  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.

• An Efficient Synthesis of a Multipotent Eicosanoid Pathway Modulator

  An efficient, scalable synthesis of the multipotent eicosanoid pathway modulator 2-[3-[3[[5-ethyl-4'-fluoro-2-hydroxyl[1,1'-bi-phenyl]-4-yl]oxy]-propoxy]2-propoxylphenoxy]benzoic acid (1) is described. The process consists of nine chemical steps with the longest linear sequence having six isolations. Palladium metal-mediated cross-coupling assembles the biaryl fragment, and selective S(N)Ar chemistry is used to construct the resorcinol fragment. The synthesis converges at a phenolic coupling with an alkyl chloride to give the core structure of the active pharmaceutical ingredient (API). Further elaborations of the core and salt formation provides the final API. This process produced the drug candidate in 41% overall yield at multikilogram scale.
