5-arylindole derivatives

Abstract

Compounds of formula (I), wherein A, B, D, E, and F are each independently nitrogen or carbon; R.sub.1 is hydrogen, C.sub.1 to C.sub.6 alky, --(CH.sub.2).sub.n R.sub.7, or C.sub.1 to C.sub.3 alkyl-aryl; R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are each independently hydrogen, C.sub.1 to C.sub.6 alkyl, aryl, C.sub.1 to C.sub.3 alkyl-aryl, halogen, cyano, nitro, --(CH.sub.2).sub.m NR.sub.8 R.sub.9, --(CH.sub.2).sub.m OR.sub.9, --SR.sub.9, --SO.sub.2 NR.sub.8 R.sub.9, --(CH.sub.2).sub.m NR.sub.8 SO.sub.2 R.sub.9, --(CH.sub.2).sub.m NR.sub.8 CO.sub.2 R.sub.9, --(CH.sub.2 .sub.m NR.sub.8 COR.sub.9, --(CH.sub.2).sub.m CONR.sub.7 R.sub.9, or --(CH.sub.2).sub.m CO.sub.2 R.sub.9 ; R.sub.2 and R.sub.3, R.sub.3 and R.sub.4, R.sub.4 and R.sub.5, and R.sub.5 and R.sub.6 may be taken together to form a 5- to 7-membered alkyl ring, a 6-membered aryl ring, a 5- to 7-membered heteroalkyl ring, having 1 heteroatom of N, O, or S, or a 5- to 6-membered heteroaryl ring having 1 or 2 heteroatoms of N, O, or S; R.sub.7 is --OR.sub.10 , --SR.sub.10, --SO.sub.2 NR.sub.10 R.sub.11, --NR.sub.10 SO.sub.2 R.sub.11, --NR.sub.10 CO.sub.2 R.sub.11, --NR.sub.10 COR.sub.11, --CONR.sub.10 R.sub.11, or --CO.sub.2 R.sub.10 ; R.sub.8, R.sub.9, R.sub.10 and R.sub.11 are each independently hydrogen, C.sub.1 to C.sub.6 alkyl, or C.sub.1 to C.sub.3 alkyl-aryl; m is 0, 1, or 2; n is 2, 3, or 4; and the above aryl groups and the aryl moieties of the above alkyl-aryl groups are each independently phenyl or substituted phenyl, where said substituted phenyl may be substituted with 1 to 3 of C.sub.1 to C.sub.4 alkyl, halogen, hydroxy, cyano, carboxamido, nitro, or C.sub.1 to C.sub.4 alkoxy, and the pharmaceutically acceptable salts thereof. These compounds are useful in treating migraine and other disorders and are new. 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 hermicrania and headache associated with vascular disorders, and other disorders arising from deficient serotonergic neurotransmission. The compounds can also be used as centrally acting antihypertensives and vasodilators.
