A series of triazospirodecanone derivatives were synthesized as potential NOP ligands. 8-(Chroman-4-yl)-1-phenyl-1,3,8-triazaspiro[4.5]decan-4-one (4) and its 5-fluoro analogue (18) proved to be active as agonists with EC50 values in the submicromolar range. Single enantiomers of compound 4 were separated and tested as NOP agonists; the eutomer R-(+)-4 showed a pEC50 of 7.34. Finally docking studies were performed on the NOP receptor to identify the most significant stereospecific interactions.
一系列三氮杂螺癸烷-4-酮衍生物被合成作为潜在的NOP配体。8-(色满-4-基)-1-苯基-1,3,8-三氮杂螺[4.5]癸烷-4-酮(4)及其5-氟类似物(18)被证明是具有亚微摩尔级EC50值的激动剂。化合物4的单一旋光异构体被分离并测试为NOP激动剂;优旋体R-(+)-4显示出7.34的pEC50值。最后,对NOP受体进行了对接研究,以识别最重要的立体特异性相互作用。
