Compounds are disclosed of general formula (I) ##STR1## wherein R.sub.1 represents a group CHO, COR.sub.8, CO.sub.2 R.sub.8, CONR.sub.9 R.sub.10, CSNR.sub.9 R.sub.10 or SO.sub.2 NR.sub.9 R.sub.10, where R.sub.8 represents an alkyl, cycloalkyl, aryl or aralkyl group, R.sub.9 represents a hydrogen atom or an alkyl group, and R.sub.10 represents a hydrogen atom or an alkyl, cyclo-alkyl, aryl or aralkyl group; R.sub.2, R.sub.3, R.sub.4, R.sub.6 and R.sub.7, which may be the same or different, each represents a hydrogen atom or a C.sub.1-3 alkyl group; R.sub.5 represents a hydrogen atom or an alkyl, cycloalkyl, alkenyl or an aralkyl group or R.sub.4 and R.sub.5 together form an aralkylidene group or R.sub.4 and R.sub.5 together with the nitrogen atom to which they are attached form a saturated monocyclic 5- to 7-membered ring; and Alk represents an alkylene chain containing two or three carbon atoms which may be unsubstituted or substituted by not more than two C.sub.1-3 alkyl groups; with the provisos that when R.sub.4 and R.sub.5 both represent alkyl groups R.sub.1 does not represent the group CHO or COR.sub.8 and that when R.sub.4, R.sub.5, R.sub.6 and R.sub.7 all represent hydrogen R.sub.1 does not represent the group SO.sub.2 NH.sub.2 ; and physiologically acceptable salts, solvates and bioprecursors thereof. The components are described as potentially useful for the treatment of migraine and may be formulated as pharmaceutical compositions in convention manner using one or more pharmaceutically acceptable carriers or excipients. Various processes for the preparation of the compounds are disclosed including, for example, reaction of an aminoalkyl indole with an acid of formula R.sub.1 OH or an acylating agent corresponding thereto or with an inorganic cyanate or an organic isocyanate or isothiocyanate in order to introduce the desired R.sub.1 group at the 5-position on the indole nucleus.
