selective G-protein coupled receptor, known as the OXE receptor (OXE-R). Previously, we designed and synthesized structural mimics of 5-oxo-ETE such as 1 using an indole scaffold. In the present work, we added various substituents at C-3 of this moiety to block potential β-oxidation of the 5-oxo-valerate side chain, and investigated the structure-activity relationships of the resulting novel β-oxidation-resistant
5-Oxo-6,8,11,14-二十碳四烯酸(5-oxo-ETE)由5 S-羟基-6,8,11,14-二十碳四烯酸(5-HETE)通过5-脂氧合酶( 5-LO)途径在与氧化应激相关的条件下。5-Oxo-ETE是重要的促炎介质,它通过选择性的G蛋白偶联受体OXE受体(OXE-R)刺激嗜酸性粒细胞的迁移。以前,我们设计并合成了5-oxo-ETE的结构模拟物,例如1使用吲哚支架。在目前的工作中,我们在该部分的C-3处添加了各种取代基,以阻断5-氧代戊酸酯侧链的潜在β-氧化,并研究了所得新型β-抗氧化拮抗剂的结构-活性关系。环丙基和环丁基取代基在该位置具有良好的耐受性,但作为高活性3 S-甲基化合物的效力较低。3-烷基取代基似乎可以影响含有关键的酮基和羧基的5-氧戊酸侧链的构象,从而影响与OXE-受体的相互作用。
