3-deaza-2'-deoxyadenosine

3-Deaza-2'-deoxyadenosine is a nucleoside analog synthesized from 2'-deoxyadenosine.3-Deaza-2'-deoxyadenosine inhibits RNA synthesis by binding to the ribose moiety of ribonucleotides, preventing the formation of enzyme-substrate complexes and chain elongation.It can also inhibit DNA synthesis by binding to the deoxyribose moiety of DNA and blocking the addition of nucleotides to the growing chain by DNA polymerases.3-Deaza-2'-deoxyadenosine exhibits antiviral activity.
