    4′-C-乙酰胺甲基-2′-O-甲氧基乙基核酸修饰可提高小干扰 RNA 的热稳定性、核酸酶抗性、效力和 hAgo2 结合
    摘要:
    在本研究中,我们设计了4′- C-乙酰胺甲基-2′- O-甲氧基乙基(4′- C -ACM-2′- O -MOE)尿苷和胸苷修饰,旨在测试它们在小干扰RNA中的作用。热熔解研究表明,在 DNA 双链体中掺入单个 4'- C -ACM-2'- O -MOE 修饰会降低热稳定性。相反,当在 DNA:RNA 杂交体和 siRNA 中引入修饰时,观察到热稳定性增加。 DNA双链体的热失稳归因于不利的熵,这在一定程度上主要由焓因子补偿。在 3' 特异性核酸外切酶、蛇毒磷酸二酯酶 (SVPD) 存在下,dT 20 寡核苷酸 3' 末端倒数第二个位置上的单个 4'- C -ACM-2'- O -MOE 胸苷修饰显示出显着的修饰作用。与包括 2'- O -Me、2'- O -MOE 和 2'-F 在内的单体修饰相比,稳定性更高。在基因沉默研究中,我们发现过客链3'突出端的4'- C -ACM-2'- O

    摘要:
    报道了四种新型 3'-C-支链和 4'-C-支链核苷的合成及其转化为相应的 3'-O-亚磷酰胺结构单元以用于自动寡核苷酸合成。4'-C-支化关键中间体11通过收敛策略合成并转化为其2'-O-甲基和2'-脱氧-2'-氟衍生物,从而制备出含有4'-的新型寡核苷酸类似物C-(氨基甲基)-2'-O-甲基单体X和4'-C-(氨基甲基)-2'-脱氧-2'-氟单体Y(方案2和3)。一般来说,与未修饰的参考相比,这些类似物对互补单链 DNA 和 RNA 的结合亲和力增加(表 1)。2'-O-甲基-RNA寡核苷酸中单体X或单体Y的存在对2'-O-甲基-RNA寡核苷酸对DNA和RNA的结合亲和力具有负面影响。从 3'-C-烯丙基衍生物 28 开始,合成了 3'-C-(3-氨基丙基)-保护的核苷和 3'-O-亚磷酰胺衍生物,从而产生了含有 3'-C-(3-氨基丙基)胸苷单体Z或相应的3'-C-(3-氨基丙基)-2'-O

  • Synthesis, Gene Silencing, and Molecular Modeling Studies of 4′-<i>C</i>-Aminomethyl-2′-<i>O</i>-methyl Modified Small Interfering RNAs

    The linear syntheses of 4'-C-aminomethyl-2'-O-methyl uridine and cytidine nucleoside phosphoramidites were achieved using glucose as the starting material. The modified RNA building blocks were incorporated into small interfering RNAs (siRNAs) by employing solid phase RNA synthesis. Thermal melting studies showed that the modified siRNA duplexes exhibited slightly lower T-m (similar to 1 degrees C/modification) compared to the unmodified duplex. Molecular dynamics simulations revealed that the 4'-C-aminomethyl-2'-O-methyl modified nucleotides adopt South-type conformation in a siRNA duplex, thereby altering the stacking and hydrogen-bonding interactions. These modified siRNAs were also evaluated for their gene silencing efficiency in HeLa cells using a luciferase-based reporter assay. The results indicate that the modifications are well tolerated in various positions of the passenger strand and at the 3' end of the guide strand but are less tolerated in the seed region of the guide strand. The modified siRNAs exhibited prolonged stability in human serum compared to unmodified siRNA. This work has implications for the use of 4'-C-aminomethyl-2'-O-methyl modified nucleotides to overcome some of the challenges associated with the therapeutic utilities of siRNAs.
