Imidazole, triazole and tetrazole derivatives of formula (I) are selective agonists of 5-HT.sub.1 -like receptors and are therefore useful in the treatment of clinical conditions, in particular migraine and associated disorders, for which a selective agonist of these receptors is indicated, wherein the broken circle represents two non-adjacent double bonds in any position in the five-membered ring; two, three or four of V, W, X, Y and Z represent nitrogen and the remainder represent carbon provided that, when two of V, W, X, Y and Z represent nitrogen and the remainder represent carbon, then the said nitrogen atoms are in non-adjacent positions within the five-membered ring; E represents a bond or a straight or branched alkylene chain containing from 1 to 4 carbon atoms; F represents a group of formula (a); U represents nitrogen or C--R.sup.2 ; B represents oxygen, sulphur or N--R.sup.3 ; R.sup.1 represents a group of formula (i), (ii) or (iii).
公式(I)的咪唑,三唑和四唑衍生物是5-HT.sub.1-类受体的选择性激动剂,因此在治疗临床病症,特别是偏头痛和相关疾病时非常有用,其中断开的圆圈表示五元环中任何位置的两个非相邻双键;V、W、X、Y和Z中的两个,三个或四个表示氮,其余表示碳,前提是当V、W、X、Y和Z中有两个表示氮,其余表示碳时,所述氮原子位于五元环中的非相邻位置;E表示键或含有1至4个碳原子的直链或支链烷基链;F表示公式(a)的基团;U表示氮或C--R.sup.2;B表示氧,硫或N--R.sup.3;R.sup.1表示公式(i),(ii)或(iii)的基团。
