Synthesis of α-l-Threofuranosyl Nucleoside Triphosphates (tNTPs)
摘要:
[GRAPHICS]The alpha-L-threofuranosyl nucleoside triphosphates of T, G, and D (tTTP, tGTP, and tDTP) were synthesized from the described 2'-O-DMT-protected derivatives using the Eckstein method, while the corresponding C derivative (tCTP) was prepared from the 2'-O-acetyl derivative. The prepared alpha-L-threofuranosyl nucleoside triphosphates, despite being one carbon shorter than the native 2'-deoxyfuranosyl nucleoside triphosphates, are effective substrates for selected DNA polymerases.

polymers composed of TNA (α-l-threofuranosyl-(3′,2′) nucleicacid). This property, coupled with enhanced nuclease stability relative to natural DNA and RNA, warrants further investigation into the structural and functional properties of TNA as an artificial genetic polymer for synthetic biology. Here, we report a highly optimized chemical synthesis protocol for constructing multigram quantities of TNA
A TNA loop modified primer pair was designed to construct a stable terminal-closed linear gene, which can be used as an efficient gene expression system in eukaryotic cells.

[GRAPHICS]Cytosine TNA promotes nonenzymatic, template-directed oligomerization of complementary activated rGMP, leading to selective and efficient formation of RNA products. This process models "genetic takeover" of a pre-RNA by RNA.
The -L-Threofuranosyl-(3′→2′)-oligonucleotide System (‘TNA'): Synthesis and Pairing Properties
α-L-Threofuranosyl-(3′2′)-oligonucleotides (‘TNA') are part of a systematic experimental inquiry into the base-pairing properties of potentially natural nucleic acid alternatives taken from RNA's close structural neighborhood. TNA is an efficient Watson-Crick base-pairing system and has the capability of informational cross-pairing with both RNA and DNA. This property, together with the system's constitutional
