challenge in actively sensitized guinea pigs, 47.Na dosed orally blocked bronchoconstriction with an ED(50) = 0.4 mg/kg, the most potent activity we have observed for any leukotriene inhibitor in this model. The mode of inhibitory action of 47.Na occurs at the stage of 5-lipoxygenase biosynthesis as it blocks both leukotriene pathways leading to LTB(4) and LTC(4) but not PGH(2) biosynthesis. However,
对对称的双(喹啉基甲氧基苯基)烷基羧酸作为白三烯生物合成的抑制剂进行了研究,并且4,4-双(4-(2-(喹啉基甲氧基)苯基)戊酸钠盐(47.Na)达到了我们针对候选药物(ABT- 080)。该化合物易于从市售的二酚酸分三步合成。针对完整的人类中性粒细胞,Na.47抑制离子载体刺激的LTB(4)形成,IC(50)= 20 nM。在酵母聚糖刺激的小鼠腹膜巨噬细胞中产生LTC(4)和PGE(2)的47.Na抑制LTC(4)(IC(50)= 0.16 nM)的选择性是PGE(2)的9000倍(IC (50)= 1500 nM)。在大鼠和食蟹猴中的初步药代动力学评估表明,口服生物利用度良好,消除半衰期分别为9 h和5 h。在大鼠胸膜炎症模型(ED(50)= 3 mg / kg)和大鼠腹膜被动过敏模型(LTB(4),ED(50)= 2.5 mg / kg)中证明了口服白三烯的药理学评价。 LTE(4),ED(50)=
