DESCRIPTION:

BRIEF SUMMARY
This application is a National Stage application of PCT/EP93/00738 filed Mar. 25, 1993 and published as WO 93/21177 on Oct. 28, 1993.
The present invention relates to indole derivatives which act on 5-hydroxytryptamine (5-HT) receptors.
More particularly the present invention relates to 3,5-disubstituted indoles which are selective agonists at the "5-HT.sub.1 -like" subtype of the 5-hydroxytryptamine receptor. Such "5-HT.sub.1 -like" receptors are present in the carotid vascular bed and their activation causes vasoconstriction with a consequent reduction in carotid blood flow. Compounds which have "5-HT.sub.1 -like" agonist activity are therefore useful in the treatment of medical conditions which are thought to result from excessive dilation of the carotid bed, such as migraine, cluster headache, chronic paroxysmal hemicrania and headache associated with vascular disorders. Certain compounds of the present invention are also agonists at central 5-HT.sub.1 receptors and are therefore useful for the treatment of depression, anxiety, eating disorders, obesity and drug abuse.
The present invention provides compounds of formula: ##STR2## and pharmaceutically acceptable salts thereof, wherein C.sub.1 -C.sub.3 alkylene; (R.sup.5 R.sup.6 NOC) C.sub.1 -C.sub.3 alkylene; (R.sup.5 R.sup.6 NO.sub.2 S)C.sub.1 -C.sub.3 alkylene; [R.sup.3 S(O).sub.m ]C.sub.1 -C.sub.3 alkylene; (R.sup.7 O) C.sub.2 -C.sub.4 alkylene; (C.sub.3 -C.sub.7 cycloalkyl) C.sub.1 -C.sub.3 alkylene; (aryl) C.sub.1 -C.sub.3 alkylene; (heteroaryl)C.sub.1 -C.sub.3 alkylene; C.sub.3 -C.sub.7 cycloalkyl optionally substituted with HO; C.sub.3 -C.sub.6 alkenyl optionally substituted with aryl; C.sub.5 -C.sub.7 cycloalkenyl; or C.sub.3 -C.sub.6 alkynyl; NOC)C.sub.1 -C.sub.3 alkylene; R.sup.8 R.sup.9 NO.sub.2 S; (R.sup.8 R.sup.9 NO.sub.2 S) C.sub.1 -C.sub.3 alkylene; R.sup.10 S (O).sub.m ; [R.sup.10 S (O).sub.m ]C.sub.1 -C.sub.3 alkylene; R.sup.12 CON (R.sup.11); [R.sup.12 CON(R.sup.11)]C.sub.1 -C.sub.3 alkylene; R.sup.10 SO.sub.2 N(R.sup.11); [R.sup.10 SO.sub.2 N(R.sup.11)]C.sub.1 -C.sub.3 alkylene; R.sup.8 R.sup.9 NOCN(R.sup.11); [R.sup.8 R.sup.9 NOCN(R.sup.11)]C.sub.1 -C.sub.3 alkylene; R.sup.10 O.sub.2 CN(R.sup.11); [R.sup.10 O.sub.2 CN(R.sup.11)]C.sub.1 -C.sub.3 alkylene; R.sup.13 (CH.sub.2).sub.n CH.dbd.CH; or R.sup.7 O; -C.sub.3 alkylene; (aryl) C.sub.1 -C.sub.3 alkylene; C.sub.3 -C.sub.7 cycloalkyl; or aryl; -C.sub.3 alkylene; (aryl)C.sub.1 -C.sub.3 alkylene; or C.sub.3 -C.sub.7 cycloalkyl; -C.sub.6 alkyl; (C.sub.3 -C.sub.7 cycloalkyl)C.sub.1 -C.sub.3 alkylene; (aryl)C.sub.1 -C.sub.3 alkylene; and C.sub.3 -C.sub.7 cycloalkyl; attached form a 4- to 7-membered heterocyclic ring which may optionally incorporate a further heteroatom linkage selected from O, S(O).sub.m, NH, N(C.sub.1 -C.sub.4 alkyl), and N(C.sub.1 -C.sub.5 alkanoyl); -C.sub.3 alkylene; (aryl)C.sub.1 -C.sub.3 alkylene; C.sub.3 -C.sub.7 cycloalkyl; or aryl; -C.sub.6 alkyl; (C.sub.3 -C.sub.7 cycloalkyl)C.sub.1 -C.sub.3 alkylene; (aryl)C.sub.1 -C.sub.3 alkylene; and C.sub.3 -C.sub.7 cycloalkyl;
