Patent ID: 8604063

Claim:
A compound having the following formula: wherein, X1 represents a nitrogen atom or a NR11 group, with R11 representing a hydrogen atom or a C1 to C3 alkyl group; R1 represents a hydrogen atom, an NR11R12 group, or OR12 group with R11 being defined above and R12 representing a hydrogen atom or a C1 to C3 alkyl group; Y2 represents a nitrogen atom or a CR11 group with R11 selected from the group consisting of a hydrogen atom, a group and a group wherein: R4 represents a hydrogen atom or a C1 to C3 alkyl or a C(═O)NR14R15 group with R4 representing a hydrogen atom or a C1 to C3 alkyl group when R5 or R6 is different than a hydrogen atom; R5 represents a hydrogen atom, a C(═O)NR14R15 group or a group with R5 representing a hydrogen atom, when R4 or R6 is different than a hydrogen atom; R6 represents a hydrogen atom, or a C(═O)NR14R15 group or a group, and with R6 representing a hydrogen atom when R5 is different than a hydrogen atom or when R4 is different than a hydrogen atom or a C1 to C3 alkyl group; and R14 and R15 representing independently of the other: a hydrogen atom, or a linear or branched C1 to C10 alkyl group, wherein one or more carbon atoms can be substituted by a nitrogen atom, said alkyl group optionally being substituted by one or more —OH and/or ═O groups and/or by: which may be substituted or unsubstituted, and R17 represents: a hydrogen atom, or a linear or branched C1 to C3 alkyl group, wherein one or more carbon atoms can be substituted by a nitrogen atom, said alkyl group optionally being substituted by one or more —OH and/or ═O groups; and with Y2 representing a nitrogen atom or a CR11 group with R11 being a hydrogen atom, when R8 or R8′ is different than a nitrogen atom or a CH group and when R8′ is different than a hydrogen or halogen atom; R8 and R8′ represent a hydrogen atom, a halogen atom, a group, or a C(═O)NR18R19 group with R18 and R19 representing independently of the other: a hydrogen atom, or a linear or branched C1 to C3 alkyl group, wherein one or more carbon atoms can be substituted by a nitrogen atom, said alkyl group optionally being substituted by one or more —OH and/or ═O groups and/or by: which may be substituted or unsubstituted, with R8 representing a hydrogen or halogen atom, when Y2 is different than a nitrogen atom or a CH group and when R8′ is different than a hydrogen or halogen atom; and with R8′ representing a hydrogen or halogen atom, when Y2 is different than a nitrogen atom or a CH group and when R8 is different than a hydrogen or halogen atom; R21 and R22 represent independently of the other a hydrogen atom or a methyl group; pharmaceutically acceptable salts of said compounds, stereo isomers thereof and/or mixtures of same.
