ABSTRACT:
Compounds of the formula ##STR1## where A represents a direct bond, C.sub.1 -C.sub.4 alkyl, or C.sub.1 -C.sub.4 alkenyl; n is 0, 1, or 2; R.sub.1 is hydrogen, C.sub.1 -C.sub.6 alkyl, aryl, C.sub.1 -C.sub.3 alkylaryl, C.sub.1 -C.sub.3 alkylheteroaryl, or --(CH.sub.2).sub.m R.sub.6 ; W, X, Y, and Z are each independently oxygen, sulfur, nitrogen or carbon, provided that at least one of W, X, Y or Z is nitrogen; R.sub.2, R.sub.3, R.sub.4, and R.sub.5 are each independently hydrogen, C.sub.1 -C.sub.6 alkyl, aryl, C.sub.1 -C.sub.3 alkylaryl, C.sub.1 -C.sub.3 alkylheteroaryl, halogen, cyano, trifluommethyl, nitro, --OR.sub.7, --NR.sub.7 R.sub.8, --(CH.sub.2).sub.s OR.sub.7, --SR.sub.7, --SO.sub.2 NR.sub.7 R.sub.8, --NR.sub.7 SO.sub.2 R.sub.8, --NR.sub.7 CO.sub.2 R.sub.8, --CONR.sub.7 R.sub.8, or --CO.sub.2 R.sub.7 ; one of R.sub.2 and R.sub.3, R.sub.3 and R.sub.4, or R.sub.4 and R.sub.5 may be taken together to form a five- to seven-membered alkyl ring, a six-membered aryl ring, a five- to seven-membered heteroalkyl ring having 1 heteroatom of N, O, or S, or a five- to six-membered heteroaryl ring having 1 or 2 heteroatoms of N, O, or S; R.sub.6 is cyano, trifluoromethyl, or --OR.sub.9 ; R.sub.7, R.sub.8, and R.sub.9 are each independently hydrogen, C.sub.1 to C.sub.6 alkyl, --(CH.sub.2).sub.m R.sub.10, C.sub.1 to C.sub.3 alkylaryl, or aryl; R.sub.7 and R.sub.8 may be taken together to form a C.sub.4 -C.sub.7 alkyl ring; R.sub.10 is cyano, trifluoromethyl, or C.sub.1 -C.sub.4 alkoxy; R.sub.11 is hydrogen, --OR.sub.12, or --NHCOR.sub.12 ; R.sub.12 is C.sub.1 to C.sub.6 alkyl, aryl, or C.sub.1 to C.sub.3 alkyl-aryl; m is 1, 2, or 3; s is 0, 1, 2, or 3; and the above aryl groups and the aryl moleties of the above alkylaryl groups are independently selected from phenyl and substituted phenyl, wherein said substituted phenyl may be substituted with one to three groups selected from C.sub.1 to C.sub.4 alkyl, halogen, hydroxy, cyano, carboxamido, nitro, and C.sub.1 to C.sub.4 alkoxy, and the pharmaceutically acceptable salts thereof. These compounds are useful psychotherapeutics and are potent serotonin (5-HT.sub.1) agonists and may be used in the treatment of depression, anxiety, eating disorders, obesity, drug abuse, cluster headache, migraine, pain and chronic paroxysmal hemicrania and headache associated with vascular disorders, end other disorders arising from deficient serotonergic neurotransmission. The compounds can also be used as centrally acting antihypertensives and vasodilators.
