optimization, and evaluation of a series of novel imidazopyridazine-based subtype-selective positive allosteric modulators (PAMs) for the GABAA ligand-gated ion channel are described. From a set of initial hits multiple subseries were designed and evaluated based on binding affinity and functional activity. As designing in the desired level of functional selectivity proved difficult, a probability-based
GABAA配体门控离子通道的一系列新型咪唑并哒嗪基亚型选择性正变构调节剂(PAM)的设计,优化和评估。从一组初始命中物中,设计了多个亚系列,并根据结合亲和力和功能活性对其进行了评估。由于难以在所需的功能选择性水平上进行设计,因此进行了基于概率的评估,以将项目的工作重点放在单个子系列上,该子系列提供目标配置文件的可能性最大。这些努力最终导致从该亚系列中鉴定出两个候选物,这些候选物已进行到临床前安全性研究,随后又鉴定了临床候选物PF-06372865。
