A series of novel 3-phenyl-3-[1-(cyclicalkyl)pyrrolidin-3-yl]glutarimide derivatives have been prepared, including their pharmaceutically acceptable salts. The cyclic moiety present in these compounds is derived from either benzene or a heteroaryl such as benzofuran or 2,3-dihydrobenzofuran, or it is derived from an aromatic heterocyclic such as pyridine, pyrazine or thiophene, and it is attached to the adjacent alkyl group of the molecule by means of one of the available ring carbon atoms situated in the aromatic ring of the aforementioned cyclic ring moiety. These particular compounds are useful in therapy as selective muscarinic receptor antagonists, which are selective for smooth muscle muscarinic sites over cardiac muscarinic sites and therefore, are of value in the treatment of diseases associated with altered motility and/or smooth muscle tone as found in the gut, trachea and bladder. Methods for preparing these compounds from known starting materials are provided.
一系列新型的3-苯基-3-[1-(环烷基)吡咯烷-3-基]戊二酰亚胺衍生物已经制备出来,包括它们的药物可接受的盐。这些化合物中存在的环状基团是从苯或杂环芳烃如苯并呋喃或2,3-二氢苯并呋喃中衍生出来的,或者是从芳香杂环化合物如吡啶、吡嗪或噻吩中衍生出来的,并且它通过上述环状基团中芳香环的一个可用环碳原子连接到分子的相邻烷基团上。这些特定的化合物在治疗中是有用的,作为选择性肌肉乙酰胆碱受体拮抗剂,其对平滑肌乙酰胆碱受体位点具有选择性,而不是心脏乙酰胆碱受体位点,因此,在与肠道、气管和膀胱中发现的改变运动性和/或平滑肌张力相关的疾病的治疗中具有价值。提供了从已知起始材料制备这些化合物的方法。
