• General Description: 8-OXO-2'-DEOXYGUANOSINE (also known as 8-hydroxy-2'-deoxyguanosine or oh8dG) is a well-established biomarker of oxidative DNA damage, implicated in processes such as carcinogenesis, mutagenesis, and toxicology. It is commonly quantified using analytical techniques like GC-MS, where isotopically labeled analogs, such as 8-[18O]hydroxy-2'-deoxyguanosine, serve as internal standards for accurate measurement. 8-OXO-2'-DEOXYGUANOSINE arises from oxidative stress-induced modifications to guanine bases in DNA, reflecting cellular exposure to reactive oxygen species. Its detection is critical in assessing oxidative damage in biological samples, including DNA and urine.

Synthesis of 8-[¹⁸O]hydroxy-2'-deoxyguanosine

10.1002/jlcr.2580340213

The research aims to develop a method for synthesizing 8-[18O]hydroxy-2'-deoxyguanosine (8-[18O]OH-dG) to be used as an internal standard for the quantification of 8-hydroxy-2'-deoxyguanosine (oh8dG) by GC-MS. oh8dG is a significant marker of oxidatively damaged DNA, which is relevant in carcinogenesis, mutagenesis, and toxicology. The synthesis process involves several steps, starting with the bromination of 2'-deoxyguanosine to produce 8-bromo-2'-deoxyguanosine, followed by the conversion to 8-[18O]benzyloxy-2'-deoxyguanosine using the sodium salt of [18O]benzyl alcohol, and finally, the reduction to 8-[18O]hydroxy-2'-deoxyguanosine through catalytic transfer hydrogenation. Key chemicals used include 2'-deoxyguanosine, bromine, ethyl benzimidate hydrochloride, H218O, LiAlH4, sodium hydride, and palladium on carbon. The overall yield of 8-[18O]OH-dG from H218O was approximately 4%, with an isotopic purity of 93.4 atom% as determined by GC-MS. The synthesized compound meets the required purity standards for its intended application as an internal standard in the analysis of oh8dG extracted from in vivo DNA and urine.
