PCT No. PCT/GB95/01819 Sec. 371 Date Jan. 22, 1997 Sec. 102(e) Date Jan. 22, 1997 PCT Filed Aug. 1, 1995 PCT Pub. No. WO96/04274 PCT Pub. Date Feb. 15, 1996A class of substituted azetidine, pyrrolidine and piperidine derivatives are selective agonists of 5-HT1-like receptors, being potent agonists of the human 5-HT1D alpha receptor subtype whilst possessing at least a 10-fold selective affinity for the 5-HT1D alpha receptor subtype relative to the 5-HT1D 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-HT1D receptors is indicated, whilst eliciting fewer side-effects, notably adverse cardiovascular events, than those associated with non-subtype-selective 5-HT1D receptor agonists. |
