Compounds of the formula <IMAGE> I where A represents a direct bond, C1-C4 alkyl, or C1-C4 alkenyl; n is 0, 1, or 2; R1 is hydrogen, C1-C6 alkyl, aryl, C1-C3 alkylaryl, C1-C3 alkylheteroaryl, or -(CH2)mR6; 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; R2, R3, R4, and R5 are each independently hydrogen, C1-C6 alkyl, aryl, C1-C3 alkylaryl, C1-C3 alkylheteroaryl, halogen, cyano, trifluommethyl, nitro, -OR7, -NR7R8, -(CH2)sOR7, -SR7, -SO2NR7R8, -NR7SO2R8, -NR7CO2R8, -CONR7R8, or -CO2R7; one of R2 and R3, R3 and R4, or R4 and R5 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; R6 is cyano, trifluoromethyl, or -OR9; R7, R8, and R9 are each independently hydrogen, C1 to C6 alkyl, -(CH2)mR10, C1 to C3 alkylaryl, or aryl; R7 and R8 may be taken together to form a C4-C7 alkyl ring; R10 is cyano, trifluoromethyl, or C1-C4 alkoxy; R11 is hydrogen, -OR12, or -NHCOR12; R12 is C1 to C6 alkyl, aryl, or C1 to C3 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 C1 to C4 alkyl, halogen, hydroxy, cyano, carboxamido, nitro, and C1 to C4 alkoxy, and the pharmaceutically acceptable salts thereof. These compounds are useful psychotherapeutics and are potent serotonin (5-HT1) 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.
