  • 1,4-diazabicyclo [2.2.2] oct-2-ylmethyl derivatives, their preparation and therapeutic application
    Patent number: 6057321
    Abstract: The invention concerns compounds of general formula (I) ##STR1## in which R.sub.1 represents a methyl group, X.sub.1 represents a hydrogen atom, or OR.sub.1 and X.sub.1 together form a group of formula --O(CH.sub.2).sub.2 --,--O(CH.sub.2).sub.3 --, --O(CH.sub.2).sub.2 O-- or --O(CH.sub.2).sub.3 O--, X.sub.2 represents a hydrogen atom or an amino group, and X.sub.3 representing a halogen atom. The compounds are ligands of serotoninergic receptors of the 5-HT.sub.3 and/or 5-HT.sub.4 types, and act as 5-HT.sub.4 agonists and/or 5-HT.sub.3 antogonists.
