Zusammenfassung: | Derivatives of general formula (1):
in which:
- R1 denotes a linear or branched lower or higher alkoxy group or an optionally substituted amino group,
- R2 denotes a lower alkyl group optionally substituted by an amino group,
- R3 denotes an amino, lower or higher alkoxy, or hydroxyl group provided, however, that at least one amino group is present as R1 or R3
- R4 denotes a hydrogen atom or an aryl group,
- m is equal to 1 or 2,
- n is between 1 and 6,
- Ra and Rb, which are identical or different, denote, when m = 1, a hydrogen atom, when m = 2, a hydrogen atom or an alkyl group.
