abstract |
The invention relates to compounds of formula (I) for treating for example sexual dysfunction, wherein R 1 is optionally substituted C 1-6 alkyl, optionally substituted carbocyclyl, optionally substituted heterocyclyl, hydrogen, C 1-6 alkoxy, —NR 2 R 3 or —NR 4 SO 2 R 5 ; X is the linkage —(CH 2 ) n — or —(CH 2 ) q —O— (wherein Y is attached to the oxygen); wherein one or more hydrogen atoms in linkage X may be replaced independently by C 1-4 alkoxy; hydroxy; hydroxy(C 1-3 alkyl); C 3-7 cycloalkyl; carbocyclyl; heterocyclyl; or by C 1-4 alkyl optionally substituted by one or more fluoro or phenyl groups; n is 3, 4, 5, 6 or 7; and q is 2, 3, 4, 5 or 6; and Y is phenyl or pyridyl, each of which may be substituted; or two R 8 groups on adjacent carbon atoms together with the interconnecting carbon atoms may form a fused optionally substituted 5 - or 6 -membered carbocyclic or heterocyclyic ring. |
