A class of substituted azetidine, pyrrolidine and piperidine derivatives of Formula I 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. ##STR1##

The design, synthesis, and biological evaluation of a novel series of 3-[2-(pyrrolidin-1-yl)ethyl]indoles with excellent selectivity for h5-HT1D (formerly 5-HT1Dalpha) receptors over h5-HT1B (formerly 5-HT1Dbeta) receptors are described. Clinically effective antimigraine drugs such as Sumatriptan show little selectivity between h5-HT1D and h5-HT1B receptors. The differential expression of h5-HT1D and
