cysteinyl leukotriene cascade remains highly activated in some asthmatics, even those on high-dose inhaled or oral corticosteroids. Hence, inhibition of the leukotriene C4 synthase (LTC4S) enzyme could provide a new and differentiated core treatment for patients with a highly activated cysteinyl leukotriene cascade. Starting from a screening hit (3), a program to discover oral inhibitors of LTC4S led
虽然支气管扩张药和吸入性糖皮质激素是哮喘治疗的主要手段,但高达50%的哮喘患者仍未得到控制。许多研究表明,半胱氨酸白三烯级联反应在某些哮喘患者中仍保持高度活化,即使是在大剂量吸入或口服皮质类固醇药物中也是如此。因此,对白三烯C4合酶(LTC4S)酶的抑制作用可为高度激活的半胱氨酰白三烯级联反应的患者提供一种新的,差异化的核心治疗方法。从筛选命中(3)开始,发现LTC4S口服抑制剂的程序导致了(1S,2S)-2-(5-[(5-chloro-2,4-difluorophenyl)(2-fluoro-2-甲基丙基)氨基] -3-甲氧基吡嗪-2-基}羰基)环丙烷甲酸(AZD9898)(36),具有高亲脂性配体效率(LLE = 8.5)的皮摩尔LTC4S抑制剂(IC50 = 0.28 nM),口服给药后,在钙离子载体刺激的大鼠模型中,其在细胞(外周血单核细胞,IC50,游离= 6.2 nM)中表现
