Based on previous work that established fused heterocycles as viable alternatives for the picolinamide core of our lead series of mGlu5 negative allosteric modulators (NAMs), we designed a novel series of 6-(pyrimidin-5-ylmethyl)quinoline-8-carboxamide mGlu5 NAMs. These new quinoline derivatives also contained carbon linkers as replacements for the diaryl ether oxygen atom common to our previously
基于以前的工作,在我们的mGlu 5负变构调节剂(NAMs)铅系列中将稠合杂环确定为吡啶啉核心的可行替代品,我们设计了一系列新颖的6-(嘧啶-5-基甲基)喹啉-8-羧酰胺mGlu。5个NAM。这些新的喹啉衍生物还含有碳连接基,以取代我们以前发表的化学型通用的二芳基醚氧原子。化合物在基于细胞的功能性mGlu 5分析中进行了评估,并使用了类似的类似物27相对于其他七个mGlu受体,其选择性> 60倍。还在大鼠和人S9肝组分的代谢稳定性测定中研究了所选化合物,并显示了P450和非P450介导的代谢的混合物。
