Claim Text:
1. A method of treating a α-chemokine-mediated disease, the method comprising administering an effective amount of a disubstituted 3,4-diamino-3-cyclobutene-1,2-dione compound according to general formula (I) below, or a pharmaceutical composition comprising the compound to an individual subject in need thereof, in which, R1 represents a hydrogen atom or a methyl, R2 represents a ring comprising four atoms, chosen from the structures (1) and (2) below: in which R5 and X have the meaning given hereinafter, R3 represents an aromatic or heteroaromatic ring selected from the group consisting of the rings corresponding to formulae (a) to (o) below: in which R7, R7a, Y and Z have the meaning given hereinafter, it being specified that the rings (a) to (o) can optionally bear several R7 groups, which may be identical or different, the total number of such R7 groups being at most equal to the number of substitutable atoms of the ring; R4 represents an aromatic or heteroaromatic ring selected from the group consisting of the rings corresponding to formulae (p) to (z) and (aa) to (ak) below: in which R7, R8, R9, R10, R11, R12, R13, R14 and R15 have the meaning given hereinafter, R5 represents a hydrogen atom, a fluorine atom, an alkyl radical having from 1 to 5 carbon atoms or a fluoroalkyl or perfluoroalkyl radical comprising from 1 to 5 carbon atoms, R6 represents a hydrogen atom, a —COOtBu radical or a —COOBn radical, R7 represents a radical R16, a halogen, —CF R7a represents a hydrogen atom or else an alkyl radical having from 1 to 5 carbon atoms, R8 represents a hydrogen atom, a halogen atom, or an —OH, —SH, —CONHOR16, —CONR16OH, —NR16R17, —SO R9, R10, R11 and R12 are identical or different and are independently chosen from the group consisting of a hydrogen, a halogen atom and an alkyl, alkoxy, —CF or alternatively, when two of the R9, R10, R11 and R12 radicals are in the ortho position on an aromatic or heteroaromatic ring selected from the group consisting of the rings corresponding to formulae (p) to (z) and (aa) to (ak) above, then they can together form, with the bond which links them together, an aryl, heteroaryl, cycloalkyl or heterocycloalkyl ring, R13 and R14 are identical or different and are independently chosen from the group consisting of a hydrogen atom, a halogen atom, an alkyl, —CF R15 represents a hydrogen atom or an —OH, —SO R16 and R17 are identical or different and are independently selected from the group consisting of a hydrogen atom, one of the following radicals: aryl, heteroaryl, arylalkyl, heteroarylalkyl, alkyl, fluoroalkyl having from 1 to 5 carbon atoms, cycloalkyl or cycloalkylalkyl, and a —CH or alternatively, when R16 and R17 are borne by the same nitrogen atom, they form a heterocycle having between 3 and 7 ring members and optionally comprising one or two heteroatoms chosen from oxygen, sulfur and nitrogen in addition to the common nitrogen atom by which they are borne, it being possible for said heterocycle to be substituted with an alkyl group having from 1 to 5 carbon atoms or a —COOR18 group in which R18 represents an alkyl radical having from 1 to 5 carbon atoms; X represents an oxygen atom, a sulfur atom, or a nitrogen atom substituted with an R6 radical, Y represents an oxygen atom, a sulfur atom, or a nitrogen atom substituted with an R15 radical, and Z represents a carbon or nitrogen atom.
