A series of derivatives of (phenylsulfanyl)benzoic acids bearing quinoline, 2,4-dihydroxy-3-propylacetophenone and 2,4-difluorobiphenyl moieties were prepared and their antileukotrienic activities evaluated. Some of the compounds were found to display multiple antileukotrienic effect in the inhibition of LTB4biosynthesis, binding to LTD4and LTB4receptors, superior to the standards (zileuton and zafirlukast) used. The compounds had an antiinflammatory effect, manifested with quinoline derivatives by a significant inhibition of bronchospasm induced by LTD4and/or albumin. The results of regression analysis correspond to the observation that the most active compounds belong to quinoline derivatives with the lowest lipophilicity. X-ray analysis of the quinoline compounds revealed that an intramolecular hydrophobic interaction of their aromatic rings does not occur in the solid state.
一系列带有喹啉、2,4-二羟基-3-丙基苯乙酮和2,4-二氟联苯基团的(苯基硫基)苯甲酸衍生物已经制备,并评估了它们的抗白三烯活性。发现其中一些化合物在抑制LTB4生物合成、结合到LTD4和LTB4受体方面显示出多重抗白三烯效应,优于所使用的标准物质(齐鲁通和扎非鲁卡斯特)。这些化合物具有抗炎作用,喹啉衍生物表现出通过显著抑制LTD4和/或白蛋白诱导的支气管痉挛来体现。回归分析的结果与观察结果相符,即最活性的化合物属于脂溶性最低的喹啉衍生物。喹啉化合物的X射线分析显示,它们的芳香环之间不存在固态中的分子内疏水相互作用。
