  Straightforward Access to Spisulosine and 4,5-Dehydrospisulosine Stereoisomers: Probes for Profiling Ceramide Synthase Activities in Intact Cells

  摘要：

  A stereoselective synthesis of spisulosine (ES285) and 4,5-dehydrospisulosine stereoisomers is described. Hydrozirconation of 1-pentadecyne with Schwartz reagent, followed by diastereocontrolled addition to L- or D-alaninal afforded the required 2-amino-1,3-diol framework. The resulting sphingoid bases revealed as excellent probes for the profiling of ceramide synthase activity in intact cells. Among the sphingoid bases described in this work, spisulosine (ES285), RBM1-77, and RBM1-73 were the most suitable ones because of their highest acylation rates. These molecules should prove useful to study the role of the different ceramide synthases and the resulting N-acyl (dihydro)ceramides in cell fate.

  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。
