Patent number: 4957941Abstract: A new class of anti-spasmodic compounds having two branch chains is provided. The compounds have the general formula: ##STR1## where Y is H or OH;j is an integer from 0 to 4;k is an integer from 0 to 4, and whereinm is an integer from 1 to 4;n is an integer from 1 to 4;p is an integer from 1 to 4; andX may be nonexistent or may be O, S, NH or CH.sub.2 or salts thereof, but when X is nonexistent the terminal group in which both the n-chain and the p-chain is a methyl group. ##STR2## The reaction was performed under reflux condensation. Following the reaction, which was usually complete within a few hours, the acid chlorides were vacuum distilled and reacted with a thiol compound as described above.The compounds of this invention are anti-muscarinic agents (cholinergic-muscarinic receptor antagonists) which inhibit the actions of acetylcholine on autonomic effectors innervated by postganglionic cholinergic nerves as well as on smooth muscle that lacks cholinergic innervation.Type: GrantFiled: January 9, 1990Date of Patent: September 18, 1990Assignee: United Pharmaceuticals, Inc.Inventor: William M. Davis
