  用于气相色谱分析的烷基甘油脂标准品的合成：在嵌合体和鲨鱼肝油中的应用。

  摘要：

  天然 O-烷基甘油脂，也称为烷基醚脂质 (AEL)，具有通过醚键与甘油单元连接的长脂肪烷基链。AEL 普遍存在于不同的组织中，但在鲨鱼肝油、母乳、红细胞、血浆和骨髓中含量丰富。只有少数 AEL 是可商购的，而许多其他具有可变长度的饱和或单不饱和烷基链的 AEL 则无法获得。然而，这些化合物作为分析方法的标准是必要的。在这里，我们研究了不同的报道程序，并采用其中一些程序来制备一系列主要具有不同长度的饱和烷基链（14:0、16:0、17:0、19:0、 20:0、22:0）和两个单不饱和链（16:1、18:1）。所有这些标准品均通过 NMR 和 GC-MS 进行了全面表征。最后，我们使用这些标准来鉴定鲨鱼和嵌合体肝油中的 AEL 亚型。已确定的 AEL 分布为：14:0 (20-24%)、16:0 (42-54%) 和 18:1 (6-16%)，以及较小程度的 (0.2-2%)对于以下各项：16:1、17:0、18:0

• Synthesis of Lipid-Oligonucleotide Conjugates for RNA Interference Studies

  DOI：10.1002/cbdv.201000274

  日期：2011.2

  The synthesis of RNA molecules carrying lipids at their 3′‐termini and 5′‐termini is reported. These conjugates were fully characterized by MALDI‐TOF mass spectrometry and HPLC chromatography. The ability of these conjugates to silence gene expression was evaluated in the inhibition of the tumor necrosis factor. All the lipidsiRNA derivatives were compatible with RNA interference machinery if transfected

• Sterol-Modified Phospholipids: Cholesterol and Phospholipid Chimeras with Improved Biomembrane Properties
  作者：Zhaohua Huang、Francis C. Szoka

  DOI：10.1021/ja8065557

  日期：2008.11.19

  We synthesized a family of sterol-modified glycerophospholipids (SML) in which the sn-1 or sn-2 position is covalently attached to cholesterol and the alternative position contains an aliphatic chain. The SML were used to explore how anchoring cholesterol to a phospholipid affects cholesterol behavior in a bilayer. Notably, cholesterol in the SML retains the membrane condensing properties of free cholesterol regardless of the chemistry or position of its attachment to the glycerol moiety of the phospholipid. SMLs by themselves formed liposomes upon hydration and in mixtures between an SML and diacylglycerophospholipids (C14 to C18 chain length) the thermotropic phase transition is eliminated at the SML equivalent of about 30 mol % free cholesterol. Osmotic-induced contents leakage from SML (C14-C18) liposomes depends upon the linkage and position of cholesterol but in general is similar to that observed in 3/2 diacylphosphatidylcholine/cholesterol (mole ratio) liposomes. SML liposomes are exceptionally resistant to contents release in the presence of serum at 37 degrees C. This is probably due to the fact that SML exchange between bilayers is more than 100 fold less than the exchange rate of free cholesterol in the same conditions. Importantly, SML liposomes containing doxorubicin are as effective in treating the murine C26 colon carcinoma as Doxil, a commercial liposome doxorubicin formulation. SMLs stabilize bilayers but do not exchange and hence provide a new tool for biophysical studies on membranes. They may improve liposomal drug delivery in organs predisposed to the extraction of free cholesterol from bilayers, such as the skin, lung, or blood.
• Nucleoside Conjugates. 14. Synthesis and Antitumor Activity of 1-.beta.-D-Arabinofuranosylcytosine Conjugates of Ether Lipids with Improved Water Solubility

  A series of ara-CDP-rac-1-O-alkyl-2-O-acylglycerol (9a-f), analogues of highly active ara-CDP-rac-1-O-hexadecyl-2-O-palmitoylglycerol (1) and Cytoros(2) (2), was prepared, and solubility, lipophilicity, and structure-activity relationships of these conjugates were investigated. Conjugates 9a-f containing sn-1 alkyl (C-16) and the sn-2 fatty acyl (>C-16) such as conjugate 1 were sparingly soluble. Conjugates 9a-c,e were almost completely solubilized in water by shaking. However, a large portion of conjugates 9d and 9f in water by shaking exist in micelles with mean diameters ranging 7.0-55.2 nm. The partition coefficients (1-octanol/PBS) of the water-soluble conjugates were about 9-18 times greater than that of ara-C. A single dose (300 mg/kg) of conjugates 9d and 9f produced a significant increase in life span (ILS 206 to >543%) with 17-67% long-term survivors (>45 days) in mice bearing ip-implanted L1210 lymphoid leukemia. These results were comparable to those of the previous conjugate 1 and Cytoros (2). In contrast, conjugates 9a-c,e at single doses were less effective (ILS 69-178% with no long-term survivors). However, two (qd, 1, 7) or three (qd 1, 5, 9) divided doses of these conjugates were found to be as effective as a single dose of the previous conjugates. The three divided doses (150 mg/kg per day) of conjugates 9d, 9e, and 9f produced a remarkable antitumor activity in L1210 leukemic mice (ILS >350% with >50% long-term survivors). Because of the convenient formulation and the significant antitumor activities, the water-soluble conjugates 9d, 9e, and 9f warrant further investigation.
