GB0516313D0 — Azole derivatives and their uses

USPTO Abstract

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) R 1 is C 1 -C 6 -alkyl or hydrogen; and R 2 is hydrogen or a group -R 7 , -Z-Y-R 7 , -Z-NR 9 R 10 ; -Z-CO-NR 9 R 10 , -Z-NR 9 -C(O)O-R 7 , or -Z-C(O)-R 7 ; and R 3 is a lone pair, or C 1 -C 6 -alkyl; or (ii) R 1 and R 3 together with the nitrogen to which they are attached form a heterocycloalkyl ring, and R 2 is a lone pair or a group -R 7 , -Z-Y-R 7 , -Z-NR 9 R 10 , -Z-CO-NR 9 R 10 , -Z-NR 9 -C(O)O-R 7 ; or; -Z-C(O)-R 7 ; or (iii) R 1 and R 2 together with the nitrogen to which they are attached form a heterocycloalkyl ring, said ring being substituted by a group -Y-R 7 , -Z-Y-R 7 , -Z-NR 9 R 10 ; -Z-CO-NR 9 R 10 ; -Z-NR 9 -C(O)OR 7 ; or; -Z-C(O)-R 7 ; and R 3 is a lone pair, or C 1 -C 6 -alkyl; R 4 and R 5 are independently selected from the group consisting of aryl, aryl-fused-heterocycloalkyl, heteroaryl, C 1 -C 6 -alkyl, cycloalkyl; R 6 is -OH, C 1 -C 6 -alkyl, C 1 -C 6 -alkoxy, hydroxy-C 1 -C 6 -alkyl, nitrile, a group CONR 8 2 or a hydrogen atom; A is an oxygen or a sulfur atom; X is an alkylene, alkenylene or alkynylene group; R 7 is an C 1 -C 6 -alkyl, aryl, aryl-fused-cycloalkyl, aryl-fused-heterocycloalkyl, heteroaryl, aryl(C 1 -C 8 -alkyl)-, heteroaryl(C 1 -C 8 -alkyl)-, cycloalkyl or heterocycloalkyl group; R 8 is C 1 -C 6 -alkyl or a hydrogen atom; Z is a C 1 -C 16 -alkylene, C 2 -C 16 -alkenylene or C 2 -C 16 -alkynylene group; Y is a bond or oxygen atom; R 9 and R 10 are independently a hydrogen atom, C 1 -C 6 -alkyl, aryl, aryl-fused-heterocycloalkyl, aryl-fused-cycloalkyl, heteroaryl, aryl(C 1 -C 6 -alkyl)-, or heteroaryl(C 1 -C 6 -alkyl)- group; or R 9 and R 10 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.
