Piriqualone (1) was found to be an antagonist of AMPA receptors. Structure activity optimization was conducted on each of the three rings in 1 to afford a series of potent and selective antagonists. The sterically crowded environment surrounding the N-3 aryl group provided sufficient thermal stability for atropisomers to be isolated. Separation of these atropisomers resulted in the identification of
Piriqualone(1)被发现是AMPA受体的拮抗剂。对三个环中的每一个进行结构活性优化,以提供一系列有效和选择性的拮抗剂。N-3芳基周围的空间拥挤环境为要分离的阻转异构体提供了足够的热稳定性。这些阻转异构体的分离导致鉴定出(+)-38(CP-465,022),该化合物以高亲和力(IC50 = 36 nM)与AMPA受体结合并显示出有效的抗惊厥活性。
