nervous system (CNS) activity, a series of N-(2-benzofuranylmethyl)-N′-(methoxyphenylalkyl)piperazines (16–21 and 26–31) were synthesized, anticipating that these ligands would better suit the structural requirements of the current σ1 pharmacophore. Affinities of these ligands for σ1 and σ2 receptors were investigated by means of radioligand binding assays, with the identification of N-(2-benzofurany
在我们继续探索具有中枢神经系统(CNS)活性的作为σ(σ)受体配体的二取代哌嗪衍生物中,一系列的N-(2-苯并呋喃基甲基)-N '-(甲氧基苯基烷基)哌嗪(16 – 21和26 – 31)的合成中,预计这些配体将能更好地适应当前的σ的结构要求1药效团。对于σ这些配体的亲和力1和σ 2受体的放射配体结合测定法来进行调查,同时的识别ñ - (2-苯并呋喃基) - ñ' - [3-(4-甲氧基苯基)丙基]哌嗪(29,ķ我 = 3.1纳米,σ 2 /σ 1 = 45),其为选择性σ 1配体。所述σ 1个的哌嗪的亲和力和选择性亚型16 - 21和26 - 31一般都比得上对应的苄基类似物。另外,对5-HT 2B受体的亲和力为16 – 21和26 – 31远低于相对非选择性的甲氧基苄基类似物2 – 4,表明σ烷基系绳通常改善的选择性的该伸长1受体。
