Tetrahydroquinoline derivatives

Abstract

The present invention relates to tetrahydroquinoline derivatives having gene formula (I) or a pharmaceutically acceptable salt thereof, wherein R1 and R2 are H or Me; R3 is H, hydroxy, (1-4C)alkoxy, (di)(1-4C)alkylamino(2-4C)alkoxy or (2-6)heterocycloakl(2-4C)alkoxy; R4 is H, OH, (1-4C)alkoxy or R7; R5 is H, OH, (1-4C)alkoxy or R7, with the proviso that if R4 is H, R5 is not H, OH or (1-4C)alkoxy and that if R5 is H, R4 is not H, OH or (1-4C)alkoxy; R6 is (2-5C)heteroaryl, (6C)aryl, (3-8C)cycloalkyl, (2 6C)heterocycloalkyl or (1-6C)alkyl; R7 is amino, (di)(1-4C)alkylamino, (6C)arylcarbonylamino, (6C)arylcarbonyloxy, (2-5C) heteroarylcarbonylamino, (2-5C)heteroarylcarbonyloxy, R8-(2-4C)alkylamino, R8-(2-4C)alkoxy, R9-methylamino or R9-methoxy; R8 is hydroxy, amino, (-14C)alkoxy, (di)(1-4C)alkylamino, (2-6C)heterocycloalkyl, (2-6C) heterocycloalkylcarbonylamino, (di)(1-4C)alkylaminocarbonylamino, (1-4C)alkoxycarbonylamino and R9 is aminocarbonyl, (di)(1-4C)alkylaminocarbonyl, (2-5C)heteroaryl or (6C)aryl. The present invention also relates to pharmaceutical compositions comprising said derivatives and the use of these derivatives to regulate fertility.
