We synthesized a new series of benextramine analogs as neuropeptide Y (NPY) functional group mimetics and tested them for N-[propionyl-3H]NPY ([3]NPY) displacement activity in rat brain membrane homogenates and for NPY receptor antagonist activity in the rat femoral artery. The tetraamine, carbon analog N,N'-bis[6-[N-(2-naphthylmethyl)amino]hexyl]-1,6-hexanediamine (15) was equipotent with benextramine
我们合成了一系列新的苯达明类似物作为神经肽Y(NPY)官能团模拟物,并测试了它们在大鼠脑膜匀浆中的N- [丙酰-3H] NPY([3] NPY)置换活性以及在大鼠脑膜匀浆中的NPY受体拮抗剂活性。大鼠股动脉。四胺碳类似物N,N'-双[6- [N-(2-萘基甲基)氨基]己基] -1,6-己二胺(15)与苯达拉明等价(基于相关IC50的比较)。大鼠脑[3H] NPY置换实验表明,二硫化物不是苯并明[3H] NPY取代活性的必要特征,尽管该类似物对苯并明敏感的结合位点群体具有选择性。bis(N,N-二烷基胍基二硫化物和碳类似物14a-c在从大鼠脑膜匀浆中置换[3H] NPY时的效价比其相应对照高3-4倍,IC50范围为15至18 microM,并保持了对苯丙胺敏感的选择性, Y1结合位点人口。但是,碳类似物N,N'-双[6- [N-(2-萘基甲基)氨基]己基] -N,N'-(1,6-己二基)双胍
