摘要

The invention relates to novel derivatives of 14,15-dihydro 20,21 dinoreburnamenin-14-ol, having formula (I), in which R represents a radical -AR', wherein A represents a heteroatom and R' represents a group selected from the group comprising alkyl radicals at C1-C6, alkenyls at C1-C6, alkynyls at C1-C6, aralkyls; esters having formula -R1-CO-O-R2; amides having formula -R3-CO-NZY, wherein Y and Z together can form a cycloalkyl radical or a heterocyclic radical, optionally substituted by one or more alkyl radicals; a radical selected from the group comprising alkyl radicals, alkenyls or alkynyls, substituted by at least one amine having formula -NZY; or one of the pharmaceutically-acceptable salts thereof, including the isomers, enantiomers and diastereoisomers thereof and mixtures of same. The invention also relates to the use of said novel derivatives for the preparation of a pharmaceutical composition which is intended, in particular, for the treatment and/or prevention of depression, sleep/wake cycle disorders and symptomatic frontal disorders in cognitive components among humans.
