Patent ID: 7091350

Claim:
A diaminopyrazole compound having the following structure (I), and the physiologically acceptable salts thereof: wherein: R 1 is chosen from linear and branched C 1 –C 6 alkyl groups and linear and branched C 2 –C 6 alkenyl groups, comprising at least one substituent chosen from OR, C 1 –C 4 alkoxy, NRR′, SR, SOR, SO 2 R, COOR, CONRR′, PO(OH) 2, SO 3 X, NHCONRR′, a non-cationic heterocycle, an aryl group and a halogen; R 2 and R 3, which may be identical or different, are other than H and are chosen from linear and branched, substituted and unsubstituted C 1 –C 6 alkyl and C 2 –C 6 alkenyl groups, wherein R 2 and R 3 may form with the nitrogen atom to which they are attached a saturated or unsaturated, at least 4-membered heterocycle, optionally comprising at least one further hetero atom chosen from N, O and S, wherein R 2, R 3 or said heterocycle optionally being substituted with at least one substituent chosen from OR, NRR′, SR, SOR, SO 2 R, COOR, CONRR′, PO(OH) 2, SO 3 X, NHCONRR′, a non-cationic heterocycle, an aryl group and a halogen, and said heterocycle optionally being substituted with at least one substituent further chosen from CHO, phenyl, and saturated or unsaturated 5- or 6-membered heterocycles comprising at least one hetero atom, wherein R and R′, which may be identical or different, are chosen from a hydrogen atom, a linear and branched C 1 –C 6 alkyl group optionally substituted with OH, a linear and branched C 2 –C 6 alkenyl group, and a C 1 –C 4 alkoxy group substituted with a substituent chosen from OH and NR″R′″, where R″ and R′″, which may be identical or different, are chosen from hydrogen and a C 1 –C 4 alkyl group; or R and R′ may form, with the nitrogen atom to which they are attached, an at least 4-membered heterocycle optionally comprising at least one additional hetero atom chosen from O, N and S, wherein R, R′ and said at least 4-membered heterocycle are unsubstituted or substituted; and X is chosen from a hydrogen atom, alkali metal atoms, alkaline-earth metal atoms, and ammonium groups.
