AbstractA series of substituted imidazoquinolines, a structurally related chemotype to pyrazoloquinolinones, a well-known class of GABAA ligands, was prepared via two synthetic procedures and the efficiency of these procedures were compared. One method relies on classical heterocyclic synthesis, the other one aims at late-stage decoration of a truncated scaffold via direct C–H functionalization. A pharmacological evaluation disclosed that one of the synthesized derivatives showed interesting activity on a α1β3 containing receptor subtype.

摘要 通过两种合成方法制备了一系列取代的咪唑喹啉类化合物,这些化合物在结构上与吡唑喹啉酮类化合物(一类著名的 GABAA 配体)相关,并对这两种方法的效率进行了比较。一种方法依赖于经典的杂环合成,另一种方法旨在通过直接 C-H 功能化对截短的支架进行后期装饰。药理评估显示,合成的一种衍生物对含有α1β3受体亚型的受体具有有趣的活性。
