2'-Deoxyadenosine-5'-monophosphate

2'-Deoxyadenosine-5'-monophosphate (CAS No.: 653-63-4) is a naturally occurring deoxyribonucleotide and an AMP-derived nucleic acid component that serves as a fundamental building block of DNA, where it participates in essential processes such as DNA synthesis, replication fidelity, and repair mechanisms. As a key intermediate in nucleotide metabolism, it contributes to the regulation of adenosine-related enzymatic pathways and signaling networks, influencing cellular responses to DNA damage and genomic stability. This molecule is widely utilized in biochemical and molecular biology research to investigate adenosine-mediated interactions, nucleotide incorporation, and enzyme kinetics involving DNA polymerases and repair enzymes, and it has also been employed in the development of modified nucleotides, including photoaffinity probes for studying nucleic acid–protein interactions. Although it does not function as a classical pharmacological inhibitor, its activity in experimental systems typically manifests through modulation of enzymatic processes at concentrations in the micromolar range, depending on assay conditions. In biomedical research and drug discovery, it is commonly applied in cell-free systems, cultured cells, and enzymatic assays to model nucleotide metabolism, evaluate DNA damage responses, and support the design of nucleoside-based therapeutics, with dosing or concentration parameters adjusted according to specific experimental objectives.
