Application

5-Iodo-2′-deoxyuridine (5-IUdR; IdUrd) is a pyrimidine analog (halogenated thymidine) that has antiviral activity agains vaccinia virus (orthopoxviruses). IdUrd is used as a radiosensitizer in human cancer studies.
5-Iodo-2′-deoxyuridine has been used in molecular combing assay or DNA fiber assay.

Biochem/physiol Actions

5-Iodo-2′-deoxyuridine prevents in vitro DNA viral replication. This is observed in herpesviruses and poxviruses It might possess teratogenic, tumor-promoting, mutagenic, and immunosuppressive properties. 5-Iodo-2′-deoxyuridine, used in topical applications, is effective against epithelial infections.

Accelerated tumor cell repopulation is an important mechanism adversely affecting therapeutic outcome in head and neck cancer. The noninvasive assessment of the proliferative state of a tumor by PET may provide a selection tool for customized treatment. 3'-deoxy-3'-(18)F-fluorothymidine ((18)F-FLT) is

Iodine-enhanced synchrotron stereotactic radiotherapy takes advantage of the radiation dose-enhancement produced by high-Z elements when irradiated with mono-energetic beams of synchrotron X-rays. In this study it has been investigated whether therapeutic efficacy could be improved using a thymidine analogue, 5-iodo-2'-deoxyuridine
