to the CH2 linked to the 1‐phenyl‐1,3,8‐triaza‐spiro[4.5]decan‐4‐one portion. Moreover, cis diastereoisomers of the hydroxyl derivatives4 and 22 show a moderately higher degree of stereoselectivity than trans isomers. In particular, the spiropiperidine derivative cis‐4 has submicromolar agonistic activity, and it will be the reference compound for the design and synthesis of new NOP agonists.
合成了几种螺索托林衍生物,并将其评估为潜在的NOP受体配体。螺氧杂环丁烷的1,4-苯并二恶烷部分的结构修饰一直是该研究项目的重点。出现的结构-活性关系表明,当H-键供体基团(羟基)相对于与1-苯基-1,3连接的CH 2处于α位置时,它更有利于NOP活性, 8-triaza-spiro [4.5] decan-4-一份。此外,羟基衍生物4和22的顺式非对映异构体显示出比反式异构体适度更高的立体选择性。尤其是螺哌啶衍生物cis - 4具有亚微摩尔激动活性,它将成为设计和合成新的NOP激动剂的参考化合物。
