A class of N-substituted piperazine, piperadine and tetrahyrdopyridine derivatives of formula (I), further substituted at the 4-position by an optionally substituted 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 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. In formula (I) Z represents --SO.sub.2 NR.sup.5 R.sup.6, or a group of formula (b). ##STR1##
一类N-取代哌嗪、哌啶和四氢吡啶衍生物,其化学式为(I),在4-位进一步取代为可选取代的芳基-烷基或杂环芳基-烷基基团,是5-HT.sub.1-样受体的选择性激动剂,相对于5-HT.sub.1D.beta.亚型而言是人类5-HT.sub.1D.alpha.受体亚型的有效激动剂;因此,在治疗和/或预防临床疾病,特别是偏头痛及相关疾病方面,对于需要5-HT.sub.1D受体亚型选择性激动剂的情况,其产生的副作用较少,尤其是与非亚型选择性5-HT.sub.1D受体激动剂相关的不良心血管事件。在化学式(I)中,Z代表--SO.sub.2 NR.sup.5 R.sup.6,或者是化学式(b)的一个基团。
