Abstract: 3-(2-Deoxy-β-d-erythropentofuranosyl)pyrimido[1,2-a]purin-10(3H)-one (M1dG) is an endogenous DNA adduct in bacterial and mammalian cells that could be explored as a biomarker for oxidative stress. Nonetheless, the lack of an efficient methodology for the preparation of M1dG hampers… read more here.

Abstract: : Exposure of infants to antiretroviral drugs for prevention of mother-to-child transmission can induce resistance to nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs). Data from nine national surveys of pretreatment drug resistance in children newly diagnosed with… read more here.

Abstract: BACKGROUND Modified nucleoside and nucleotide analogs are now the cornerstone of antiviral and anticancer chemotherapies. However, these compounds are not active on their own and need, after entering the cell, to be metabolized to their… read more here.
