  Synthesis and SAR of Adatanserin:  Novel Adamantyl Aryl- and Heteroarylpiperazines with Dual Serotonin 5-HT_1A and 5-HT₂ Activity as Potential Anxiolytic and Antidepressant Agents

  摘要：

  Several novel functionalized adamantyl aryl- and heteroarylpiperazine derivatives were prepared and examined in various receptor binding and behavioral tests to determine their serotonin receptor activities. Many compounds demonstrated modest to high affinity for 5-HT1A receptors, with compounds 9, 13, 23, 33, 34, and 43 being the most potent at this site. Compound 1, 2-[4-(2-pyrimidinyl)-1-piperazinyl] ethyl adamantyl-1-carboxylate, demonstrated relatively high affinity for 5-HT1A receptors (K-i = 8 nM) and acceptable selectivity versus D-2 receptors (K-i = 708 mM); however, it lacked in vivo activity in serotonergic behavioral models. In contrast, compounds 9 (WY-50,324, SEB-324, adatanserin), adamantyl-1-carboxylic acid 2-[4-(2-pyrimidinyl)-1-piperazinyl]ethylamide, and 13, adamantyl-1-carboxylic acid 2-[4-(2-methoxyphenyl)-1-piperazinyl] ethylamide, demonstrated high affinity for 5-HT1A binding sites (K-i = 1 nM for both) and moderate affinity for 5-HT2 receptors (K-i = 73 and 75 nM, respectively). Both compounds also demonstrated partial 5-HT1A agonist activity in vivo in rat serotonin syndrome and 5-HT2 antagonist activity in quipazine- and DOI-induced head shake paradigms. The selective 5-HT1A partial agonist and 5-HT2 antagonist activity of 9 was accompanied by significant anxiolytic activity in an animal conflict model. On the basis of this profile, compound 9 entered development as a combined anxiolytic and antidepressant agent.
