Analogs of the 5-HT1A receptor antagonist (S)-5-fluoro-8-hydroxy-2-(dipropylamino)tetralin [(S)-1,(S)-UH301] have been prepared. The C8-substituent has been varied, and in some derivatives one of the N-propyl groups has been exchanged for a 4-(8-aza-7,9-dioxospiro[4.5]decan-8-yl)-butyl group. The novel compounds have been evaluated for affinity to rat brain 5-HT1A receptors in competition experiments
已经制备了5-HT1A受体拮抗剂(S)-5-氟-8-羟基-2-(二丙基氨基)四氢化萘[(S)-1,(S)-UH301]的类似物。C 8取代基已经变化,并且在一些衍生物中,N-丙基之一已被交换为4-(8-氮杂-7,9-二氧杂螺并[4.5] decan-8-基)-丁基。在与[3H] -8-OH-DPAT的竞争实验中,已经评估了该新型化合物对大鼠脑5-HT1A受体的亲和力。另外,通过化合物在表达大鼠5-HT1A受体的GH4ZD10细胞中抑制VIP刺激的cAMP形成的能力来评估化合物的功效。在所测试的化合物中揭示出不同程度的内在活性,即分布范围从完全激动剂到拮抗剂。所有R对映异构体均被表征为对5-HT1A受体的完全激动剂,而在相应的S-对映异构体中发现了部分激动剂或拮抗剂。用一个N-丙基取代4-(8-氮杂-7,9-二氧杂螺并[4.5]十烷-8-基)丁基似乎增加了功效以及对5-HT1A受体的亲和力。
