  The design and synthesis of a 5-HETE affinity chromatography ligand for 5-hydroxyeicosanoid dehydrogenase

  摘要：

  The first total synthesis of an omega-amino 5-HETE derivative 27 has been accomplished by a new counterclockwise strategy, in which C-1 is constructed first and C-20 last. The omega-amino 5-HETE derivative was transformed to an affinity chromatography ligand, the biotinylated 5-HETE 30. This affinity chromatography ligand is aimed at purifying the 5-hydroxyeicosanoid dehydrogenase enzyme, which is responsible for the conversion of 5-HETE to 5-oxo-ETE, a potent eosinophil chemotactic factor.

  C20-trifluoro-5-oxo-ETE: A metabolically stable 5-oxo-ETE derivative

  摘要：

  The total synthesis of C-20-trifluoro-6(E),8(Z),11(Z),14(Z) 5-oxo-ETE is reported. This compound was designed as an x-oxidation-resistant analog of 5-oxo-ETE that would be resistant to metabolism. The trifluoro derivative of 5-oxo-ETE stimulated calcium mobilization in neutrophils and desensitized these cells to subsequent exposure to 5-oxo-ETE. (C) 2011 Elsevier Ltd. All rights reserved.

  Our main goal is to determine how the biosynthesis of 5-oxo-ETE is regulated and to determine its pathophysiological roles. To achieve this task, we designed and synthesized affinity chromatography ligands for the purification of 5-hydroxyeicosanoid dehydrogenase (5-HEDH), the enzyme responsible for the formation of 5-oxo-ETE.

  花生四烯酸（AA）通过不同的途径转化为具有生物活性的代谢物，其中最重要的途径之一是由5-脂氧合酶（5-LO）引发的。5-羟基己二酸四氢呋喃酸（5-HETE）本身仅具有较弱的生物活性，但会被氧化为5-氧代-6,8,11,14-二十碳四烯酸（5-oxo-ETE），对嗜酸性粒细胞和嗜中性粒细胞有很强的化学吸引力。 。我们的主要目标是确定如何调节5-oxo-ETE的生物合成并确定其病理生理作用。为实现此任务，我们设计并合成了亲和色谱配体，用于纯化5-羟基二十烷酸脱氢酶（5-HEDH），该酶负责形成5-oxo-ETE。

  The design and synthesis of a photoaffinity ligand 26, targeted at the 5h-dh, was accomplished. The synthesis was effected by two new synthetic routes which focus on the omega-hydroxy 5-HETE derivative 12 as a pivotal synthon. Preliminary results show ligand 26 to be an excellent substrate for the 5h-dh. (C) 2000 Elsevier Science Ltd. All rights reserved.
