improve the oral bioavailability of a recently discovered, novel structural class of 5-HT1A receptor agonists: aryl-[4-(6-R-pyridin-2-ylmethyl)-amino]-methyl}-piperidin-1 -yl-metha none. Incorporation of a fluorine atom in the beta-position to the amino function in the side chain led to analogues that exhibited, in general, enhanced and long-lasting 5-HT1A agonist activity in rats after oral administration
这项工作的目的是提高最近发现的新颖结构的5-HT1A受体激动剂的口服生物利用度:芳基-[4-(6-R-吡啶-2-基甲基)-氨基]-甲基}-哌啶-1-基-甲基无。在侧链氨基位置的β位置引入氟原子会导致类似物在口服后在大鼠中表现出增强的和持久的5-HT1A激动剂活性。氟原子在哌啶环的C-4位上的位置是最有利的,并且在测试的各种取代基中,氟的能力在改善该配体家族的口腔活性方面是独特的。因此,导数39、46,61和61与5-HT1A受体(与多巴胺能D2和肾上腺素α1受体相比)具有更高的亲和力和选择性,并且在体外和体内比其C-4脱氟类似物具有更强的5-HT1A激动剂活性。为了检查药效基团的构象与这种配体的激动活性水平之间的关系,我们合成了一系列的3-氯-4-氟苯基-(4-氟-4 [(5-(H或CH3 )-6-R-吡啶-2-基甲基)-氨基]-哌啶-1-基-++ ++甲酮衍生物,发现吡啶环上有5-甲
