  摘要：

  已合成十六种手性C4-环氧化物 [(-)-10a-d, (+)-10a-d, (-)-11a-d, (+)-11a-d]，这些化合物是我们合成复杂脂质策略中的合成子，通过使用Sharpless不对称环氧化反应，从(2Z)-2-丁烯-1, 4-二醇(6)制备而成。利用手性C4-环氧化物 [(+)-10a, (-)-10a, (-)-11a, (+)-11a] 作为起始化合物，通过环氧环的区域选择性开环反应与叠氮阴离子结合，随后将叠氮基团还原为氨基，并进行Wittig反应，合成了两对对映异构体（D-赤藓糖，L-赤藓糖，D-反式，L-反式）C18-鞘氨醇（1, 2, 3, 4）。此外，D-赤藓糖-C18-鞘氨醇（1）通过与棕榈酸和D-葡萄糖的连续缩合反应途径转化为高雪氏脾脏葡萄糖苷脂（5）的棕榈酰类似物（5a）。

• Stereoselective synthesis of trans-olefins by the copper-mediated SN2′ reaction of vinyl oxazines with Grignard reagents. Asymmetric synthesis of d-threo-sphingosines
  作者：Om V. Singh、Hyunsoo Han

  日期：2007.3

  The S(N)2' reaction of 6-vinyl-5,6-dihydro-4H-[1,3]oxazines with Grignard reagents in the presence of CuCN was studied, and high trans selectivity for the formation of double bond was observed with a variety of RMgX. The S(N)2' reaction, coupled with regioselective asymmetric aminohydroxylation reaction, provided a highly efficient route for the asymmetric synthesis of D-threo-N-acetylsphingosine.

  Enantiomers or diastereomers of chiral bioactive compounds often exhibit different biological and toxicological properties. Here, we report the efficient synthesis of four stereoisomers of sphingosine and derivatization of unique chiral ceramides through a combinatorial chemistry by solid‐phase activated resin ester. In addition, to test the effectivity of stereochemistry of ceramide, we demonstrated

• Inhibitory activity of a ceramide library on interleukin-4 production from activated T cells

  Allergic diseases are hypersensitivity disorders associated with the production of specific immunoglobulin E (IgE) to environmental allergens. Interleukin (IL)-4, produced primarily by CD4(+) T cells, is an important stimulus for the switch of the antibody isotype to IgE in both mice and humans. In this study we investigated the inhibitory activity of IL-4 production in activated T cells by screening ceramide derivatives prepared by solid phase combinatorial chemistry. Many ceramide derivatives significantly inhibited IL-4 production in T cells. In particular, ceramide derivatives with a lauroyl group showed strong inhibitory activities on IL-4 production in both phorbol 12-myristate 13-acetate (PMA)-activated EL4 T cells and antigen-primed cells, suggesting that they can be used as compounds for the development of anti-allergic agents.

  A facile synthesis of a combinatorial ceramide library and their activities in the NF-kappaB pathway and in apoptosis induction/prevention were demonstrated. A novel NF-kappaB activating molecule was discovered among ceramide containing beta-galactose, and the structural requirements of ceramides for apoptosis induction was elucidated.
