ABSTRACT:
derivatives, substituted at the 5-position of the indole nucleus by a five-membered heteroaromatic moiety, and on the phenyl ring of the phenethyl moiety by fluoro, chloro, 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 while possessing at least a 10-fold selective affinity for the 5-HT.sub.1D .alpha. receptor subtype relative to the 5-HT.sub.1D .alpha. subtype; they are therefore usefull 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, while eliciting fewer side-effects, notably adverse cardiovascular events, than those associated with non-subtype-selective 5-HT.sub.1D receptor agonists.
