Mono-and disubstituted 3-propyl gamma-aminobutyric acids

Novel N-substituted azacycloalkyl ring fused 2,3-quinoxalinediones represented by the formula:

Glutamate (ampa/kainate) receptor antagonists: N-substituted fused azacycloalkylquinoxalinediones

Substituted phenols as novel calcium channel blockers

Novel N-substituted azacycloalkyl ring fused 2,3-quinoxalinediones are disclosed represented by the formula: ##STR1## or a pharmaceutically acceptable salt thereof, wherein R.sup.1 is hydrogen, alkyl or W-alkyl; X and Y are independently hydrogen, halogen, nitro, cyano, trifluoromethyl, SO.sub.2 CF.sub.3, SO.sub.2 R.sup.4, SO.sub.2 NR.sup.4 R.sup.5, alkyl, alkenyl, (CH.sub.2).sub.z CONR.sup.4 R.sup.5, (CH.sub.2).sub.z COOR.sup.4, or NHCOR.sup.4, wherein R.sup.4 and R.sup.5 are independently hydrogen, alkyl having 1 to 6 carbon atoms, cycloalkyl or W-alkyl, and z is an integer from 0 to 4; R.sup.2 is benzoyl, W, W-alkyl, COcycloalkyl, COalkyl-W, CONR.sup.3 alkyl, CONR.sup.3 -W, CONR.sup.3 alkyl-W, CSNR.sup.3 alkyl, CSNR.sup.3 alkyl-W, ##STR2## or a moiety derived from a common amino acid by removal of the --OH from the carboxyl group which is alpha to the amino, wherein --W is aryl, heteroaryl, or the heterocycles piperidinyl, piperazinyl, morpholinyl or pyrrolidinyl, wherein R.sup.3 is hydrogen, alkyl or W-alkyl; and m and n are independently 0, 1 or 2 provided that m+n is &gt;1; provided that when R.sup.2 is benzoyl, ##STR3## or X is nitro, Y and R.sup.1 are H, m is 2 and n is 1; when R.sup.2 is ##STR4## X is nitro, Y and R.sup.1 are H and m is 2 and n is 1; or when R.sup.2 is ##STR5## X is bromo, Y and R.sup.1 are H, m is 1 and n is 2. The novel N-substituted azacycloalkyl ring fused 2,3-quinoxalinediones may be used, for example, as neuroprotective agents, for treatment of chronic neurodegenerative disorders, as anticonvulsants and in the treatment of schizophrenia, epilepsy, anxiety, pain and drug addiction.
