5-alkenyl and 5-alkynyl indole compounds

Abstract

Described herein are compounds selective for 5-HT.sub.1D -like receptors, which have the general formula: ##STR1## wherein: R.sup.1 is selected from H, aryl and aryl substituted with 1, 2 or 3 substituents independently selected from loweralkyl, loweralkoxy, loweralkylcarbonyl, loweralkyl-S--, loweralkyl-S(O)--, loweralkyl-SO.sub.2 -, S.dbd.C.dbd.N--, O.dbd.C.dbd.N--, halo, loweralkoxycarbonyl, nitro, amino, loweralkyl-NH--, (loweralkyl).sub.2 --N--, loweralkyl-SO.sub.2 -loweralkyl-; A is a double or triple bond; R.sup.2 is selected from a group of Formula II, III, IV and V: ##STR2## R.sup.3 is selected from H and loweralkyl; R.sup.4 is selected from H and loweralkyl; One of R.sup.5 and R.sup.6 is H and the other is independently selected from H, loweralkoxy, loweralkyl and hydroxy; and R.sup.7 and R.sup.8 are independently selected from H and loweralkyl or R.sup.7 and R.sup.8, together with the nitrogen atom to which they are attached, form an optionally substituted 3- to 6-membered ring; or a salt, solvate or hydrate thereof. Also described is the use of these compounds as pharmaceuticals to treat indications where stimulation of the 5-HT.sub.1D -like receptor is implicated, such as migraine.
