Methods and pharmaceutical compositions comprising a low dose of a farnesyl transferase inhibitor useful in the treatment of proteinopathies are provided. These low doses are below the doses used in oncological treatments for which these compounds were initially designed. The treatment includes administering to a subject in need thereof a therapeutically effective amount of a farnesyl transferase inhibitor, wherein the amount is effective to inhibit the farnesylation of a non-Ras FTase substrate involved in the autophagy pathway without substantially affecting the farnesylation of Ras or other oncology related substrates. Treatments in accordance with the present invention may also include an acetylcholinesterase inhibitor, an activator of neurotrophic receptors, an NMDA anatagonist, an amyloid deposit inhibitor, an antipsychotic agent, an antidepressant, an anxiolytic, or an antioxidant.

La présente invention concerne des procédés et des compositions pharmaceutiques comprenant une faible dose d'un inhibiteur de farnésyle transférase utiles dans le traitement de protéinopathies. Ces faibles doses sont au-dessous des doses utilisées dans des traitements oncologiques pour lesquels ces composés ont été initialement conçus. Le traitement comprend l'administration à un sujet nécessitant celui-ci d'une quantité thérapeutiquement efficace d'un inhibiteur de farnésyle transférase, où la quantité est efficace pour inhiber la farnésylation d'un substrat de FTase non-Ras impliqué dans la voie d'autophagie sans affecter sensiblement la farnésylation de Ras ou d'autres substrats de type oncologique. Des traitements selon la présente invention peuvent comprendre en outre un inhibiteur d'acétylcholinestérase, un activateur de récepteurs neurotrophiques, un antagoniste de NMDA, un inhibiteur de dépôt amyloïde, un agent antipsychotique, un antidépresseur, un anxiolytique, ou un antioxydant.
