alpha-position in the acetylenic chain (8b) were antagonists. Various analogues of these imidazole acetylenes where the pyrrolidinone ring was replaced by an amide, carbamate, or urea residue were prepared. Several compounds which contained 5-methylimidazole as the amine substituent were partial agonists. The activities of the imidazole compounds are compared with those of the related pyrrolidine and dimethylamine

Some urea and 2-imidazolidone analogues of the muscarinic agents oxotremorine (1) and N-methyl-N-(1-methyl-4-pyrrolidino-2-butynyl)acetamide [10; BM-5] have been synthesized and assayed for muscarinic and antimuscarinic activity on the isolated guinea pig ileum. The new compounds (15-24) were found to be muscarinicagonists, partial agonists, or antagonists. The compounds were also tested for in vitro
