A series of homodimers of the well-known cholinergic agonist carbachol have been synthesized, showing the two agonist units symmetrically connected through a methylene chain of variable length. The new compounds have been tested on the five cloned muscarinic receptors (hM1-5) expressed in CHO cells by means of equilibrium binding studies, showing an increase in affinity by rising the number of methylene
已经合成了一系列众所周知的胆碱能激动剂卡巴胆碱的同型二聚体,显示了通过可变长度的亚甲基链对称连接的两个激动剂单元。已经通过平衡结合研究对新化合物在CHO细胞中表达的五个克隆毒蕈碱受体(hM1-5)进行了测试,通过将亚甲基单元的数量增加到7和9来显示亲和力的增加。在几内亚的功能性实验猪回肠和对CHO细胞上hM1,hM2和hM3上ERK1 / 2磷酸化的评估表明,新化合物具有毒蕈碱拮抗特性。动力学结合研究表明,某些被测化合物能够减慢NMS的解离速率,表明存在双位点行为。在hM1和hM2受体上进行的对接模拟
