  摘要：

  通过烯烃交叉复分解反应的两种组合，建立了一种高效且通用的合成各种鞘脂的方法，如鞘磷脂，神经酰胺，鞘氨醇，1-磷酸鞘氨醇和功能化鞘氨醇衍生物。一个反应是在相同的烯烃部分与合适的氨基醇之间，它们从N-Boc-L-丝氨酸开始制备，另一个反应在合适的烯烃与相同的氨基醇之间。[反应：请参见文字]。

  A highly stereoselective synthesis of (E)-alkene dipeptide isosteres via organocyanocopper-Lewis acid mediation reaction

  摘要：

  A stereoselective synthesis of protected (E)-alkene dipeptide isosteres by the reaction of the mesylates of homochiral delta-aminated gamma-hydroxy (E)-alpha,beta-enoates with either RCu(CN)Li.BF3 or RCu(CN)MgX.BF3 reagent is described. The degree of diastereoselectivity has been found to be uniformly high except for the serine- and threonine-derived acetonides 77 and 81. The synthesis permits the introduction of sterically hindered appendages such as isopropyl and tert-butyl groups at the alpha position to the ester group. This methodology provides a new route to a wide range of modified (E)-alkene peptide mimics that may have biological importance.

• Exploring Leishmania major Inositol Phosphorylceramide Synthase (LmjIPCS): Insights into the ceramide binding domain

  The synthesis of set of ceramide analogues exploring hydrophobicity in the acyl chains and the degree and nature of hydroxylation is described. These have been assayed against the parasitic protozoan enzymeLmjIPCS. These studies showed that whilst the C-3 hydroxyl group was not essential for turnover it provided enhanced affinity. Reflecting the membrane bound nature of the enzyme a long (C13) hydrocarbon ceramide tail was necessary for both high affinity and turnover. Whilst the N-acyl chain also contributed to affinity, analogues lacking the amide linkage functioned as competitive inhibitors in both enzyme and cell-based assays. A model that accounts for this observation is proposed.

  本文描述了一组神经酰胺类似物的合成，这些类似物探讨了酰基链的疏水性、羟基化的程度和性质。它们已被用于检测寄生原生动物酶LmjIPCS。这些研究表明，尽管C-3羟基团对酶的代谢转化不是必需的，但它提供了增强的亲和力。鉴于该酶的膜结合性质，需要一个长（C13）碳氢神经酰胺尾部以实现高亲和力和代谢转化。虽然N-酰基链也对亲和力有所贡献，但缺乏酰胺键连接的类似物在酶和细胞基础测试中作为竞争性抑制剂发挥了作用。针对这一观察结果，我们提出了一个理论模型。
