  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.

  The invention relates to the use of an inhibitor of the biosynthesis and/or function of LTB 4 for the manufacture of a medicament for the treatment of B-cell chronic lymphocytic leukemia (B-CLL), B-prolymphocytic leukemia (B-PLL) or B-cell lymphoma. Preferably, the inhibitor of the biosynthesis and/or function of LTB 4 is the inhibitor of 5-LO BWA4C or the inhibitor of FLAP MK-886.
