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-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 recptor agonists.
一类N-取代哌嗪、哌啶和四氢吡啶衍生物,通过含氟取代的烷基链连接到融合的双环杂芳基团(如吲哚),并在4-位进一步取代为可选择取代的烯烃基、炔基、芳基-烷基或杂芳基-烷基团,是5-HT.sub.1-类受体的选择性激动剂,是人类5-HT.sub.1D.alpha.受体亚型的有效激动剂,同时相对于5-HT.sub.1D.beta.亚型具有至少10倍的选择性亲和力;因此,它们在治疗和/或预防临床疾病中特别是偏头痛及相关疾病方面具有用处,这些疾病需要5-HT.sub.1D受体的亚型选择性激动剂,同时引起的副作用较少,尤其是不良心血管事件,相比于与非亚型选择性5-HT.sub.1D受体激动剂相关的副作用。
