nitrogen-containing aromatic ring-NR₃-distribution agent-NR′₃-aromatic ring

the nitrogen-containing aromatic ring represents:

a quinolinyl or isoquinolinyl radical optionally substituted with one or more radicals chosen from among:

N(Ra)(Rb), wherein Ra and Rb are identical or different and represent hydrogen or C1-C4 alkyl radical, and

a short-chain C1-C4 alkoxy or alkyl group,

a quinolinyl or isoquinolinyl radical possessing a nitrogen atom in quaternary form,

or

a pyridinyl radical;

or wherein the nitrogen-containing aromatic ring is replaced by a benzimidinyl radical;

the aromatic ring represents:

a quinolinyl radical optionally substituted with one or more radicals chosen from among:

N(Ra)(Rb), wherein Ra and Rb are identical or different and represent hydrogen or C1-C4 alkyl radical, and

a short-chain C1-C4 alkoxy or alkyl group,

a quinolinyl radical possessing a nitrogen atom in quaternary form,

a benzamidinyl radical,

a pyridinyl radical,

a phenyl ring optionally substituted with a halogen group, C1-C4 alkoxy group, cyano group, carbonylamino group optionally substituted with one or more C1-C4 alkyl groups, guanyl group, C1-C4 alkylthio group, amino group, C1-C4 alkylamino group, C1-C4 dialkylamino group for each alkyl, C1-C4 dialkylamino group for each alkyl in which the alkyl portions together form a C3-C8 ring, nitro group, C1-C4 alkyleneamino group, or C2-C4 alkenyleneamino group, or

a mono- or bi- or tricyclic heterocyclic ring comprising 0 to 2 heteroatoms per ring wherein at least one heteroatom is present in at least one ring that is optionally substituted with one or more C1-C4 alkyl groups, C1-C4 alkylene groups, or C2-C4 alkenylene groups;

R3 and R′3 are identical or different and represent, independently of one another, hydrogen or C1-C4 alkyl radical;

the distribution agent represents:

a diazine group selected from a quinazoline;

wherein the diazine group is optionally substituted with:

an aromatic ring as defined above, or

a radical XR1(R2), where X represents a nitrogen to form NR1R2, a linear or branched C1-C6 alkyl radical to form alkR1R2, an oxygen to form OR1, or a sulfur to form SR1,

wherein R1 and R2, which are identical or different, are chosen from among hydrogen; a C1-C8 alkyl radical optionally substituted with one or more radicals which are identical or different; an aromatic ring as defined above; a quinuclidine radical; a pyrrolidinyl radical which is optionally substituted with an alkyl or phenylalkyl radical where alkyl is C1-C4 alkyl; a piperazinyl radical which is optionally substituted with an alkyl, cycloalkyl or phenylalkyl radical; a morpholinyl radical; a pyridyl radical or a piperidyl radical which are optionally substituted with one or more alkyl or phenylalkyl radicals where alkyl is C1-C4 alkyl; an indazolyl radical; a naphthyl radical; a benzotriazole radical; a pyrimidinyl radical optionally substituted with one or more C1-C4 alkyls; and an acenaphthene radical; or

a radical where X represents N or alkyl, R1 and R2 are as defined above, and R1, R2 and X form a saturated or unsaturated 3- to 6-membered monocyclic or 8- to 10-membered bicyclic radical optionally containing one or two identical or different heteroatoms chosen from N, O or S;

or any salts, isomeric forms, racemates, enantiomers and diastereoisomers thereof.
