  • LNA (Locked Nucleic Acids): Synthesis of the adenine, cytosine, guanine, 5-methylcytosine, thymine and uracil bicyclonucleoside monomers, oligomerisation, and unprecedented nucleic acid recognition

    日期:1998.4
    LNA (Locked Nucleic Acids), consisting of 2′-O,4′-C-methylene bicyclonucleoside monomers, is efficiently synthesized and its nucleic acid recognition potential evaluated for six different nucleobases, namely adenine, cytosine, guanine, 5-methylcytosine, thymine and uracil. Unprecedented increases (+3 to +8 °C per modification) in the thermal stability of duplexes towards both DNA and RNA were obtained
    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。

    on the bicyclo[2.2.1]heptane scaffold of locked nucleic acid (LNA) and tested them for both agonist and antagonist activity at the adenosine A(3) receptor. The design of these derivatives was based on the known A(3) agonist IB-MECA and related compounds. Modifications thus include the 5'-uronamides and N(6)-(3-iodobenzyl) derivatives. In this way we have prepared analogs of known A(3) agonists with
    我们基于锁定核酸(LNA)的双环[2.2.1]庚烷骨架制备了一系列腺苷类似物,并对其在腺苷A(3)受体上的激动剂和拮抗剂活性进行了测试。这些衍生物的设计基于已知的A(3)激动剂IB-MECA和相关化合物。因此,修饰包括5'-脲酰胺和N(6)-(3-碘苄基)衍生物。以这种方式,我们制备了已知的A(3)激动剂的类似物,其中糖环被限制在N-构象中。为了比较,我们还制备了IB-MECA的2'-O-甲基衍生物。LNA核苷无激动剂活性,但其中一些是有效的拮抗剂。IB-MECA的2'-O-甲基衍生物是与母体化合物具有相似效力的激动剂。

    A synthesis of [2.2.1]bicyclo nucleosides which is shorter and provides higher overall yields proceeds via the key intermediate of the general formula III, wherein R 4 and R 5 are, for instance, sulfonates and R 7 is, for instance, a halogen or an acetate. From compounds of the general formula II, such as 3-O-aryl-4-C-hydroxymethyl-1,2-O-isopropylidene-&agr;-D-ribofuranose, intermediates of the general formula III are suitable for coupling with silylated nucleobases. Upon one-pot base-induced ring-closure and desulfonation of the formed [2.2.1]bicyclo nucleoside, a short route to each the LNA (Locked Nucleic Acid) derivatives of adenosine, cytosine, uridine, thymidine and guanidine is demonstrated. The use of the 5′-sulfonated ring-closed intermediate also allows for synthesis of 5′-amino- and thio-LNAs. 1
    通过通式III的关键中间体进行合成[2.2.1]双环核苷,该方法较短且提供更高的总收率,其中R4和R5例如为磺酸盐,R7例如为卤素或醋酸盐。从通式II的化合物,例如3-O-芳基-4-C-羟甲基-1,2-O-异丙基亚-D-核糖,通式III的中间体适用于与硅化核苷碱进行偶联。通过一锅法碱催化环闭合和去磺酸化形成的[2.2.1]双环核苷,演示了腺嘌呤、胞嘧啶、尿嘧啶、胸腺嘧啶和鸟嘌呤的LNA(锁定核酸)衍生物的短路线。使用5'-磺酸化环闭合中间体还允许合成5'-氨基和硫代-LNA。
