  Synthetic and Structure/Activity Studies on Acid-Substituted 2-Arylphenols: Discovery of 2-[2-Propyl-3-[3-[2-ethyl-4-(4-fluorophenyl)-5-hydroxyphenoxy]- propoxy]phenoxy]benzoic Acid, a High-Affinity Leukotriene B4 Receptor Antagonist

  摘要：

  Structural derivatives of LY255283 have been studied as receptor antagonists of leukotriene B-4. Substitution of the 2-hydroxyacetophenone subunit of 1 (LY255283) with a 2-arylphenol group provided entry into several new series that feature various mono- and diacidic core functionality. These new analogues, the subject of a broad structure-activity investigation, displayed significantly increased in vitro and in vivo activity as receptor antagonists of LTB(4). A series of diaryl ether carboxylic acids demonstrated especially interesting activity and led to the discovery of compound 43b, 2-[2-propyl-3-[3-[2-ethyl-4-(4-fluorophenyl)-5-hydroxyphenoxy]- propoxy]phenoxy]benzoic acid (LY293111), a 2-arylphenol-substituted diaryl ether carboxylic acid which displayed potent binding to human neutrophils (IC50 = 17 +/- 14.6 nM) and guinea pig lung membranes (IC50 6.6 +/- 0.71 nM), inhibition of LTB(4)-induced expression of the CD11b/CD18 receptor on human neutrophils (IC50 - 3.3 +/- 0.81 nM), and inhibition of LTB(4)-induced contraction of guinea pig lung parenchyma (pK(B) = 8.7 +/- 0.16). In vivo, 43b demonstrated potent activity in inhibiting LTB(4)-induced airway obstruction in the guinea pig when dosed by the oral (ED(50) = 0.40 mg/kg) or intravenous (ED(50) = 0.014 mg/kg) routes. A specific LTB(4) receptor antagonist, 43b had little effect on inhibiting contractions of guinea pig lung parenchyma induced by leukotriene D-4 (LTD(4)), histamine, carbachol, or U46619. Compound 43b has been chosen as a clinical candidate and is currently in phase I studies for a variety of inflammatory diseases.

  expedient and general strategy for the ortho-arylation of phenols and naphthols using readily available boronic acids. Our methodology relies on in situ generation of a uniquely reactive Bi(V) arylating agent from a bench-stable Bi(III) precursor via telescoped B-to-Bi transmetallation and oxidation. By exploiting reactivity that is orthogonal to conventional metal-catalysed manifolds, diverse aryl and heteroaryl

  鉴于 2-羟基联芳基化合物在有机化学、药物化学和材料化学中的重要作用，合成这种常见基序的简明方法非常有价值。在寻求扩展合成化学家在这方面的词典时，我们开发了一种使用现成的硼酸对苯酚和萘酚进行邻位芳基化的权宜之计和通用策略。我们的方法依赖于通过伸缩的 B 到 Bi 转金属和氧化从工作台稳定的 Bi(III) 前体原位生成独特的反应性 Bi(V) 芳基化剂。通过利用与传统金属催化歧管正交的反应性，多种芳基和杂芳基伙伴可以在温和条件下与苯酚和萘酚快速偶联。芳基化后，Bi（III）前体的高产率回收允许其在后续反应中有效地重复使用。对该方法的每个关键步骤的机械询问为其实际应用提供了信息，并提供了对有机铋化合物未充分利用的反应性的基本见解。
