NEW PYRROLIDIN-2-OXOCARBOXYLIC, PIPERIDIN-2-OXOCARBOXYLIC AND AZEPIN-2-OXOCARBOXYLIC ACID-ESTERS ARE PREFERENTIAL M(1)-MUSCARINIC, M(3)-MUSCARINIC ANTAGONISTS - SYNTHESIS AND BRONCHOSPASMOLYTIC ACTIVITY

A series of new 3-tropanol and 3-quinuclidinol esters of phenyl-substi
tuted pyrrolidin-, piperidin- and azepin-2-oxocarboxylic acid were syn
thesized and tested for antimuscarinic activity. The compounds showed
a preferential in vitro activity at M(1) and M(3) receptor subtypes an
d an interesting activity profile in vivo. A potential use as selectiv
e bronchospasmolytic agents has been suggested for selected compounds.
