Patent

CA 2679831

The invention provides methods for treating stroke and compositions for use in the same. The methods employ a chimeric peptide pf an active peptide and an internalization peptide. The internalization peptide is a tat variant that promotes uptake of itself and a linked active peptide into a cell without substantial binding to N-type calcium channels. Use of the tat variant allows treating of stroke free of certain side effects associated with binding to N-type calcium channels. Tat variant peptides can also be linked to other active agent for use in treating other diseases.

La présente invention concerne des procédés permettant de traiter les incidents cérébrovasculaires, et des compositions destinées à être utilisées dans lesdits procédés. Ces procédés emploient un peptide chimérique d'un peptide actif et un peptide d'internalisation. Ledit peptide d'internalisation est une variante Tat qui favorise l'absorption de lui-même et d'un peptide actif lié dans une cellule sans liaison substantielle à des canaux de calcium de type N. L'utilisation de la variante Tat permet le traitement d'incidents cérébrovasculaires sans certains effets secondaires associés aux canaux de calcium de type N. Les peptides de variante Tat peuvent également être liés à d'autres agents actifs pour être utilisés dans le traitement d'autres maladies.
