Pharmaceutical compositions for inhalation comprising compounds of formula (I) are useful in the treatment of diseases where enhanced M3 receptor activation is implicated, such as respiritory tract diseases:
wherein (i) R1 is C1-C6-alkyl or hydrogen; and R2 is hydrogen or a group -R7, -Z-Y-R7,
-Z-NR9R10; -Z-CO-NR9R10, -Z-NR9-C(O)O-R7, or -Z-C(O)-R7; and R3 is a lone pair, or C1-C6-alkyl; or (ii) R1 and R3 together with the nitrogen to which they are attached form a heterocycloalkyl ring, and R2 is a lone pair or a group -R7, -Z-Y-R7, -Z-NR9R10,
-Z-CO-NR9R10, -Z-NR9-C(O)O-R7; or; -Z-C(O)-R7; or (iii) R1 and R2 together with the nitrogen to which they are attached form a heterocycloalkyl ring, said ring being substituted by a group -Y-R7, -Z-Y-R7, -Z-NR9R10; -Z-CO-NR9R10; -Z-NR9-C(O)OR7; or; -Z-C(O)-R7; and R3 is a lone pair, or C1-C6-alkyl; R4 and R5 are independently selected from the group consisting of aryl, aryl-fused-heterocycloalkyl, heteroaryl, C1-C6-alkyl, cycloalkyl; R6 is -OH, C1-C6-alkyl, C1-C6-alkoxy, hydroxy-C1-C6-alkyl, nitrile, a group CONR82 or a hydrogen atom; A is an oxygen or a sulfur atom; X is an alkylene, alkenylene or alkynylene group; R7 is an C1-C6-alkyl, aryl, aryl-fused-cycloalkyl, aryl-fused-heterocycloalkyl, heteroaryl, aryl(C1-C8-alkyl)-, heteroaryl(C1-C8-alkyl)-, cycloalkyl or heterocycloalkyl group; R8 is C1-C6-alkyl or a hydrogen atom; Z is a C1-C16-alkylene, C2-C16-alkenylene or C2-C16-alkynylene group; Y is a bond or oxygen atom; R9 and R10 are independently a hydrogen atom, C1-C6-alkyl, aryl, aryl-fused-heterocycloalkyl, aryl-fused-cycloalkyl, heteroaryl, aryl(C1-C6-alkyl)-, or heteroaryl(C1-C6-alkyl)- group; or R9 and R10 together with the nitrogen atom to which they are attached form a heterocyclic ring of 4-8 atoms, optionally containing a further nitrogen or oxygen atom.
由式(I)化合物组成的吸入用药物组合物可用于治疗与 M3 受体激活增强有关的疾病,如呼吸道疾病:
其中 (i) R1 是 C1-C6- 烷基或氢;R2 是氢或基团 -R7、-Z-Y-R7、
-Z-CO-NR9R10,-Z-NR9-C(O)O-R7,或-Z-C(O)-R7;R3 是孤对或 C1-C6-烷基;或 (ii) R1 和 R3 与它们所连接的氮一起形成杂环烷基环,R2 是孤对或基团 -R7,-Z-Y-R7,-Z-NR9R10、
-Z-CO-NR9R10、-Z-NR9-C(O)O-R7;或;-Z-C(O)-R7;或 (iii) R1 和 R2 与它们所连接的氮一起形成杂环烷基环,所述环被基团 -Y-R7、-Z-Y-R7、-Z-NR9R10 取代;-Z-CO-NR9R10;-Z-NR9-C(O)OR7;或;-Z-C(O)-R7;R4 和 R5 独立地选自由芳基、芳基-融合-杂环烷基、杂芳基、C1-C6-烷基、环烷基组成的组;R6 是-OH、C1-C6-烷基、C1-C6-烷氧基、羟基-C1-C6-烷基、腈、基团 CONR82 或氢原子;A 是氧原子或硫原子;X 是亚烷基、烯基或炔基;R7 是 C1-C6 烷基、芳基、芳基-融合环烷基、芳基-融合杂环烷基、杂芳基、芳基(C1-C8-烷基)-、杂芳基(C1-C8-烷基)-、环烷基或杂环烷基;R8 是 C1-C6 烷基或氢原子;Z 是 C1-C16 烯基、C2-C16 烯基或 C2-C16 烯炔基;Y 是键或氧原子;R9 和 R10 独立地为氢原子、C1-C6-烷基、芳基、芳基-熔合杂环烷基、芳基-熔合环烷基、杂芳基、芳基(C1-C6-烷基)- 或杂芳基(C1-C6-烷基)- 基团;或 R9 和 R10 与它们所连接的氮原子一起形成一个 4-8 个原子的杂环,可选地含有另一个氮原子或氧原子。
