    Oligodeoxyribonucleotide Phosphorothioates: Substantial Reduction of (N-1)-mer Content Through the Use of Trimeric Phosphoramidite Synthons
    摘要:
    Use of fully protected trimeric phosphoramidite synthons in the synthesis of oligonucleotide phosphorothioate shows a substantial reduction (>85%) in (n-1)-mer content as compared to oligomers synthesized through coupling of standard phosphoramidite monomers. A 20-mer oligodeoxyribonucleotide phosphorothioate which is in phase I clinical trials was chosen as an example for the studies.

    2,2,5,5-Tetramethylpyrrolidin-3-one-1-sulfinyl 基团用于 DNA 寡核苷酸固相制备中脱氧核糖核苷亚磷酰胺的 5'-羟基保护
    摘要:
    已经研究了几种氮硫试剂作为脱氧核糖核苷亚磷酰胺的潜在 5'-羟基保护基团,以改善玻璃微阵列上寡核苷酸的合成。在迄今为止研究的氮硫基保护基团中,2,2,5,5-四甲基吡咯烷-3-one-1-亚磺酰基由于其温和性而表现出近乎最佳的 5'-羟基保护性质。脱保护条件。具体而言,在控制孔玻璃上合成 5'-d(ATCCGTAGCCAAGGTCATGT) 时,末端 5'-亚磺酰胺基团的迭代裂解是通过在酸性盐的存在下用碘处理来有效完成的。寡核苷酸水解为其 2' -脱氧核糖核苷暴露于蛇毒磷酸二酯酶和细菌碱性磷酸酶后未显示任何核碱基加合物或其他修饰的形成。这些发现表明,用于亚磷酰胺 5'-羟基保护的 2,2,5,5-四甲基吡咯烷-3-one-1-亚磺酰基,如 10a-d,可能导致寡核苷酸微阵列的产生,其表现出增强的特异性和检测核酸靶标的灵敏度。

  • Building Blocks for the Solution Phase Synthesis of Oligonucleotides:  Regioselective Hydrolysis of 3‘,5‘-Di-<i>O</i>-levulinylnucleosides Using an Enzymatic Approach

    opposite selectivity toward the hydrolysis at the 3'-position, affording 5'-O-levulinyl derivatives 4 in >70% yields. A similar hydrolysis procedure was successfully extended to the synthesis of 3'- and 5'-O-levulinyl-protected 2'-O-alkylribonucleosides 7 and 8. This work demonstrates for the first time application of commercial CAL-B and PSL-C toward regioselective hydrolysis of levulinyl esters with excellent
    通过区域选择性酶水解反应,由相应的3',5'-二-O-乙酰丙酰衍生物开发了一种简便的3'-和5'-O-乙酰丙酰-2'-脱氧核苷合成方法,避免了一些繁琐的化学保护/脱保护步骤。因此,发现南极假丝酵母脂肪酶B(CAL-B)选择性地水解5'-乙酰丙酸酯,以> 80%的分离产率提供3'-O-乙酰丙酰-2'-脱氧核苷3。另一方面,固定化的假单胞菌洋葱脂肪酶(PSL-C)和南极假丝酵母脂肪酶A(CAL-A)在3'-位置对水解表现出相反的选择性,从而在> 70的情况下提供5'-O-乙酰丙酰衍生物4 %产率。相似的水解过程已成功扩展到3'-和5'-O-乙酰丙氨酰保护的2'的合成 -O-烷基核糖核苷7和8。这项工作首次证明了商业CAL-B和PSL-C在乙酰丙酸酯的区域选择性水解方面具有优异的选择性和产率。值得注意的是,受保护的胞苷和腺苷碱衍生物不足以用作用CAL-B进行酶促水解的底物,而PSL-C能够在选择

    An efficient synthetic approach to protected trinuclotide phosphoramidites suitable for codon-by-codon synthesis of structural gene combinatorial libraries is described; the procedure rests on the use of pair of orthogonal protecting groups for the two oligomer termini and offers flexibility in the choice of chain elongation direction going from dimer to trimer.

  • Investigation of a Facile Synthetic Method for Phosphorothioate Dimer Synthons In Oligonucleotide Phosphorothioates Synthesis
    作者:Takanori Miyashita、Kohei Yamada、Kazuhiko Kondo、Kenya Mori、Kazuo Shinozuka
    DOI:10.1080/15257770008033035
    日期:2000.5
    A facile synthetic method of a phosphorothioate dimer block was investigated. Dinucleoside phosphite triester intermediates were obtained in one-pot synthesis by the coupling of a protected nucleoside bearing free 5'-OH and a protected nucleoside bearing free 3'-OH in the presence of phosphorous trichloride (PCl3) and 1,2,4-triazole. The intermediates were easily sulfurized to afford the desired phosphorothioate dimer blocks in 33-64% overall yields.
