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 >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.
揭示了由以下公式表示的新型N-取代的环状氮杂环烷环融合的2,3-喹啉二酮,或其药学上可接受的盐:##STR1##其中,R1是氢、烷基或W-烷基;X和Y分别是氢、卤素、硝基、氰基、三氟甲基、SO2CF3、SO2R4、SO2NR4R5、烷基、烯基、(CH2)zCONR4R5、(CH2)zCOOR4或NHCOR4,其中,R4和R5分别是氢、具有1至6个碳原子的烷基、环烷基或W-烷基,z是从0到4的整数;R2是苯甲酰基、W、W-烷基、CO环烷基、CO烷基-W、CONR3烷基、CONR3-W、CONR3烷基-W、CSNR3烷基、CSNR3烷基-W、##STR2##或者是通过去除与氨基相邻的羧基上的-OH而来自常见氨基酸的基团,其中-W是芳基、杂芳基或杂环戊二烯基、哌啶基、哌嗪基、吗啉基或吡咯烷基,其中R3是氢、烷基或W-烷基;m和n独立地是0、1或2,但要求m+n>1;当R2是苯甲酰基、##STR3##或X是硝基、Y和R1是H、m是2而n是1时;当R2是##STR4##时,X是硝基、Y和R1是H,m是2而n是1;或当R2是##STR5##时,X是溴、Y和R1是H,m是1而n是2。这种新型的N-取代的环状氮杂环烷环融合的2,3-喹啉二酮可以用作神经保护剂,用于慢性神经退行性疾病的治疗,作为抗癫痫药物,并用于治疗精神分裂症、癫痫、焦虑、疼痛和药物成瘾。
