relationship of a novel series of isoquinoline CRTH2 antagonists bearing a methylene linker between the isoquinoline and benzamide moieties were described. Optimization focusing on the substituents of the benzamide portion in the right hand part of the molecule led to the identification of TASP0412098 (9l), which is a potent, selective CRTH2 antagonist (binding affinity: IC50=2.1 nM, functional activity:
描述了一系列新的异喹啉CRTH2拮抗剂的合成及其构效关系,该拮抗剂在异喹啉和苯甲酰胺部分之间带有亚甲基接头。着眼于分子右手部分的苯甲酰胺部分取代基的优化导致鉴定出TASP0412098(9l),这是一种有效的选择性CRTH2拮抗剂(结合亲和力:IC50 = 2.1 nM,功能活性:IC50 = 12 nM)。在小鼠和豚鼠中口服生物利用的化合物9l在豚鼠的支气管哮喘模型中口服给药后显示出体内功效。
