为了产生具有镇痛活性的螺哌啶的新衍生物,合成了1,2,6-三甲基-4-哌啶酮中间体。骨架的取代引起构型和构象异构现象。尽管1,2,6-三甲基-4-哌啶酮具有对称性,但在1 H和13 C NMR谱图中仍存在两组不同的信号。据推测它们是由1,2,6-三甲基-4-哌啶酮的顺式/反式混合物产生的。与该解释相反,在1 H和13 C NMR光谱中仅观察到碳原子2和6处的甲基和氢的两个信号,通常预期一个为顺式-另一个为两个反式异构体。为了解决这一差异,研究了导致1 H和13 C NMR光谱的1,2,6-三甲基-4-哌啶酮的异构体混合物。1,2,6-三甲基-4-哌啶酮的顺式和反式异构体的椅子构象之间的能量差与1,2,6-三甲基-反式异构体平衡过程的势能面通过量子化学计算确定其椅子构象异构体之间的4-哌啶酮。通过高温和低温NMR测量来测量平衡过程的势垒高度,以确认理论结果。所有调查的结果都很好地吻合,并证明是顺式的-/在室温下存在1
The present invention concerns novel compounds, their preparation and their uses, therapeutic uses in particular. More specifically it concerns derivative compounds having at least two aromatic cycles, their preparation and their uses, in particular in the area of human or animal health. These compounds have an affinity for the biological receptors of neuropeptide Y, NPY, present in the central and peripheral nervous systems. The compounds of the invention are preferably NPY antagonists, and more particularly antagonists of sub-type NPY Y1, and can therefore be used for the therapeutic or prophylactic treatment of any disorder involving NPY. The present invention also concerns pharmaceutical compositions containing said compounds, their preparation and their uses, as well as treatment methods using said compounds.
