A class of 1-[3-(1H-indol-3-yl)propyl]-4-(2-phenylethyl)piperazine derivatives, substituted at the 5-position of the indole nucleus by a five-membered heteroaromatic moiety, on one or other of the ethylene carbon atoms of the phenethyl moiety by halogen, trifluoromethyl, alkyl, hydroxyalkyl or alkoxyalkyl, and optionally on the phenyl ring of the phenethyl moiety by halogen, trifluoromethyl, alkoxy or an oxazolidinone group and optionally by one or two further substituents, 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.

5-HT(1D/1B) receptoragonists are now entering the marketplace as treatments for migraine. This paper describes the development of selective h5-HT(1D) receptoragonists as potential antimigraine agents which may produce fewer side effects. A series of 3-[3-(piperidin-1-yl)propyl]indoles has been synthesized which has led to the identification of 80 (L-772,405), a high-affinity h5-HT(1D) receptor full agonist

(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.
