Abstract
A series of N-substituted analogs based upon the spiropiperidine core of the lead compound Spiroxatrine was synthesized. In particular, the new compounds were obtained by replacing the benzodioxane moiety of the Spiroxatrine with several 2-substituted 1,3-dioxolanes. Thus the designed derivatives were synthesized and evaluated as possible NOP receptor ligands. As a conclusion of these studies, the new triazaspirodecanone derivatives showed unique and significant SAR as NOP receptor agonists. In particular, the present study demonstrated that 1-phenyl-1,3,8-triazaspiro[4.5]decan-4-one portion together with appropriate 1,3-dioxolane substituents could lead to a new promising class of NOP receptor ligands.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
