S1P1 agonists. We have recently disclosed a series of orally active tetrahydroisoquinoline (THIQ) compounds matching these criteria. In this paper we describe how we defined and implemented a strategy aiming at the discovery of selective structurally distinct follow-up agonists. This effort culminated with the identification of a series of orally active tetrahydropyrazolopyridines.
FTY720是第一个批准用于治疗复发缓解型多发性硬化症患者的口服小分子药物。它是S1P 1受体的有效激动剂,但对S1P 3受体的选择性缺乏与临床中观察到的大多数心血管副作用有关。这些发现引发了为识别第二代S1P 3 -S1P 1而付出的巨大努力。激动剂。我们最近公开了一系列符合这些标准的口服活性四氢异喹啉(THIQ)化合物。在本文中,我们描述了我们如何定义和实施旨在发现选择性结构不同的后续激动剂的策略。这项努力最终鉴定出一系列口服活性四氢吡唑并吡啶。
