Nucleoside phosphoramidates (NPs) are a class of nucleotide analogues that has been developed as potential antiviral/antitumor prodrugs. Recently, we have shown that some amino acid nucleoside phosphoramidates (aaNPs) can act as substrates for viral polymerases like HIV-1 RT. Herein, we report
2-Amino-7-deazaadenine ((AD)A) was incorporated into oligodeoxynucleotides (ODN) and their base-pairing properties with natural nucleobases were investigated. In melting temperature (T(m)) experiments, the duplex containing an (AD)A/C base pair showed a high stability comparable to that containing (AD)A/T base pair. Destabilization

(Cytosin-5-yl)ethynyl derivatives of pyrimidine and 7-deazaadenine 2-deoxyribonucleosides and nucleoside triphosphates (dNTPs) were prepared in one step by the aqueous Sonogashira coupling of unprotected halogenated nucleos(t)ides with 5-ethynylcytosine. The modified dNTPs were good substrates for DNA polymerases suitable for primer extension
Deoxydecanucleotides having a recognition sequence of Bgl II and Sau 3AI, and their 7-deazaadenine analogs were synthesized. The decanucleotides containing 7-deazaadenine in place of adenine were partially resistant to the hydrolysis by Sau 3AI and strongly resistant to that by
Interest in using DNA as a building block for nanoelectronic sensors and devices stems from its efficient hole-conducting properties and the relative ease with which it can be organized into predictable nanometre-sized two- and three-dimensional structures. However, because a hole
