specific leukotriene B4 (LTB4) receptor antagonists, several xanthone dicarboxylic acids were synthesized and evaluated. Two separate synthetic routes were used to construct a xanthone nucleus containing a regiospecific orientation of each carboxylic acid pharmacophore. These compounds represent the major conformationally-restricted analogues of benzophenone dicarboxylic acids previously shown to antagonize
为了开发越来越有效的特异性白三烯B4(LTB4)受体拮抗剂,合成并评估了几种x吨酮二羧酸。使用两种单独的合成途径来构建包含每种羧酸药效基团的区域特异性取向的x吨酮核。这些化合物代表了苯甲酮二羧酸的主要构象受限的类似物,先前已证明可拮抗LTB4对人嗜中性粒细胞的活化作用。最有效的药物是化合物32,它可抑制[3H] LTB4与完整人类嗜中性粒细胞(IC50,6.2 +/- 0.1 nM),LTB4诱导的鲁米诺依赖性化学发光(IC50,55 +/- 11)上的受体的特异性结合。 nM),聚集(IC50,133 +/- 42 nM)和趋化性(IC50,899 +/- 176 nM)。该化合物是N-甲酰基-L-甲硫酰基-L-亮氨酰-L-苯丙氨酸诱导的化学发光(IC50,1599 +/- 317 nM)和聚集(IC50,2166 +/- 432 nM)的弱拮抗剂。在抑制LTB4刺激的事件中。完全没有激
