Claim:
A compound of the following general formula (I): or a pharmaceutically acceptable salt thereof, an isomer or a mixture of isomers in all proportions, in which: R 1 represents a hydrogen atom or a linear or branched C 1 to C 6 alkyl, linear or branched C 2 to C 6 alkenyl, linear or branched C 2 to C 6 alkynyl, aryl or arylalkyl group, R 2 represents a hydrogen atom, a saturated or unsaturated 3- to 7-membered hydrocarbon cycle, a 3- to 7-membered heterocycle or a linear or branched C 1 to C 6 alkyl, linear or branched C 2 to C 6 alkenyl, linear or branched C 2 to C 6 alkynyl, optionally substituted aryl, optionally substituted arylalkyl, C(O)R′, SO 2 —R′, C(O)OR′, C(O)NHR′, NH═CNHR′, C(═NR′″)R′, C(S)R′, C(S)OR′, or C(S)NHR′ group, where R′ and R′″ represent, independently of each other, a hydrogen atom, a saturated or unsaturated 3- to 7 membered hydrocarbon cycle, an optionally substituted 3- to 7-membered heterocycle, a linear or branched C 1 to C 6 alkyl, linear or branched C 2 to C 6 alkenyl, linear or branched C 2 to C 6 alkynyl, C 1 to C 6 hydroxyalkyl, C 1 to C 6 aminoalkyl, polyamine, polyether, optionally substituted aryl, optionally substituted arylalkyl or optionally substituted heteroaryl group, or R 1 and R 2 form together, with the nitrogen atom bearing them, an optionally substituted heteroaryl or a 3- to 7-membered heterocycle, which can comprise 1 to 3 additional heteroatoms, and optionally substituted with a linear or branched C 1 to C 6 alkyl, linear or branched C 2 to C 6 alkenyl, linear or branched C 2 to C 6 alkynyl, aryl, arylalkyl or heteroaryl group, R 3 , R 4 , R 5 and R 6 represent, independently of each other, a hydrogen atom, a saturated or unsaturated 3- to 7-membered hydrocarbon cycle or a SO 3 H, PO 3 H 2 , C(O)OH, C(O)R″, C(O)OR″, C(O)NHR″, C(S)R″, C(S)OR″, C(S)NHR″ group, where R″ represents a hydrogen atom; a saturated or unsaturated 3- to 7-membered hydrocarbon cycle; a 3- to 7-membered heterocycle optionally substituted with a linear or branched C 1 to C 6 alkyl; a linear or branched C 1 to C 6 alkyl; linear or branched C 2 to C 6 alkenyl; linear or branched C 2 to C 6 alkynyl; C 1 to C 6 hydroxyalkyl; C 1 to C 6 aminoalkyl; optionally substituted polyamine; polyether; optionally substituted aryl; or optionally substituted heteroaryl group, or R 3 and R 1 together form a —CR 8 R 9 —, —SO 2 — or —PO 2 H— chain binding the oxygen atoms bearing them, R 7 represents a hydrogen atom, a linear or branched C 1 to C 6 alkyl, linear or branched C 2 to C 6 alkenyl or linear or branched C 2 to C 6 alkynyl group or a saturated or unsaturated 3- to 7-membered hydrocarbon cycle, and R 8 and R 9 represent, independently of each other, a hydrogen atom or a linear or branched C 1 to C 6 alkyl group, such as a methyl.
