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

  摘要：

  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。

  Sphingosine-1-phosphate (S1P) influences various fundamental biological processes by interacting with a family of five G protein-coupled receptors (S1P(1-5)). FTY720, a sphingosine analogue, which was approved for treatment of relapsing forms of multiple sclerosis, is phosphorylated in vivo and acts as an agonist of four of the five S1P receptor subtypes. Starting from these lead structures we developed new agonists for the S1P(1) receptor. The biological activity was tested in vivo and promising ligands were fluorinated at different positions to identify candidates for positron emission tomography (PET) imaging after [F-18]-labelling. The radioligands shall enable the imaging of S1P(1) receptor expression in vivo and thus may serve as novel imaging markers of S1P-related diseases. (C) 2015 Elsevier Ltd. All rights reserved.

  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.
