  Oligonucleotides Containing Pyrazolo[3,4-d]pyrimidines: The Influence of 7-Substituted 8-Aza-7-deaza-2′-deoxyguanosines on the Duplex Structure and Stability

  摘要：

  Oligonucleotides containing 7-substituted 8-aza-7-deazaguanines (= 6-amino-1,5-dihydro-4H-pyrazolo[3.4-d]pyrimidin-4-ones) were prepared by automated solid-phase synthesis. A series of 7-alkynylated 8-aza-7-deaza-2'-deoxyguanosines (see 4a-d)were synthesized with the 7-iodonucleoside 3c as starting material and by the Pd-0/Cu-I-catalyzed cross-coupling reaction with various alkynes. Phosphoramidites were prepared from the 7-substituted 8-aza-7-deaza-2'-deoxyguanosine derivatives carrying halogeno, cyano, and hexynyl substituents. From the melting profiles of oligonucleotide duplexes. the T-m values as well as the thermodynamic data were determined. A significant duplex stabilization by the 7-substituents was observed for the DNA . DNA duplexes, but not in the case of DNA . RNA hybrids.
