Development of a Method for Producing and Purifying N2-Carboxyethyl-2'-Deoxyguanosine for Molecular-Biological Research

Methylglyoxal (MG) – is a high reactive α- oxoaldehyde, which can be synthesized through various biochemical processes in vivo. MG is capable of interacting with nucleophilic groups of proteins, lipids and nucleic acids which leads to their glycation. Covalent compounds that formed in this process were named advanced glycation end products. Advanced glycation end products play an important role in the pathogenesis of diabetes, chronic inflammation, cancer and Alzheimer's disease. One of the most stable compounds, which is formed by reacting of methylglyoxal with the nitrogenous bases of the DNA molecule is N2- carboxyethyl -2' - deoxyguanosine (CEdG). This compound can be used as a marker for monitoring of various diseases, investigation of the role of glycation end products in their pathogenesis, as well as to search for the therapeutic targets. To perform our molecular-biological investigations by mass spectrometry, we synthesized N2- carboxyethyl -2' - deoxyguanosine, and have proposed a new method for purifying compounds by reverse - phase HPLC. As a result, we achieved the optimal purity of the sample, while substantially reducing the cost of the purification procedure.
