Abstract:
A 4,5-diaminopyrazole compound of formula (I): wherein R1 represents hydrogen, a straight-chain or branched C1- to C6-alkyl group, a C1- to C4-hydroxyalkyl group, a C1- to C4-aminoalkyl group, a C1- to C8-alkylamino group, a di(C1- to C8-alkyl)amino group, a C1- to C4-alkylamino-(C1- to C4-alkyl) group, a di(C1- to C4-alkylamino)-C1- to C4-alkyl group or an aryl group; R2 and R3, independently of each other, are the same or different and each represent hydrogen, a straight-chain or branched C1- to C6-alkyl group, an aryl group, a carboxyl group, an alkoxycarbonyl group, an aminocarbonyl group, a hydroxy group or a C1- to C4-hydroxyalkyl group, or R2 and R3 together represent an unsubstituted C1- to C6-alkylene group; Z represents a C1- to C10-alkyl diradical, which is optionally interrupted by an aromatic diradical; or Z is a diradical of formula â€”Ar(Alk)nâ€”Arâ€”, wherein Ar represents an arylene group, Alk represents a â€”CH2â€” group and n represents a number from 0 to 6; and x and y independently of each other represent 0 or 1; or a salt thereof with an organic or an inorganic acid.
