A class of N-substituted piperazine, piperidine and tetrahydropyridine derivatives, linked by a fluoro-substituted alkylene chain to a fused bicyclic heteroaromatic moiety such as indolyl, and further substituted at the 4-position by an optionally substituted alkenyl, alkynyl, aryl-alkyl or heteroaryl-alkyl moiety, are selective agonists of 5-HT1-like receptors, being potent agonists of the human 5-HT1Dα receptor subtype whilst possessing at least a 10-fold selective affinity for the 5-HT1Dα receptor subtype relative to the 5-HT1Dβ 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 recptor agonists. |
