  用于固相合成确定的聚酰胺酰胺的新型Fmoc-聚氨基酸

  摘要：

  开发了一种通用的固相方法，用于确定序列的聚酰胺胺。四种不同的Fmoc-聚氨基酸结构单元是通过对对称的低聚乙炔亚胺前体进行选择性保护，然后使用环酐引入羧酸的处理方法以及随后的Fmoc保护来合成的。新型Fmoc-聚氨基酸用于构建聚酰胺酰胺，证明与标准Fmoc反应条件完全相容。结构单元的直接合成和固相偶联反应的高效率使所定义的聚阳离子的多功能合成成为可能。

  Trehalose Click Polymers Inhibit Nanoparticle Aggregation and Promote pDNA Delivery in Serum

  摘要：

  Herein, three new glycopolymers have been synthesized via "click polymerization" to promote nucleic acid delivery in the presence of biological media containing serum. These structures were designed to contain a trehalose moiety to promote biocompatibility, water solubility, and stability against aggregation, amide-triazole groups to enhance DNA binding affinity, and an oligoamine unit to facilitate DNA encapsulation, phosphate neutralization, and interactions with cell surfaces. A 2,3,4,2', 3', 4'-hexa-O-acetyl-6,6'-diazido-6,6'-dideoxy-(D)-trehalose (4) monomer was polymerized via copper(I)-catalyzed azide-alkyne cycloaddition with a series of dialkyne-amide comonomers that contain either one, two, or three Boc-protected secondary amines (7a, 7b, or 7c, respectively). After deprotection, three water-soluble polycations (9a, 9b, or 9c) were obtained with similar degrees of polymerization (n = 56-61) to elucidate the role of amine number on nucleic acid binding, complex formation, stability, and cellular delivery. Gel electrophoresis and ethidium bromide experiments showed that 9a-9c associated with plasmid DNA (pDNA) and formed complexes (polyplexes) at N/P ratios dependent on the amine number. TEM experiments revealed that 9a-9c polyplexes were small (50-120 nm) and had morphologies (spherical and rodlike) associated with the polymer chain stiffness. Dynamic light scattering studies in the presence of media containing serum demonstrated that 9c polyplexes had a low degree of flocculation, whereas 9a and 9b polyplexesd aggregate rapidly. Further biological studies revealed that these structures were biocompatible and deliver pDNA into HeLa cells. Particularly, 9c polyplexes promoted high delivery efficacy and gene expression profiles in the presence of serum.

  expanded CUG repeat transcript (CUGexp) is the causative agent of myotonic dystrophy type 1 (DM1) by sequestering muscleblind-like 1 protein (MBNL1), a regulator of alternative splicing. On the basis of a ligand (1) that was previously reported to be active in an in vitro assay, we present the synthesis of a small library containing 10 dimeric ligands (4–13) that differ in length, composition, and attachment

  扩展的 CUG 重复转录本 (CUG exp ) 是通过隔离肌盲样 1 蛋白 (MBNL1) 导致 1 型强直性肌营养不良 (DM1) 的病原体，MBNL1 是可变剪接的调节因子。基于先前报道在体外测定中具有活性的配体 ( 1 )，我们提出了一个包含 10个二聚配体 ( 4-13 )的小文库的合成，这些配体的长度、组成和附着点不同链接链。与寡醚接头相比，寡氨基接头对 CUG RNA 的亲和力更大，并且更有效。最有效的体外配体（9) 被证明是水溶性的并且具有细胞和细胞核渗透性，在 DM1 细胞模型中显示 MBNL1 核糖核病灶几乎完全分散。使用延时共聚焦荧光显微镜观察到9的生物活性的直接证据是其在单个活 DM1 模型细胞中分散核糖核病灶的能力。
• Efficient Routes for the Synthesis of 1,4,7,10,13-Pentaazacyclohexadecane-14,16-dione

  日期：2007.3

  The synthetic access to 1,4,7,10,13-pentaazacyclohexadecane-14,16-dione was significantly improved from an overall yield of 1% to 33%. The procedure involved the use of COCF 3 or DDE as highly selective protecting groups for primary amines and of Boc to protect the secondary amine functions. The reaction of a tris-Boc protected tetraethylenepentamine with malonic acid gave the macrocycle in a 44% yield

  1,4,7,10,13-五氮杂环十六烷-14,16-二酮的合成获得率从1%的总收率显着提高到33%。该程序涉及使用 COCF 3 或 DDE 作为伯胺的高选择性保护基团和 Boc 以保护仲胺官能团。tris-Boc保护的四亚乙基五胺与丙二酸的反应产生44％产率的大环，然而与丙二酰氯的相同反应仅产生3.6％的所需产物。Boc 去保护和去除三氟乙酸盐得到最终产物 1,4,7,10,13-五氮杂环十六烷-14,16-二酮，总产率为 33%。

  Larger is better: Fas‐silencing siRNA can be delivered into the cytoplasm of human mesenchymal stem cells (hMSCs) by a bioreducible polymer (see picture). The enhanced anti‐apoptotic activity of the Fas‐silenced hMSCs means that they can be readily formulated as enlarged spheroids to significantly enhance angiogenic efficacy as compared to their smaller counterparts.

  越大越好：Fas 沉默 siRNA 可以通过生物可还原聚合物传递到人类间充质干细胞 (hMSC) 的细胞质中（见图）。Fas 沉默的 hMSC 增强的抗凋亡活性意味着它们可以很容易地配制成增大的球体，与较小的对应物相比，显着增强血管生成功效。
