  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.

  [3H] LTB4 binding to human neutrophils, and by a secondary intact human neutrophil functional assay for agonist/antagonist activity. The first analogues prepared, compounds 2-7, demonstrated moderate potency in the LTB4 receptor binding assay. The modification of these compounds by the introduction of another substituent into the aromatic ring produced a marked increase in receptor binding (28c, IC50

  白三烯B4（LTB4）的结构类似物是根据LTB4的合理构象设计的（1）。将构象体A或B的C-7-C-9连接到芳香环系统中，导致发现苯类似物2、4和6a。将构象体C或D的C-4-C-9连接到芳香环系统中，导致发现类似物3、5和7。评估了本研究中化合物对[3H] LTB4结合的抑制作用人类嗜中性粒细胞，并通过第二次完整的人类嗜中性粒细胞功能测定来确定激动剂/拮抗剂活性。制备的第一个类似物化合物2-7在LTB4受体结合试验中显示出中等效力。通过将另一个取代基引入芳环对这些化合物进行修饰，可显着提高受体结合力（28c，IC50 = 0.020 microM; 38c，IC50 = 0。020微米; 52a，IC 50 ＝0.020μM；52b，IC 50 ＝0.018μM。LTB4的大多数这些结构类似物表现出激动剂活性。在这项研究中制备的类似物中，只有化合物57在10 microM时显示出弱的LTB4受体拮抗剂活性。
