Claim:
A compound of formula (1) or a pharmaceutically acceptable salt, a stereoisomer, a racemate, or a mixture of diastereoisomers, wherein: R 1 is chosen from H, alkyl(1-6C), alkyl(1-3C)cycloalkyl(3-6C), carbalkoxy(2-7C) and acyl(2-7C); [ ] m symbolizes —(CH 2 ) m — wherein m is 0; R 2 is chosen from halogen, CF 3 , alkyl(1-6C), alkyl(1-3C)cycloalkyl(3-6C), phenyl, amino aminoalkyl(1-3C), alkyl(1-3C)amino, dialkyl(1-3C)amino, cyano, cyanoalkyl(1-3C), hydroxy, hydroxyalkyl(1-3C), (1-3C)alkoxy, OCF 3 , acyl(2-7C), trifluoroacetyl, aminocarboxyl, (1-3C)alkylsulfonyl and trifluoromethyl sulphonyl, and n is an integer ranging from 0 to 4, with the proviso that when n is 2, 3 or 4, the R 2 substituents may be either the same or different; A is chosen from saturated and partially unsaturated rings; [ ] o and [ ] p symbolize —(CH 2 ) o — and —(CH 2 ) p — respectively, with the proviso that —CH— is possible when A is a partially unsaturated ring, and o and p independently are chosen 1; R 3 , R 4 , R 5 and R 6 , which are different or identical, are chosen from hydrogen, alkyl(1-3C), alkyl(1-3C)cyclo-alkyl(3-6C), CH 2 OH, and (R 3 and R 5 ) or (R 3 and R 6 ) or (R 4 and R 5 ) or (R 4 an R 6 ) together can form an alkylene bridge of 1 to 3 carbon atoms; and R 7 is chosen from H, halogen, CF 3 , alkyl(1-6C), alkyl(1-3C)cycloalkyl(3-6C), amino aminoalkyl(1-3C), alkyl(1-3C)amino, dialkyl(1-3C)amino, hydroxy, hydroxyalkyl(1-3C), (1-3C)alkoxy, OCF 3 , acyl(2-7C), aminocarboxyl, and (1-3C) alkylsulfonyl.
