hydrophilic secondary binding group, served as an initiation point. A more hydrophobic set of secondary binding groups was explored, prepared rapidly from a common intermediate by Buchwald–Hartwig amination. TD-5471 (25), a potent and selective full agonist of the human β2-adrenoceptor, was identified as the most promising agent. It is potent, with slow onset in an in vitro guinea pig trachea model
一系列有效的β的2结合有二芳基胺的第二结合基肾上腺素能受体兴奋剂被确定。先前报道米维特罗(5)中,由多价的方法和含有典型β识别2激动剂主要结合经由苯乙胺接头连接到亲水性的第二结合基团,任一个起始点。探索了更多的疏水性二级结合基团,由布赫瓦尔德-哈特维希胺化从普通中间体快速制备。TD-5471(25),人的有效和选择性完全激动剂β 2-肾上腺素受体,被确定为最有希望的药物。它是有效的,在体外豚鼠气管模型中起效缓慢,并且在体内豚鼠支气管保护模型中显示出剂量依赖性和长效作用。TD-5471在结构上米维特罗分化和它的长作用持续时间是与其他长效β观察到疏水性的相关性一致的2 -激动剂的发现程序。
