Description

Ropidoxuridine (IPdR) is a halogenated pyrimidine nucleoside analog that functions as a radiosensitizing agent in cancer treatment. This compound is specifically designed to enhance the effectiveness of radiation therapy by incorporating into DNA and making cancer cells more vulnerable to radiation damage. In colorectal cancer treatment, ropidoxuridine is being evaluated in combination with standard chemotherapy agents like capecitabine during radiation therapy protocols, particularly for rectal cancer patients.

Mechanism of Action

Ropidoxuridine works by incorporating into the DNA of rapidly dividing cancer cells during DNA synthesis, replacing thymidine in the DNA structure. Once incorporated, the halogenated nucleo
