quaternary analogues (acyclic imides, sulfonimides, N-acetyl sulfonamides, and trifluoroacetamides) of the selective partial muscarinic agonist N-methyl-N-(1-methyl-4-pyrrolidino-2-butynyl)acetamide (BM 5,35) was synthesized. The compounds were found to be muscarinic agonists, partial agonists, or antagonists in the isolated guinea pig ileum. Replacement of the acetyl group or the N-methyl group of
选择性部分毒蕈碱激动剂N-甲基-N-(1-甲基-4-吡咯烷基-2-丁炔基)乙酰胺(BM 5)的一系列叔和季类似物(无环酰亚胺,磺酰亚胺,N-乙酰磺酰胺和三氟乙酰胺) ,35)合成。发现化合物是分离的豚鼠回肠中的毒蕈碱激动剂,部分激动剂或拮抗剂。用甲磺酰基取代35的乙酰基或N-甲基及其类似物可消除功效,并降低对回肠毒蕈碱受体的亲和力。35的三氟乙酰胺类似物也比35具有更低的亲和力和效力。在与35有关的化合物中用乙酰基取代N-甲基会降低效力,但对亲和力没有明显影响。
