8-Oxo-Benzylguanine is a chemical compound with applications in biochemistry and molecular biology. It is a derivative of benzylguanine, a simple aromatic compound that contains a reactive guanine group. One area of research on 8-Oxo-Benzylguanine is its use as a substrate for the enzyme alkylguanine DNA alkyltransferase (AGT). AGT is a DNA repair enzyme that plays a critical role in protecting cells from the effects of alkylating agents. By reacting with 8-Oxo-Benzylguanine, AGT can be inactivated, researchers have investigated the use of 8-Oxo-Benzylguanine as a building block for the synthesis of oligonucleotides. Because 8-Oxo-Benzylguanine is a relatively simple aromatic compound, it can be used to investigate fundamental chemical processes, such as nucleophilic substitution reactions, in a controlled setting.
