Abstract

Compound of formula (I) wherein W, X, Y, Z is —C(R¹)═ or N; R¹ is hydrogen or alkyl, V is N or C (i.e. carbon), A is a bond or an alkylene linker with 1 to 3 carbon atoms, with the proviso that when A is a bond, V must be CH, R is ethyl, propyl, a branched C_3-6 alkyl or a cyclic C_3-8 alkyl, m and n is 1-3, D is heteroaryl optionally substituted with halogen, hydroxy, cyano, alkyl, cycloalkyl, alkoxy, —(CH₂)₀—(C═O)_p—NR²R³, or D is aryl optionally substituted with one or more of the groups independently selected from hydrogen, halogen, hydroxy, cyano, alkyl, cycloalkyl, haloalkyl, alkoxy, haloalkoxy, alkylsulfonyl, alkylsulfinyl, heterocyclyl, heterocyclylalkyl, heterocyclyl-alkoxy, heterocyclylcarbonyl, alkylcarbonyl, alkoxycarbonyl, alkylcarboxy, cyanoalkyl, hydroxyalkyl, alkoxyalkyl, alkylcarbonylamino, alkylcarbonylaminoalkyl, arylcarbonylamino, aryl-carbonylaminoalkyl, heteroarylcarbonylamino or heteroarylcarbonylaminoalkyl, —(CH₂)₀—(C═O)_p—NR²R³, wherein o is 0-3, p is 0 or 1, and R² and R³ independently are hydrogen, alkyl or cycloalkyl; or R² and R³, can together with the attached nitrogen form a heterocyclyl group, and salts and solvates thereof have binding affinity for the histamine H3 receptor.
