| abstract |
The invention concerns the use of compounds of general formula (I), wherein: n represents an integer from 1 to 10; R1 and R6, independently of each other, represent a hydrogen atom, a group useful for protecting nitrogen atoms in peptide synthesis or a group of formula COR or -CH2COR, wherein R represents a hydrogen atom, an alkyl group of 1 to 10 carbon atoms, a -COORa group wherein Ra represents H or an alkyl group, a primary -NH2 amino group or a secondary or tertiary amine, an alkoxy group, a phenyl group or a pyridinium group; R2, R3, R4 and R5, independently of one another, represent a hydrogen atom, an alkyl group of 1 to 10 carbon atoms; Y represents CH2 and Z represents CO, or Y represents CO and Z represents CH2, for preparing a medicine for treating tumoral pathologies or neurodegenerative diseases such as Alzheimer's or Lehn's disease. |
