    Phospho-carboxylic anhydride of a homologated nucleoside leads to primer degradation in the presence of a polymerase
    摘要:
    Starting from thymidine, through a series of key synthetic transformations (e.g., Wittig reaction, hydroboration, Mitsunobu reaction and TEMPO oxidation) a nucleoside homologue bearing a phospho-carboxylic anhydride group at 60 position was synthesized. The potential of polymerases to catalyze amide bond formation was investigated by using a modified primer with an amino group at 3' position and the synthesized phosphoanhydro compound as substrate. Unfortunately, we did not observe the desired product either by gel electrophoresis or mass spectrometry. In contrast, the instability of the phosphoanhydro compound could lead to pyrophosphate formation and thus, to pyrophosphorolysis of the primer rather than to primer extension. (C) 2014 Elsevier Ltd.

    摘要:
    本发明揭示了一些改性核苷酸,由改性糖基组成,其中包含在脱氧核糖或核糖的C1和C4位置具有取代基,或在C3和C5位置具有分支取代基。每个核苷酸都被转化或适当保护,然后转化为相应的磷酰胺酯。这些磷酰胺酯用于组装寡核苷酸,在其中至少有一个上述核苷酸。这些糖修饰的寡核苷酸具有作为反义疗法的潜力,因为它们预计能够增强核酸酶抵抗力和细胞摄取,同时在体内或体外维持序列特异性和亲和力与核酸靶标。

    In this study, we designed 5′-amino-5′-deoxy-5′-hydroxymethylthymidine as a new oligonucleotide modification with an amino group directly attached to the 5′-carbon atom. We successfully synthesized two isomers of 5′-amino-5′-deoxy-5′-hydroxymethylthymidine via dihydroxylation of the 5′-vinyl group incorporated into 5-deoxy-5′-C-methenylthymidine derivartive. Moreover, it was found that the nuclease

    A nucleoside with two nucleobases, a so-called double-headed nucleoside, 5'(S)-C-(thymine-1-ylmethyl)thymidine 3, is synthesised and incorporated into oligonucleotides. The additional nucleobase is hereby positioned in the minor groove of the duplexes, which are formed with complementary DNA and RNA-sequences. Slight thermal destabilisation of these duplexes as compared to unmodified duplexes is observed
