    摘要:
    内体区室和局部缺血组织的低pH环境特征提供了一条内在的途径,可触发从特定设计的载体中释放特定部位的内含物。因此,该组的研究集中在新型酸敏感脂质的设计,合成和应用上,这些脂质将在这些酸性位点内经历容易的层状(L alpha)到六角形(HII)相变。以前,已经证明血浆胆碱型脂质具有优异的酸水解和内容物释放动力学(Gerasimov等,Biochim.Biophys.Acta.1324(1997)200-214; Rui等,J.Am.Chem。 Soc.120(1998)11213-11218)。本文描述了基于手性1,2-di-O-(1Z',9Z'-十八碳二烯基)-sn-甘油(6)平台的三种新的酸敏感性脂质的合成,显示磷胆碱(7),聚环氧乙烷(8)和O-氨基甲酰基-N-二乙烯-三胺(10)头基。通过六步合成,由(S)-(+)-2,2-二甲基-1,2-二氧戊环-4-甲醇以中间体的总产率28%获得中

  • Base-Pairing Properties of a Structural Isomer of Glycerol Nucleic Acid
    作者:Phaneendrasai Karri、Venkateshwarlu Punna、Keunsoo Kim、Ramanarayanan Krishnamurthy
    DOI:10.1002/anie.201300795
    日期:2013.5.27
    limit! IsoGNA (a structural isomer of GNA) was found—in sharp contrast to GNA—to be highly restricted in its ability to basepair with itself and other nucleic acids. While homogeneous sequences (e.g. isoGNA(A)16) formed duplexes, the heterogeneous sequences showed no basepairing. This exemplifies the limitations of canonical nucleobases as the recognition elements in simpler, more primitive phosphate
    知道你的极限!与GNA形成鲜明对比的是,发现IsoGNA(GNA的结构异构体)在与自身和其他核酸碱基配对的能力上受到严格限制。虽然同质序列(例如isoGNA(A)16)形成双链体,但异质序列未显示碱基配对。这举例说明了在更简单,更原始的磷酸盐骨架中作为识别元件的规范核碱基的局限性。

    IsoGNA, an isomer of glycerol nucleic acid GNA, is a flexible (acyclic) nucleic acid with bases directly attached to its linear backbone. IsoGNA exhibits (limited) base-pairing properties which are unique compared to other known flexible nucleic acids. Herein, we report on the details of the preparation of isoGNA phosphoramidites and an alternative route for the synthesis of the adenine derivative. The synthetic improvements described here enable an easy access to isoGNA and allows for the further exploration of this structural unit in oligonucleotide chemistry thereby spurring investigations of its usefulness and applicability.

    IsoGNA,甘油核酸GNA的异构体,是一种灵活(非环状)的核酸,其碱基直接连接到其线性骨架上。与其他已知的灵活核酸相比,IsoGNA表现出(有限的)碱基配对特性。在这里,我们报告了IsoGNA酰胺酯的制备细节以及腺嘌呤生物合成的另一种途径。这里描述的合成改进使得易于获得IsoGNA,并允许进一步探索这种结构单元在寡核苷酸化学中的应用,从而推动对其有用性和适用性的研究。
  • Synthesis of L-Dioxolane Nucleosides and Related Chemistry

    (+)-L- or (+)-(2R,4S)-1-[4-(hydroxymethyl)-1,3-dioxolan-2-yl]-5-fluorouracil (25) and other novel classes of 1,3-dioxolane nucleosides have been synthesized. Coupling of 2-methoxy-4-[[(tert-butyldiphenylsilyl)oxy]methyl]-1,3-dioxolane (23) or 2-methyl-1,3-dioxolane (9) with silylated g-fluorouracil, thymine, cytosine, and 5-chlorocytosine in the presence of TMSOTf gave the corresponding 1,3-dioxolane nucleosides. These nucleosides were decomposed and rearranged to the ring-opened products in certain reaction conditions. It was found that 5-fluorouricil nucleosides (12 and 25) were relatively more stable than the thymine or cytosine derivatives (10, 13, and 16). Bulky protecting group (TBDPS) at the 1,3-dioxolane moiety in compound 24 may also contribute the stability to the 1,3-dioxolane nucleosides. The structures of these novel 1,3-dioxolane nucleosides and ring-opened products have been assigned by NMR spectra, and the mechanisms of decomposition and rearrangement to the ring opened products were discussed.

  • A Facile Synthesis of (<i>S</i>)-3-Tosyloxy-1,2-propanediol from (<i>S</i>)-2,2-Dimethyl-1,3-dioxolane-4-methanol
    作者:Katerina Leftheris、Murray Goodman
    DOI:10.1055/s-1989-27322
    日期:——
    (S)-3-Tosyloxy-1,2-propanediol[(S)-2] has been synthesized from (S)-2,2-dimethyl-1,3-dioxolane-4-methanol [(S)-1] in four steps with an overall yield of 87%. This coupled with the existing method in the literature for the conversion of (S)-1 to (R)-2 allows both (R)- and (S)-2 to be readily available from either (S)- or (R)-1. The use of the tert-butyldiphenylsilyl protecting group permits two acid labile protecting groups to be incorporated simultaneously. Selective reactions and deprotections lead to the desired configuration.
    (S)-3-Tosyloxy-1,2-propanediol[(S)-2] 是由 (S)-2,2-二甲基-1,3-二氧戊环-4-甲醇 [(S)-1] 经过四个步骤合成的,总收率为 87%。这与文献中现有的将(S)-1 转化为(R)-2 的方法相结合,使得(R)-和(S)-2 都可以很容易地从(S)-或(R)-1 中获得。使用叔丁基二苯基硅烷保护基团可以同时加入两个酸性保护基团。通过选择性反应和脱保护作用可以得到所需的构型。
