Compounds of general formula (I) wherein each of R?1 and R2¿ independently represents a C¿1-6? alkyl or C2-7 acyl group; R?5¿ represents a hydrogen atom or a C¿1-3? alkyl, C2-3 alkenyl or C2-3 alkynyl group; R?6¿ represents a hydrogen atom or a C¿1-6? alkyl, C2-6 alkenyl, C2-6 alkynyl, amino, C1-6 alkylamino, di(C1-6) alkylamino or C2-7 acylamino group; each of R?7 and R8¿ independently represents a hydrogen or halogen atom or a hydroxy, trifluoromethyl, C¿1-6? alkyl, C2-6 alkenyl, C2-6 alkynyl, C2-7 acyl, C1-6 alkythio, C1-6 alkoxy, C3-6 cycloalkyl; and R?9¿ represents a hydrogen or halogen atom or a hydroxy, trifluoromethyl, C¿1-6? alkyl, C2-6 alkenyl, C2-6 alkynyl, C2-7 acyl, C1-6 alkythio, C1-6 alkoxy or C3-6 cycloalkyl group; X represents OCH2 or a group CR?3R4¿, wherein each of R?3 and R4¿ independently represents a hydrogen atom or a C¿1-3? alkyl group; each of R?10 and R11¿ independently represents a hydrogen atom, a C¿1-3? alkyl, C3-6 cycloalkyl or phenyl group; y represents an oxygen atom or a group CHNO2, NCN, NH or NNO2, n is an integer from 2 to 4; or a salt thereof; are useful for treatment of respiratory disorders such as asthma. Compounds of the invention have a longer duration of action than the known compound trequinsin (9, 10-dimethoxy-3-methyl-2-mesitylimino-2,3,6,7-tetrahydro-4H-pyrimido[6,1-a]isoquinolin-4-one) and do not have trequinsin's very bitter taste.
通式(I)的化合物其中R1和R2分别独立地表示C1-6烷基或C2-7酰基基团;R5表示氢原子或C1-3烷基,C2-3烯基或C2-3炔基基团;R6表示氢原子或C1-6烷基,C2-6烯基,C2-6炔基,氨基,C1-6烷基氨基,双(C1-6)烷基氨基或C2-7酰基氨基基团;R7和R8分别独立地表示氢或卤原子或羟基,三氟甲基,C1-6烷基,C2-6烯基,C2-6炔基,C2-7酰基,C1-6烷硫基,C1-6烷氧基,C3-6环烷基;R9表示氢或卤原子或羟基,三氟甲基,C1-6烷基,C2-6烯基,C2-6炔基,C2-7酰基,C1-6烷硫基,C1-6烷氧基或C3-6环烷基基团;X表示OCH2或CR3R4基团,其中R3和R4分别独立地表示氢原子或C1-3烷基基团;R10和R11分别独立地表示氢原子,C1-3烷基,C3-6环烷基或苯基;y表示氧原子或CHNO2,NCN,NH或NNO2基团,n为2到4的整数;或其盐;用于治疗哮喘等呼吸系统疾病。与已知化合物trequinsin(9,10-二甲氧基-3-甲基-2-二苯基亚胺-2,3,6,7-四氢-4H-嘧啶[6,1-a]异喹啉-4-酮)相比,本发明化合物具有更长的作用时间,并且不具有trequinsin非常苦的味道。
