Abstract: Compounds of formula (I) are useful in the treatment of diseases where enhanced M3 receptor activation is implicated, such as respiratory 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—[AE11]C(O)O—R7, or —Z—C(O)—R7; and R3 is a lone pair, or C1C6-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—[AE12]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—[AE13]C(O)O—R7; 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, ary-tfused-heterocycloalkyl, heteroaryl, C1-C6-alkyl, cycloalkyl; R6 is —OH, C1-C6-alkyl, C1-C6-alkoxy, hydroxy-C1-C6-alkyl, nitrile, a g

Abstract: Compounds of Formula (I) or pharmaceutically acceptable salts, hydrates, solvates, geometrical isomers, tautomers, optical isomers, or prodrug forms thereof, wherein X, Y, Z, R1, R2, R3 and R4 are as defined herein are capable of binding to the active site of protein kinase enzymes. In particular, they are inhibitors of a serine/threonine kinase more particularly Rho kinase (ROK, ROCK).
