units

  摘要：

  Two molecules of an antitumor agent, 5-fluorodeoxyuridine (5-FdUrd), were connected by a 2-oxoalkyl linker (Oxo-linker) at the N(3) position to obtain radiation-activated prodrugs, FdUrd(2) A and FdUrd(2) B. The prodrugs in this study released 5-FdUrd via one-electron reduction initiated by hypoxic X-irradiation. The release of 5-FdUrd from FdUrd(2) A and FdUrd(2) B proceeded more efficiently than that of previous prodrug, Oxo-FdUrd, which possessed one molecule of 5-FdUrd. FdUrd(2) A exhibited increased cytotoxicity against A549 cells when the FdUrd(2) A solution had been irradiated with a large dose of X-rays before administration to the cells. However, we observed no effect on cytotoxicity when the cells were X-irradiated under hypoxic conditions in the presence of FdUrd(2) A because the amount of 5-FdUrd released in the cells seemed to be too low to induce cytotoxic activity.
