CA 2569662

The invention relates to new peptide fragments capable of stimulating neurite outgrowth, stimulating of cell survival, stimulating neural plasticity associated with memory and learning, and modulating cell motility. The biological activity of the peptide fragments is associated with their capability of binding and activating a neurotrophin receptor of the Trk family. The peptide fragments of the invention comprise an amino acid motif which is essential for binding and activating a neurotrophin receptor of the Trk family. The invention also concerns pharmaceutical compositions comprising the compounds and uses thereof for prevention and/or treatment of conditions and/or diseases, wherein neurotrophing, Tkr receptors and/or NCAM play an important role, and wherein stimulating of neurite outgrowth, cell survival, neural plasticity associated with memory and learning, and/or modulating cell motility is beneficial for treatment.

L'invention concerne de nouveaux fragments peptidiques permettant de stimuler la croissance des neurites, de stimuler la survie cellulaire, de stimuler la plasticité neuronale associée à la mémoire et à l'apprentissage, et de moduler la motilité cellulaire. L'activité biologique de ces fragments peptidiques est associée à leur capacité de se lier à un récepteur de neurotrophine de la famille Trk et de l'activer. Les fragments peptidiques de l'invention comprennent un motif d'acides aminés qui est essentiel pour la liaison à un récepteur de neurotrophine de la famille Trk et pour l'activation de ce récepteur. L'invention concerne également des compositions pharmaceutiques comprenant ces composés ainsi que leurs utilisations pour prévenir et/ou traiter des affections et/ou des maladies dans lesquelles les récepteurs Trk de neurotrophine et/ou les NCAM jouent un rôle important, et dont le traitement est favorisé par la stimulation de la croissance des neurites, de la survie cellulaire et de la plasticité neuronale associée à la mémoire et à l'apprentissage, et/ou par la modulation de la motilité cellulaire.
