A class of substituted piperidine and tetrahydropyridine derivatives, linked through the 4-position thereof via an alkylene chain to a fused bicyclic heteroaromatic moiety such as indolyl, and further substituted at the 1-position by an optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl-alkyl, 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.spsb..alpha. receptor subtype whilst processing at least a 10-fold selective affinity for the 5-HT.sub.1D.spsb..alpha. receptor subtype relative to the 5-HT.sub.1D.spsb..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.
一类经过取代的哌啶和四氢吡啶衍生物,通过其4位点通过一条烷基链连接到融合的双环杂芳基团,如吲哚,并且在1位点进一步经过取代为一个可选择取代的烷基,烯基,炔基,环烷基-烷基,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.spsb..alpha.受体亚型的有效激动剂,同时相对于5-HT.sub.1D.spsb..beta.亚型至少具有10倍的选择性亲和力;因此,在治疗和/或预防临床疾病,特别是偏头痛和相关疾病方面,这些衍生物是有用的,因为这些疾病需要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,比与非亚型选择性5-HT.sub.1D受体激动剂相关的副作用。
