A compound corresponding to general formula (I);

• ##STR57## in which R.sub.1 represents an amino residue corresponding to formula (i):
• ##STR58## in which n represents an integer between 1 and 5, R.sub.4 represents a hydrogen, a linear or branched alkyl group comprising from 1 to 6 carbon atoms or a (CH.sub.2).sub.m OR' group in which m represents an integer between 1 and 5, and R' is a linear or branched alkyl group comprising from 1 to 6 carbon atoms,
• R.sub.5 represents a hydrogen, or a linear or branched alkyl group comprising from 1 to 6 carbon atoms,
• R.sub.2 represents hydrogen, or R.sub.1 and R.sub.2, taken together, form a ring with 6 carbon atoms substituted with an amine functional group (NR.sub.4 R.sub.5) where R.sub.4 and R.sub.5 are as defined above,
• R.sub.3 represents hydrogen, an alkyl residue comprising from 1 to 5 carbon atoms or an aromatic group,
• X may be omitted or may represent either a linear or branched alkyl chain comprising from 1 to 8 carbon atoms or an aromatic group or alternatively an arylalkyl group comprising from 1 to 10 carbon atoms which may be substituted at various positions with a linear or branched alkyl group comprising from 1 to 6 carbon atoms, an oxygen atom, an aryl group, a halogen atom, an alcohol group, an ether group, an ester group, a nitrile group, a nitro group, a ketone group, a thiol group, a thioether group, and an amine group, and
• Y represents NHSO.sub.2 R'.sub.6, where R'.sub.6 represents a linear or branched alkyl chain from 1 to 8 carbon atoms, a cycloalkyl from 4 to 10 carbon atoms, an aromatic residue which are variously substituted, and salts, hydrates, solvates, tacemates and bioprecursors thereof.
