Structure-activity relationship study of β-oxidation resistant indole-based 5-oxo-6,8,11,14-eicosatetraenoic acid (5-oxo-ETE) receptor antagonists

5-Oxo-6,8,11,14-eicosatetraenoic acid (5-oxo-ETE) is formed from 5S-hydroxy-6,8,11,14-eicosatetraenoic acid (5-HETE) by the 5-lipoxygenase (5-LO) pathway under conditions associated with oxidative stress. 5-Oxo-ETE is an important pro-inflammatory mediator, which stimulates the migration of eosinophils via a 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 antagonists. Cyclopropyl and cyclobutyl substituents were well tolerated in this position, but were less potent as the highly active 3S-methyl compound. It seems likely that 3-alkyl substituents can affect the conformation of the 5-oxovalerate side chain containing the critical keto and carboxyl groups, thereby affecting interaction with the OXE-receptor.

Inhibition of 5-oxo-6,8,11,14-eicosatetraenoic acid-induced activation of neutrophils and eosinophils by novel indole oxe receptor antagonists

5-Oxo-6,8,11,14-eicosatetraenoic acid (5-oxo-ETE) is a 5-lipoxygenase product that is a potent granulocyte chemoattractant, which induces the infiltration of eosinophils into human skin when injected intradermally. It could therefore be an important proinflammatory mediator in eosinophilic diseases such as asthma and allergic rhinitis, and the OXE receptor, which mediates its actions, is therefore an attractive drug target. Using a structure-based approach in which substituents mimicking the essential polar (C1-C5) and hydrophobic (C15-C20) regions of 5-oxo-ETE were incorporated on an indole scaffold, we identified two potent selective OXE antagonists with IC50 values of about 30 nM. Neither compound displayed agonist activity and both inhibited 5-oxo-ETE-induced chemotaxis and actin polymerization and were relatively resistant to metabolism by rat liver homogenates. The active enantiomers of these racemic antagonists were even more potent, with IC50 values of 10 nM. These selective OXE antagonists could potentially be useful therapeutic agents in allergic diseases such as asthma.
