Patent ID: 7034021

Claim:
A compound of general formula (I): in which: R1, R2, are chosen independently from the groups: H, (C1-C20)alkyl wherein R3, R4, are chosen independently from the groups: H 1 (C 1 -C 20 ) alkyl (C 2 -C 20 ) alkenyl R3 and R4 can form with the nitrogen atom an n-membered ring (n between 3 and 8) optionally comprising one or more heteroatoms chosen from N, O, S, R5 and R6 are chosen independently from the groups: H, (C1-C20)alkyl optionally substituted with hydroxyl, (C3-C8)cycloalkyl optionally substituted with (C6-C14)aryl (C1-C5) alkoxy, (C3-C8)heterocycloalkyl carrying one or more heteroatoms chosen from N, O, S, (C6-C14)aryl optionally substituted with hydroxyl, (C1-C13)heteroaryl carrying one or more heteroatoms chosen from N, O, S, (C6-C14) aryl (C1-C5)alkyl, wherein R5 and R6 can form with the carbon atom to which they are attached an m-membered ring (m between 3 and 8 ) optionally comprising one or more heteroatoms chosen from N, O, S and being capable of being substituted with hydroxyl, (C1-C5)alkyl, (C6-C14)aryl (C1-C5)alkoxy, wherein when R1 and R2 represent a hydrogen, or R3 and R4 represent a hydrogen, then R3 and R4 or R1 and R2 are defined as above with the exception of hydrogen, or its tautomeric, enantiomeric, diastereoisomeric and epimeric form or the pharmaceutically acceptable salt thereof.
