The present invention relates to a compounds of formula (I) wherein R1 is hydrogen or lower alkyl; R2 is hydrogen, lower alkyl, lower alkyl substituted by halogen or is halogen or CN, and may be independently from each other if o is 2; Ar1 is aryl or heteroaryl; Ar2 is aryl or heteroaryl; R'/R" are independently from each other hydrogen, lower alkyl, lower alkoxy, halogen, C(O)- lower alkyl, cyano or lower alkyl substituted by halogen; m is 0, 1, or 2 when n is 0; or m is 0 or 1 when n is 1; n is 0 or 1; o is 1 or 2; or to pharmaceutically active salts, racemic mixtures, enantiomers, optical isomers or to tautomeric forms thereof. It has been found that the present compounds are high potential NK-3 receptor antagonists for the treatment of depression, pain, psychosis, Parkinson's disease, schizophrenia, anxiety and attention deficit hyperactivity disorder (ADHD).
本发明涉及式(I)的化合物,其中R1为
氢或较低烷基;R2为
氢、较低烷基、受卤素取代的较低烷基或卤素或CN,如果o为2,则它们可以彼此独立;Ar1为芳基或杂环芳基;Ar2为芳基或杂环芳基;R'/R"彼此独立地为
氢、较低烷基、较低烷
氧基、卤素、C(O)-较低烷基、
氰基或受卤素取代的较低烷基;当n为0时,m为0、1或2;当n为1时,m为0或1;n为0或1;o为1或2;或其药用活性盐、消旋混合物、对映体、光学异构体或其互变异构体。已发现这些化合物是治疗抑郁症、疼痛、精神病、帕
