    摘要： The invention provides compounds of formula (I) and the pharmaceutically acceptable salts thereof, wherein R is a 5-membered ring heteroaryl group containing 3 or 4 nitrogen heteroatoms which is linked to the quinoxalinedione ring by a ring carbon or nitrogen atom, or is a 6-membered ring heteroaryl group containing from 1 to 3 nitrogen heteroatoms which is linked to the quinoxalinedione ring by a ring carbon atom, either of said groups being optionally benzo-fused and optionally substituted, including in the benzo-fused portion, by 1 or 2 substituents each independently selected from C1-C4 alkyl, C2-C4 alkenyl, C3-C7 cycloalkyl, halo, hydroxy, C1-C4 alkoxy, C3-C7 cycloalkyloxy, -COOH, C1-C4 alkoxycarbonyl, -CONR?3R4, -NR3R4¿, -S(O)¿p?(C1-C4 alkyl), -SO2NR?3R4¿, aryl, aryloxy, aryl(C¿1?-C4)alkoxy and het, said C1-C4 alkyl being optionally substituted by C3-C7 cycloalkyl, halo, hydroxy, C1-C4 alkoxy, halo(C1-C4)alkoxy, C3-C7 cycloalkyloxy, C3-C7 cycloalkyl(C1-C4)alkoxy, -COOH, C1-C4 alkoxycarbonyl, -CONR?3R4, -NR3R4¿, -S(O)¿p?(C1-C4 alkyl), -SO2(aryl), -SO2NR?3R4¿, morpholino, aryl, aryloxy, aryl(C¿1?-C4)alkoxy or het, and said C2-C4 alkenyl being optionally substituted by aryl; R?1 and R2¿ are each independently selected from H, fluoro, chloro, bromo, C¿1?-C4 alkyl and halo(C1-C4)alkyl; R?3 and R4¿ are either each independently selected from H and C¿1?-C4 alkyl or, when taken together, are C5-C7 alkylene; p is 0, 1 or 2; together with the preparation of, compositions containing, the uses of and intermediates used in the synthesis of, such compounds. The compounds are useful as NMDA receptor antagonists for treating acute neurodegenerative and chronic neurological disorders.
