Substituted 4‐heteroaryl‐2‐phenylquinolines were synthesized and tested on NK‐2 and NK‐3 receptors in order to get a better insight in the structure‐activity relationship. On the whole, these molecules, which can be regarded as bioisosters of the NK‐3 antagonist SB 218795, displayed a lower activity than the template. Ring electronic distribution and H‐bond donor and acceptor positions played some
为了更好地了解构效关系,合成了取代的 4-杂芳基-2-苯基喹啉并在 NK-2 和 NK-3 受体上进行了测试。总的来说,这些可被视为 NK-3 拮抗剂 SB 218795 的生物电子等排体的分子显示出比模板低的活性。环电子分布和H-键供体和受体位置在选择性中起一定作用,2-咪唑基取代的2a主要对NK-3表现出亲和力,而3-吡唑基取代的4表现出与NK-2受体的优先相互作用。合成化合物的结构表征是通过核磁共振和质谱技术实现的。二维 1H-NOESY 实验是确定化合物 9 和 11b – c 的异构结构的有用工具。
