  两亲物的高通量合成和相表征：一个很好的案例研究

  摘要：

  提出了一种通过使用高通量（HT）方法合成和表征含有半乳糖和葡萄糖的两亲化合物文库的发现两亲化合物的新方法。用铜催化的叠氮化物-炔烃环加成（CuAAC）叠氮化物连接的单糖和炔烃取代的疏水尾巴之间的“点击”反应以24小瓶阵列格式合成了具有系统性链长和不饱和度变化的化合物库。通过使用同步加速器小角度X射线散射（SSAXS），以HT方式表征了液晶相的行为。讨论了观察到的关于链参数的结构变化，包括链长和不饱和度，以及水合效应和首基之间的氢键结合程度。我们的HT筛选方法的有效性通过重新合成短链葡萄糖两亲物来验证。对该化合物进行的单独相分析证实了许多溶致液晶相的存在。

  Synthesis and Biophysical Properties of C5-Functionalized LNA (Locked Nucleic Acid)

  摘要：

  Oligonucleotides modified with conformationally restricted nucleotides such as locked nucleic acid (LNA) monomers are used extensively in molecular biology and medicinal chemistry to modulate gene expression at the RNA level. Major efforts have been devoted to the design of LNA derivatives that induce even higher binding affinity and specificity, greater enzymatic stability, and more desirable pharmacokinetic profiles. Most of this work has focused on modifications of LNA's oxymethylene bridge. Here, we describe an alternative approach for modulation of the properties of LNA: i.e., through functionalization of LNA nucleobases. Twelve structurally diverse CS-functionalized LNA uridine (U) phosphoramidites were synthesized and incorporated into oligodeoxyribonucleotides (ONs), which were then characterized with respect to thermal denaturation, enzymatic stability, and fluorescence properties. ONs modified with monomers that are conjugated to small alkynes display significantly improved target affinity, binding specificity, and protection against 3'-exonucleases relative to regular LNA. In contrast, ONs modified with monomers that are conjugated to bulky hydrophobic alkynes display lower target affinity yet much greater 3'-exonuclease resistance. ONs modified with C5-fluorophore-functionalized LNA-U monomers enable fluorescent discrimination of targets with single nucleotide polymorphisms (SNPs). In concert, these properties render C5-functionalized LNA as a promising class of building blocks for RNA-targeting applications and nucleic acid diagnostics.

  Major efforts are currently being devoted to improving the binding affinity, target specificity, and enzymatic stability of oligonucleotides used for nucleic acid targeting applications in molecular biology, biotechnology, and medicinal chemistry. One of the most popular strategies toward this end has been to introduce additional modifications to the sugar ring of affinity-inducing conformationally restricted nucleotide building blocks such as locked nucleic acid (LNA). In the preceding article in this issue, we introduced a different strategy toward this end, i.e., C5-functionalization of LNA uridines. In the present article, we extend this strategy to alpha-L-LNA: i.e., one of the most interesting diastereomers of LNA. alpha-L-LNA uridine monomers that are conjugated to small C5-alkynyl substituents induce significant improvements in target affinity, binding specificity, and enzymatic stability relative to conventional alpha-L-LNA. The results from the back-to-back articles therefore suggest that C5-functionalization of pyrimidines is a general and synthetically straightforward approach to modulate biophysical properties of oligonucleotides modified with LNA or other conformationally restricted monomers.
