Key Points

The aim is to understand the one-electron reduction of 8-Br-dA and 8-Br-dG and its significance in biological systems.
Analysis of electron attachment mechanisms using radiation chemistry principles.
Evaluation of the roles of 8-Br-dA and 8-Br-dG in the context of radiation exposure.
Enhanced understanding of how 8-bromo-purine derivatives affect DNA damage.

Abstract

Based on radiation chemistry, our understanding of the one-electron reduction of 8-Br-dA and 8-Br-dG has been enhanced substantially. This mechanistic background is crucial for a better understanding of and addressing their significant roles in the biological environment, such as DNA radiosensitizers for cancer radiation therapy or as biomarkers for early inflammation.
