Discovery of novel quaternary ammonium derivatives of (3R)-quinuclidinyl carbamates as potent and long acting muscarinic antagonists

Novel quaternary ammonium derivatives of N,N-disubstituted (3R)-quinuclidinyl carbamates have been identified as potent M3 muscarinic antagonists with long duration of action in an in vivo model of bronchoconstriction. These compounds have also presented a high level of metabolic transformation (human liver microsomes). The synthesis, structure-activity relationships and biological evaluation of these compounds are reported.

PROCESS FOR PREPARING QUINUCLIDINIUM CARBAMATE DERIVATIVES

The invention relates to a new process for preparing carbamate derivatives having the structure of formula (I) by reacting, in a first step, a compound of formula (II) with a compound of formula (III) and reacting the product of this first step with an ac

NOVEL QUINUCLIDINE DERIVATIVES AND MEDICINAL COMPOSITIONS CONTAINING THE SAME

Carbamates of formula (I) or pharmaceutically acceptable salts thereof, including quaternary ammonium salts of formula (II) are disclosed; as well as processes for their preparation, pharmaceutical compositions comprising them and their use in therapy as antagonists of M3 muscarinic receptors.
