Claim:
A compound chosen from 4-aminoindole derivatives of formula (I) and the addition salts, mesomers, isomers, and solvates thereof: wherein: R 1 is chosen from: hydrogen atoms; and linear and branched saturated C 1 -C 6 alkyl radicals, optionally interrupted with a radical chosen from oxygen atoms and NR 7 radicals, optionally substituted with a radical chosen from OH and NR 7 R 8 ; R 2 and R 3 , which may be identical or different, are chosen from: hydrogen atoms; C 1 -C 6 alkyl radicals, optionally substituted with at least one hydroxyl radical; carboxyl radicals; and radicals CONR 7 R 8 ; R 4 and R 5 , which may be identical or different, are chosen from: hydrogen atoms; and C 1 -C 6 alkyl radicals; R 6 is chosen from: linear and branched C 1 -C 6 alkyl radicals, optionally interrupted with a heteroatom chosen from O and NR 9 radicals, and optionally substituted with at least one radical, which may be identical or different, chosen from OH and NR 7 R 8 ; carboxyl radicals; C 1 -C 10 alkyl carboxylates; radicals CONR 7 R 8 ; C 1 -C 10 (poly)hydroxyalkyloxy radicals; (poly)(C 1 -C 10 )alkoxy(C 1 -C 10 )alkyloxy radicals; —O-Ak-NR 9 R 10 radicals wherein Ak is chosen from linear C 1 -C 8 and branched C 3 -C 8 divalent alkylene radicals, optionally interrupted with at least one oxygen atom and at least one group NR 7 ; R 7 and R 8 , which may be identical or different, are chosen from: hydrogen atoms; C 1 -C 8 alkyl radicals optionally substituted with at least one hydroxyl radical; R 9 and R 10 , which may be identical or different, are chosen from linear and branched, saturated and unsaturated C 1 -C 4 alkyls; R 9 and R 10 may form, with the nitrogen that bears them, a saturated or unsaturated 5- to 8-membered heterocycle, one of the chain members optionally being chosen from oxygen atoms and NR 11 radicals wherein R 11 is chosen from hydrogen atoms and C 1 -C 4 alkyls, optionally substituted with at least one radical chosen from OH and NR 7 R 8 ; with the exception of the two compounds:
