A class of substituted pyrrolo[2,3-c]pyridine derivatives are selective agonists of 5-HT.sub.1 -like receptors and are therefore useful in the treatment of clinical conditions, in particular migraine and associated disorders, for which a selective agonist of these receptors is indicated.
A class of substituted azetidine, pyrrolidine and piperidine derivatives are selective agonists of 5-HT.sub.1 -like receptors, being potent agonists of the human 5-HT.sub.1D.alpha. receptor subtype whilst possessing at least a 10-fold selective affinity for the 5-HT.sub.1D.alpha. receptor subtype relative to the 5-HT.sub.1D.beta. subtype; they are therefore useful in the treatment and/or prevention of clinical conditions, in particular migraine and associated disorders, for which a subtype-selective agonist of 5-HT.sub.1D receptors is indicated, whilst eliciting fewer side-effects, notably adverse cardiovascular events, than those associated with non-subtype-selective 5-HT.sub.1D receptor agonists.

(EN) A class of substituted azetidine, pyrrolidine and piperidine derivatives are selective agonists of 5-HT1-like receptors, being potent agonists of the human 5-HT1D$g(a) receptor subtype whilst possessing at least a 10-fold selective affinity for the 5-HT1D$g(a) receptor subtype relative to the 5-HT1D$g(b) subtype; they are therefore useful in the treatment and/or prevention of clinical conditions, in particular migraine and associated disorders, for which a subtype-selective agonist of 5-HT1D receptors is indicated, whilst eliciting fewer side-effects, notably adverse cardiovascular events, than those associated with non-subtype-selective 5-HT1D receptor agonists.(FR) Classe de dérivés substitués de l'azétidine, de la pyrrolidine et de la pipéridine constituant des agonistes sélectifs des récepteurs du genre 5-HT1 qui sont puissants agonistes du sous-type de récepteur humain 5-HT1D$g(a) tout en possédant une affinité sélective au moins 10 fois plus forte pour le sous-type 5-HT1D$g(a) que le sous-type 5-HT1D$g(b). Ils s'avèrent de ce fait utiles dans le traitement et/ou la prévention d'états cliniques tels que la migraine ou des troubles associés pour lesquels un sous-type sélectif d'agoniste des récepteurs du 5-HT1D est indiqué, tout en provoquant moins d'effets secondaires, tels que certains phénomènes cardio-vasculaires adverses, que ceux qui sont associés à des agonistes non sélectifs du sous-type du récepteur du 5-HT1D.
