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.
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
