A lipophilic “fully-anti” dodecamer from a (5′S)-5′,8-cyclo-2′-deoxyguanosine
The self-assembly of a lipophilic derivative of (5'S)-5',8-cyclo-2'-deoxyguanosine, a mutagenic product formed by hydroxyl radical attack against DNA, has been investigated.

Oxidative stress and 8-oxoguanine repair are enhanced in colon adenoma and carcinoma patients. [PDF]
Oxidative stress is involved in the pathogenesis of colon cancer. We wanted to elucidate at which stage of the disease this phenomenon occurs. In the examined groups of patients with colorectal cancer (CRC, n = 89), benign adenoma (AD, n = 77) and ...

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

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 (

8-Fluoro-N-2-isobutyryl-2′-deoxyguanosine: Synthesis and Reactivity
3′,5′-O-Bis(tert-butyldimethylsilyl)-8-fluoro-N-2-isobutyryl-2′-deoxyguanosine was synthesized from 3′,5′-O-bis(tert-butyldimethylsilyl)-N-2-isobutyryl-2′-deoxyguanosine by the treatment with N-fluorobenzenesulfonimide.

Structures of (5′S)-8,5′-Cyclo-2′-deoxyguanosine Mismatched with dA or dT
Diastereomeric 8,5′-cyclopurine 2′-deoxynucleosides, containing a covalent bond between the deoxyribose and the purine base, are induced in DNA by ionizing radiation.

Chemistry and Biology of 8,5\u27-Cyclo-2\u27-deoxyguanosine and Other DNA Lesions
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 (NER). It was shown that the R-cdA is

Structure of (5′S)-8,5′-Cyclo-2′-deoxyguanosine in DNA
Diastereomeric 8,5′-cyclopurine 2′-deoxynucleosides, containing a covalent bond between the deoxyribose and the purine base, represent an important class of DNA damage induced by ionizing radiation.

Oxidation of 2'-Deoxyguanosine and 8-Oxo-2'-deoxyguanosine by Dimethyldioxirane [PDF]
Oxidative damage to DNA can lead to cancer, aging, and neurological disorders. Of the four DNA bases, guanine is the most susceptible to oxidation. To help us further our knowledge of how oxidation contributes to illness and disease, it is important to ...

Independent generation of C5 '-nucleosidyl radicals in thymidine and 2 '-deoxyguanosine
The synthesis of the C5' tert-butyl ketone of thymidine 1a and 2'-deoxyguanosine 2 is achieved by reaction of 5'-C-cyano derivatives with tert-butyl lithium followed by acid hydrolysis.
