competitive antagonists of the CP101-606 binding site within the NR2B subtype of the NMDA receptor. The compounds identified do not possess phenolic functional groups such as those in ifenprodil and related analogs. Initial identification of hits in this series focused on a basic, secondary amine side chain which led to good potency, but also presented a hERG liability. Further modifications led to examples
本文中,我们描述了化合物的发现,该化合物是NMDA受体NR2B亚型内CP101-606结合位点的竞争性拮抗剂。鉴定出的化合物不具有酚类官能团,如艾芬地尔和相关类似物中的那些。该系列中命中的初步鉴定集中在碱性,仲胺侧链上,这导致了良好的效能,但同时也表现出hERG责任。进一步的修改导致出现了一些非基本替换的例子,这些例子在这方面的责任要小得多。最后,在小鼠强迫游泳抑制试验中测试了系列6a中的一种化合物,发现其具有活性(sc 60 mg / kg)。
