    摘要:
    本公开涉及双链寡核苷酸,包括双链寡核苷酸,例如siRNA,包括一个sense链寡核苷酸和一个antisense链寡核苷酸,其中antisense链寡核苷酸包括一个或多个公式(I-A)的核苷酸类似物,这些类似物既不是所述antisense链寡核苷酸的5'-突出核苷酸也不是3'-突出核苷酸,并且公式(I-A)的核苷酸类似物如所述。含有这些类似物的寡核苷酸具有优越的生物活性,例如增加的体外稳定性和改善的体内效力,特别是改善的非靶向作用谱。改进的寡核苷酸对于沉默(例如减少或根除)靶基因的表达是有用的。

    LNA(锁定核酸):腺嘌呤,胞嘧啶,鸟嘌呤,5-甲基胞嘧啶,胸腺嘧啶和尿嘧啶双环核苷单体的合成,寡聚化和前所未有的核酸识别
    摘要:
    由2'- O,4'- C-亚甲基双环核苷单体组成的LNA(锁定核酸)被有效合成,并评估了其对六种不同核碱基(腺嘌呤,胞嘧啶,鸟嘌呤,5-甲基胞嘧啶,胸腺嘧啶)的核酸识别潜力和尿嘧啶。当评估部分或完全修饰的LNA的混合序列时,双链体对DNA和RNA的热稳定性出现了前所未有的提高(每个修饰+3至+8°C)。错配序列的研究表明,与相应的未修饰参考链相比,LNA遵循具有普遍提高的选择性的Watson-Crick碱基配对规则。

    Molecular docking simulations revealed that compounds 2, 7, and 8 had a comparable binding affinity to cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes. Additionally, the bridged nucleoside analogs 7 and 8 potently inhibited adenosine kinase enzyme as well, which indicates an alternate mechanistic pathway behind their anti-nociceptive action.
