The present invention relates to novel N-substituted azaheterocyclic carboxylic acids and esters thereof in which a substituted alkyl chain forms part of the N-substituent or salts thereof, to methods for their preparation, to compositions containing them, and to their use for the clinical treatment of painful, hyperalgesic and/or inflammatory conditions in which C-fibers play a pathophysiological role by eliciting neurogenic pain or inflammation.

Heterocyclic compounds

The present invention relates to novel N-substituted azaheterocyclic carboxylic acids and esters thereof in which a substituted alkyl chain of the N-substituent or salts thereof, to methods for their preparation, to compositions containing them, and to their use for the clinical treatment of painful, hyperalgesic and/or inflammatory conditions in which C-fibers play a pathophysiological role by eliciting neurogenic pain or inflammation.

N-substituted azaheterocyclic carboxlic acids and esters thereof

N-substituted azaheterocyclic carboxylic acids and esters thereof

Novel O-alkylated oximes of the general formula I ##STR1## or ##STR2## wherein R.sup.1 and R.sup.2 are optionally substituted aromatic or heteroaromatic rings, R.sup.3 is hydrogen or lower alkyl, R.sup.4 is a nitrogen containing, substituted ring or an amino group carrying a substituted ring, and n and m independently are 0, 1 or 2, are potent inhibitors of GABA reuptake from the synaptic cleft.
