A class of 1-\x9b3-(1H-indol-3-yl)propyl!-4-benzylpiperazine derivatives of formula I, substituted at the 5-position of the indole nucleus by a 1,2,4-triazol-4-yl moiety, and on the methylene linkage of the benzyl moiety by a range of substituted alkyl groups, 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##
公式I的1-\x9b3-(1H-吲哚-3-基)丙基!-4-苄基哌嗪衍生物类,其在吲哚核的5位被1,2,4-三唑-4-基取代,并且在苄基部分的亚甲链上被一系列取代烷基基团取代,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/或预防临床病症方面具有用处,特别是偏头痛及相关疾病,对于这些疾病,需要5-HT.sub.1D受体亚型选择性激动剂,同时引起的副作用较少,尤其是不良心血管事件,而非亚型选择性5-HT.sub.1D受体激动剂相关的副作用。
