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 ribose fragments of ribonucleotides, thereby preventing the formation of enzyme-substrate complexes, thereby preventing chain elongation, It can also inhibit DNA synthesis by binding deoxyribose fragments of DNA and preventing DNA polymerase from adding nucleotides to the growth chain. 3-Deaza-2 '-deoxyadenosine has antiviral activity[1][2].
