idoxuridine

Definition / meaning of idoxuridine

An iodinated analogue of deoxyuridine. Idoxuridine incorporates into DNA during the S-phase of the cell cycle, sensitizing cells to ionizing radiation by increasing DNA strand breaks. When this agent contains a radioactive isomer of iodine, the radioactive idoxuridine kills cancer cells directly after preferential incorporation into the DNA of rapidly dividing tumor cells.
