Abstract 1328: Replication inhibition and mutagenicity of 8,5’-cyclopurine-2’-deoxynucleosides in Escherichia coli

open access: yes, 2011
8,5’-Cyclopurine-2’-deoxynucleosides are unique tandem DNA lesions formed by oxidation or ionizing radiation, which are repaired only by nucleotide excision repair. They have been suspected to be responsible for neurodegeneration and other diseases.

Induction of 8,5′-Cyclo-2′-deoxyadenosine and 8,5′-Cyclo-2′-deoxyguanosine in Isolated DNA by Fenton-Type Reagents

open access: yes
Exposure of aqueous solutions of DNA to X- or γ-rays, which induces the hydroxyl radical as one of the major reactive oxygen species (ROS), can result in the generation of a battery of single-nucleobase and bulky DNA lesions. These include the (5′R) and (

Stability of N‑Glycosidic Bond of (5′S)‑8,5′-Cyclo-2′-deoxyguanosine

open access: yes
8,5′-Cyclopurine deoxynucleosides are unique tandem lesions containing an additional covalent bond between the base and the sugar. These mutagenic and genotoxic lesions are repaired only by nucleotide excision repair. The N-glycosidic (or C1′-N9) bond of
