  Synthesis and Structure−Activity Relationships of New 1,3-Disubstituted Cyclohexanes as Structurally Rigid Leukotriene B₄ Receptor Antagonists

  摘要：

  A series of 1-hydroxy-3-[3-hydroxy-7-phenyl-1-hepten-1-yl] cyclohexane acetic acid derivatives was designed based on postulated active conformation of leukotriene B-4 (LTB4) and evaluated as human cell surface LTB4 receptor (BLTR) antagonists. Binding was determined through [H-3]LTB4 displacement from human neutrophils and receptor antagonistic assays by in vitro measurements of inhibition of leukocyte chemotaxis induced by LTB4. On the basis of these assays, a structure-affinity relationship was investigated. Optimization of the acid chain length and omega-substitution of a phenyl group on the lipophilic tail were shown to be critical for binding activity. These modifications led to the discovery of compounds with submicromolar potency and selective BLTR antagonism. The most potent compound 3b alpha (IC50 = 250 nM) was found to significantly inhibit oedema formation in a topical model of phorbolester-induced inflammation. Substantial improvement of in vitro potency was achieved by modification of the carboxylic acid function leading to the identification of the N,N-dimethylamide series. Compound 5b alpha, free of agonist activity, displayed higher potency in receptor binding with an IC50 of 40 nM. These results support the hypothesis that the spatial relationship between the carboxylic acid and allylic hydroxyl functions is crucial for high binding affinity with BLTR.

  Synthesis and pharmacological profile of new 1,3-disubstituted cyclohexanes as leukotriene B4 receptor antagonists

  摘要：

  In the course of developing stable leukotriene B-4 antagonists, we synthesized a novel non aromatic series of compounds containing a 1, 3-disubstituted cyclohexane ring in place of the conjugated double bonds of the natural eicosanoid. The Structure-Activity Relationship (SAR) studies leading to the identification of the acid <(1d)under bar> are described. Copyright (C) 1996 Elsevier Science Ltd
