这封信描述了基于ML297的持续的合成努力,ML297是一种有效、有效和选择性的GIRK1/2激活剂(∼是GIRK1/4的10倍,而在GIRK2/3上是无效的),通过迭代平行合成方法。对ML297中吡唑3-位的化学优化表明,不同官能化的3-环丙基在一系列1-(3-cyclopropyl-1-phenyl-1H-pyrazol-5-yl)ureas.中调节抑制剂/激活剂之间的GIRK药理重要的是,在吡唑核心的3-环丙基和N-苯基上都发现了将药理模式从抑制物调节为激活剂的新型分子开关,提供了第一个高选择性的GIRK1/2激活剂。
This Letter describes the on-going SAR efforts based on ML297, a potent, efficacious and selective GIRK1/2 activator (∼10-fold vs GIRK1/4 and inactive on GIRK2/3) via an iterative parallel synthesis approach. The chemical optimization at the 3-position of pyrazole within ML297 indicated that various functionalized 3-cyclopropyl moieties modulated GIRK pharmacology between inhibitor/activator within a series of 1-(3-cyclopropyl-1-phenyl-1H-pyrazol-5-yl)ureas. Importantly, novel ‘molecular switches’ that modulated the mode of pharmacology from inhibitor to activator was discovered on both the 3-cyclopropyl andN-phenyl moiety of the pyrazole core, providing the first highly selective GIRK1/2 activator.
