homopiperazine (4) derivatives, substituted at one nitrogen atom with the 6-chloro-3-pyridazinyl group while the other nitrogen atom was either unsubstituted or mono- or dimethylated, were synthesized and tested for their affinity toward the neuronal nicotinic acetylcholine receptors (nAChRs). All of the compounds had K(i) values in the nanomolar range. A molecular modeling study allowed location of
在一个氮原子上被6取代的3,8-二氮杂双环[3.2.1]辛烷(1),2,5-二氮杂双环[2.2.1]庚烷(2),哌嗪(3)和高哌嗪(4)衍生物合成了-氯-3-哒嗪基,而另一个氮原子未被取代或被单或二甲基化,并测试了它们对神经元烟碱乙酰胆碱受体(nAChRs)的亲和力。所有化合物的K(i)值均在纳摩尔范围内。分子建模研究确定了其优选构象的位置,并使用连续溶剂模型在水中重新计算了它们的能量。一些化合物以其填充的构型显示,仅药效上的距离长于Sheridan模型对nAChRs受体考虑的值。从而,
