| abstract |
The present invention relates to compounds of formula (I), which may exist in base or acid addition salt state. <Formula I> Wherein R 2 represents a hydrogen or fluorine atom or a hydroxyl, cyano, trifluoromethyl, C 1-6 -alkyl, C 1-6 -alkoxy or NR 8 R 9 group; m, n, o and p are independently a number from 0 to 3, provided that m + n ≦ 7 and o + p ≦ 7; A is a covalent bond, an oxygen atom, a C 1-6 -alkylene group or an -OC 1-6 -alkylene group, the terminal being an oxygen atom in the -OC 1-6 -alkylene group which is bonded to the group R 1 group and is alkyl The end of the lene group is bonded to the carbon of the bicyclic compound; R 1 is an optionally substituted aryl or heteroaryl group; R 3 is hydrogen or a fluorine atom or a C 1-6 -alkyl or trifluoromethyl group; R 4 is an optionally substituted 5-membered heterocyclic compound. The present invention can be used for treatment. |
