A compound of structure (I), in which A.sup.1 is O, S(O).sub.n in which n is 0, 1 or 2, NR, CH.sub.2, or CH(OH); A.sup.2 is a bond or CH.sub.2 ; or A.sup.1 A.sup.2 is CH.dbd.CH; R is hydrogen or C.sub.1-4 alkyl; R.sup.1 is an optionally substituted 6- to 10-membered aryl or heteroaryl ring; suitably R.sup.1 is an optionally substituted 6- 10-membered aryl ring such as phenyl or naphthyl; suitably R.sup.1 is optionally substituted 6- to 10-membered heteroaryl ring, containing from 1 to 4 nitrogen atoms; R.sup.2 is hydrogen, halogen, C.sub.1-4 alkyl, CN, NO.sub.2 or CF.sub.3 ; R.sup.3 is C(R.sup.4)(R.sup.5)CH.sub.2 NR.sup.6 R.sup.7, --CH.dbd.NNHC(NH)NH.sub.2 or a; R.sup.4 and R.sup.5 are independently hydrogen or C.sub.1-4 alkyl; R.sup.6 and R.sup.7 are the same or different and are each hydrogen or C.sub.1-4 alkyl or together with the nitrogen atom to which they are attached form a ring; R.sup.8 is hydrogen, C.sub.1-4 alkyl, or C.sub.3-6 alkenyl; the dotted lines represent an optional bond; and q and m are independently 1 or 2; and pharmaceutically acceptable salts, solvates and hydrates thereof. The compounds are 5-HT.sub.1 -like agonists (or partial agonists) and as such are expected to have utility in medicine in the treatment and/or prophylaxis of migraine, and other conditions associated with cephalic pain, such as cluster headache, headache associated with vascular disorders and other neuralgia. They are also expected to have utility in the treatment of prophylaxis of portal hypertension. ##STR1##
