oxotremorine M, pirenzepine, and quinuclidinyl benzilate as ligands and were supported by studies on the isolated guinea pig ileum. The degree of muscarinic agonist activity of the compounds (M-agonist index) and their selectivity for M-1 or M-2 muscarinic receptor subtypes (M-2/M-1 index) were estimated on the basis of receptor-binding studies. The in vitro pharmacological profiles of the compounds
已经合成了许多构象受限的3-烷氧基-4,5,6,7-四氢异恶唑并[4,5-c]吡啶(O-烷基-THPO)型毒蕈碱激动剂的S-甲基ulf类似物。这些3-烷氧基-5-甲基-6,7-二氢-4H-硫代吡喃并[3,4-d]异恶唑-5-鎓(O-烷基-S-甲基-DHTO)类似物对毒蕈碱受体的影响(7a -d)在tri结合的奥曲莫林M,哌仑西平和苯甲酸奎宁环酯作为配体的受体结合实验中进行了评估,并得到了对分离的豚鼠回肠的研究的支持。在受体结合研究的基础上,估算了化合物的毒蕈碱激动剂活性的程度(M-激动剂指数)及其对M-1或M-2毒蕈碱受体亚型的选择性(M-2 / M-1指数)。将该化合物的体外药理学特征与槟榔碱及其are和3-甲氧基异恶唑等排体,磺基槟榔碱和O,5-二甲基-THPO分别进行了比较。尽管O-甲基-DHTO(5a)和N-甲基-DHTO(6a)处于非活性状态,但所有的sulf类似物7a-d均为毒
