  α,β-Methylene-2′-deoxynucleoside 5′-Triphosphates as Noncleavable Substrates for DNA Polymerases: Isolation, Characterization, and Stability Studies of Novel 2′-Deoxycyclonucleosides, 3,5′-Cyclo-dG, and 2,5′-Cyclo-dT

  摘要：

  We report synthesis and characterization of a complete set of alpha,beta-methylene-2'-dNTPs (alpha,beta-m-dNTP; N = A, C, T, G, 12-15) in which the alpha,beta-oxygen linkage of natural dNTP was replaced by a methylene group. These nucleotides were designed to be noncleavable substrates for DNA polymerases. Synthesis entails preparation of 2'-deoxynucleoside 5'-diphosphate precursors, followed by an enzymatic gamma-phosphorylation. All four synthesized alpha,beta-m-dNTPs were found to be potent inhibitors of polymerase beta, with K-i values ranging 1-5 mu M. During preparation of the dG and dT derivatives of alpha,beta-methylene diphosphate, we also isolated significant amounts of 3,5'-cyclo-dG (16) and 2,5'-cyclo-dT (17), respectively. These novel 2'-deoxycyclonucleosides were formed via a base-catalyzed intramolecular cyclization (N3 -> C5' and O2 -> C5' respectively). In acidic solution, both 16 and 17 underwent glycolysis, followed by complete depurination. When exposed to alkaline conditions, 16 underwent an oxidative deamination to produce 3,5'-cyc1o-2'-deoxyxanthosine (19), whereas 17 was hydrolyzed exclusively to dT.
