A class of piperazinones, homopiperazinones and thione analogues thereof, substituted at the 1-position by an optionally substituted alkenyl, alkynyl, aryl-alkyl or heteroaryl-alkyl moiety, and linked at the 4-position via an alkylene spacer to a fused bicyclic heteroaromatic moiety, typically indolyl, 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.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, while eliciting fewer side-effects, notably adverse cardiovascular events, than those associated with non-subtype-selective 5-HT.sub.1D receptor agonists.
一类哌嗪酮、同源哌嗪酮和其硫醚类似物,其在1位被可选择地取代的烯基、炔基、芳基-烷基或杂环芳基-烷基上,而在4位通过烷基间隔连接到融合的双环杂芳基上,通常是吲哚基,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.亚型至少具有10倍的选择性亲和力;因此,在特定的临床情况,特别是偏头痛及相关疾病的治疗和/或预防中,它们是有用的,因为需要5-HT.sub.1D受体的亚型选择性激动剂,而且其副作用较少,尤其是不良心血管事件,相对于与非亚型选择性5-HT.sub.1D受体激动剂相关的副作用。
