A compound of general formula: wherein R 1 and R 2 independently represent hydrogen; a branched or unbranched, saturated or unsaturated, aliphatic radical C 1-10; a unsubstituted aryl; unsubstituted heteroaryl radical; C 3-9 cycloalkyl radical optionally containing at least one heteroatom as ring member selected from N, O or S and optionally substituted by a C 1-6 alkyl group, a phenyl group, a benzyl group, a linear or branched C 1-6 alkoxy group, -F, -Cl, -I, -Br, -CF 3, -CH 2 F, -CHF 2, -CN, -OH, -SH, -NH 2, oxo, -(C=O)R', - SR', -SOR', -SO 2 R', -NHR', -NR'R" whereby R' and optionally R" for each substitutent independently represents a linear or branched C 1-6 -alkyl group; a cycloalkylalkyl radical C 1-10; an arylalkyl radical C 1-10; or an heteroarylalkyl radical C 1-10; or R 1 and R 2 together with the bridging nitrogen form a C 3-9 cycloalkyl optionally containing at least one additional heteroatom as a ring member selected from N, O or S and optionally substituted by a C 1-6 alkyl group, a linear or branched C 1-6 alkoxy group, -F, -CI, -I, -Br, -CF 3, -CH 2 F, -CHF 2, -CN, -OH, -SH, -NH 2, oxo, - (C=O)R', -SR', -SOR', -SO 2 R', -NHR', -NR'R" whereby R' and optionally R" for each substitutent independently represents a linear or branched C 1-6 -alkyl group or by a group selected from: or R 1 and R 2 together with the bridging nitrogen form C 3-9 cycloalkyl optionally containing at least one additional heteroatom as a ring member selected from N, O or S, which may be condensed to form a ring system with another C 3-9 cycloalkyl optionally containing at least one heteroatom as a ring member selected from N, O or S; or which may be condensed to form a ring system with an aryl radical; or which may be spirofused to an aryl or heteroaryl group; R 3 represents hydrogen or halogen; n is 0, 1 or 2; m is 1, 2, 3 or 4; and ----- represents an optionally double bond; with the proviso that when R 1 and R 2 together with the bridging nitrogen form a piperidine, R 3 is hydrogen and n is 0, m is not 3; or a pharmaceutically acceptable salt, stereoisomer or solvate thereof. R 1 and R 2 independently represent hydrogen; a branched or unbranched, saturated or unsaturated, aliphatic radical C 1-10; a unsubstituted aryl; unsubstituted heteroaryl radical; C 3-9 cycloalkyl radical optionally containing at least one heteroatom as ring member selected from N, O or S and optionally substituted by a C 1-6 alkyl group, a phenyl group, a benzyl group, a linear or branched C 1-6 alkoxy group, -F, -Cl, -I, -Br, -CF 3, -CH 2 F, -CHF 2, -CN, -OH, -SH, -NH 2, oxo, -(C=O)R', - SR', -SOR', -SO 2 R', -NHR', -NR'R" whereby R' and optionally R" for each substitutent independently represents a linear or branched C 1-6 -alkyl group; a cycloalkylalkyl radical C 1-10; an arylalkyl radical C 1-10; or an heteroarylalkyl radical C 1-10; or R 1 and R 2 together with the bridging nitrogen form a C 3-9 cycloalkyl optionally containing at least one additional heteroatom as a ring member selected from N, O or S and optionally substituted by a C 1-6 alkyl group, a linear or branched C 1-6 alkoxy group, -F, -CI, -I, -Br, -CF 3, -CH 2 F, -CHF 2, -CN, -OH, -SH, -NH 2, oxo, - (C=O)R', -SR', -SOR', -SO 2 R', -NHR', -NR'R" whereby R' and optionally R" for each substitutent independently represents a linear or branched C 1-6 -alkyl group or by a group selected from: or R 1 and R 2 together with the bridging nitrogen form C 3-9 cycloalkyl optionally containing at least one additional heteroatom as a ring member selected from N, O or S, which may be condensed to form a ring system with another C 3-9 cycloalkyl optionally containing at least one heteroatom as a ring member selected from N, O or S; or which may be condensed to form a ring system with an aryl radical; or which may be spirofused to an aryl or heteroaryl group; R 3 represents hydrogen or halogen; n is 0, 1 or 2; m is 1, 2, 3 or 4; and ----- represents an optionally double bond; with the proviso that when R 1 and R 2 together with the bridging nitrogen form a piperidine, R 3 is hydrogen and n is 0, m is not 3; or a pharmaceutically acceptable salt, stereoisomer or solvate thereof.
