Patent ID: 8691982

Claim:
A compound of formula (I) below, or a pharmaceutically acceptable salt thereof: where: R 1 is a (C 1 -C 6 )alkyl group or a (C 3 -C 6 )cycloalkyl group; R 2 is: a (C 1 -C 6 )alkyl group, a (C 3 -C 6 )cycloalkyl group, a (C 1 -C 6 )alkenyl group, a (C 1 -C 6 )fluoroalkyl group, a (C 1 -C 3 )fluoroalkoxy group, or a (C 1 -C 6 )alkoxy(C 1 -C 6 )alkyl group, substituted: (i) with one to three hydroxyl groups, or (ii) with an NR a R b group, where R a and R b are independently a hydrogen atom or a (C 1 -C 3 )alkyl group: or a pyrrolidinylmethyl group substituted with one to three hydroxyl groups; R 9 is: hydrogen, a (C 1 -C 6 )alkyl group, a (C 3 -C 6 )cycloalkyl group, a (C 1 -C 6 )alkenyl group, a (C 1 -C 6 )fluoroalkyl group, a (C 1 -C 3 )fluoroalkoxy group, or a (C 1 -C 6 )alkoxy(C 1 -C 6 )alkyl group, substituted: (i) with one to three hydroxyl groups, or (ii) with an NR a R b group; or a pyrrolidinylmethyl group substituted with one to three hydroxyl groups; said R 2 group and R 9 group independently being optionally substituted with an —OCOR 3 group, in which R 3 is a natural or unnatural amino acid group or a piperidyl group of formula (B): where: R 4 is a hydrogen, a halogen atom, a (C 1 -C 3 )alkyl group, a hydroxy(C 1 -C 3 )alkyl group or an —NR a R b group; and R 5 is a hydrogen, a (C 1 -C 3 )alkyl group, an —N(Me) 2 group, a piperidyl group or a morpholinyl group; alternatively, R 2 and R 9 together form, with the nitrogen atom which bears them, a heterocycle selected from the group consisting of a pyrrolidin group, a piperidinyl group, a piperazinyl group, and a piperidinylpiperidiny group, the heterocycles optionally being substituted with one to three groups selected from the group consisting of: hydroxyl; and (C 1 -C 6 )alkyl or (C 1 -C 6 )alkoxy(C 1 -C 6 )alkyl substituted with: (i) one to three hydroxyl groups, or (ii) an NR a R b group; X and Y are independently a phenyl group or a heteroaryl group, said heteroaryl and phenyl groups optionally being substituted with one or two groups independently selected from the group consisting of a (C 1 -C 2 )alkyl group, a (C 1 -C 2 )alkoxy group, a halogen atom, a (C 1 -C 2 )fluoroalkyl group, a (C 1 -C 2 )fluoroalkoxy group, a hydroxyl group, a —COOH group, a —CONHR 6 group, and an —NR a R b group; R 6 is a hydrogen or a (C 1 -C 3 )alkyl, group and said heteroaryl group is selected from the group consisting of a thienyl group, a pyridyl group, a pyrimidinyl group, a thiazolyl group, a pyrrolyl group, and a furanyl group.
