  Synthesis and structure–activity relationship of 2-(aminoalkyl)-2,3,3a,8-tetrahydrodibenzo[c,f]isoxazolo[2,3-a]azepine derivatives: a novel series of 5-HT2A/2C receptor antagonists. Part 1

  摘要：

  The synthesis of a series of novel 2-(aminoalkyl)-2,3,3a,8-tetrahydrodibenzo[c,f]isoxazolo[2,3-a]azepine derivatives as well as their 5-HT2A/2C and H-1 receptor binding affinities are described. The in vivo activity as potential anxiolytics of the svnthesised compounds was measured in a mCPP challenge test. One of the compounds, 2a, proved to be a potent 5-HT2A 2C c receptor antagonist showing as well oral activity and therefore could be considered as a potential anxiolytic/antidepressant agent.
