Methyl groups of thymine and 5-methylcytosine (5mC) bases in DNA undergo endogenous oxidation damage. Additionally, 5mC residues can be enzymatically deaminated or oxidized through either genetic alterations or the newly identified epigenetic reprogramming pathway. Several methods have been developed to measure the formation of modified DNA nucleobases including 32P-postlabeling. However, the postlabeling method is often limited by the absence of authentic chemical standards. The synthesis of monophosphate standards of nucleotide oxidation products is complicated by the presence of additional functional groups on the modified bases that require complex protection and deprotection strategies. Due to the emerging interest in the pyrimidine oxidation products, the corresponding protected 3′-phosphoramidites needed for solid-phase oligonucleotide synthesis have been reported, and several are commercially available. We report here an efficient synthesis of 3′-monophosphates from 3′-phosphoramidites and the subsequent enzymatic conversion of 3′-monophosphates to the corresponding 5′-monophosphates using commercially available enzymes.
