CA 2476434

The present invention provides a novel method for treating and/or preventing thioredoxin (TRX)-mediated diseases and conditions, by administering to a subject in need of such treatment a therapeutically effective amount of a histone deacetylase (HDAC) inhibitor or a pharmaceutically acceptable salt or hydrate thereof. The HDAC inhibitor can alter the expression of a thioredoxin- binding-protein (e.g. TBP-2), which in turn can lead to an altered TRX/thioredoxin-binding-protein cellular binding interaction, resulting in an increase or decrease in the level or activity of cellular TRX, for example the expression level or reducing activity of TRX. Thus the present invention relates to the use of HDAC inhibitors in a method of preventing and/or treating a wide variety of thioredoxin (TRX)-mediated diseases and conditions, such as inflammatory diseases, allergic diseases, autoimmune diseases, diseases associated with oxidative stress or diseases characterized by cellular hyperproliferation.

L'invention concerne une nouvelle méthode de traitement et/ou de prévention des maladies et d'états pathologiques médiés par la thiorédoxine (TRX), ladite méthode consistant à administrer à un sujet, nécessitant ledit traitement, une quantité thérapeutiquement efficace d'un inhibiteur de l'histone-déacétylase (HDAC) ou un des sels pharmaceutiquement acceptable ou un de ses hydrates. Ledit inhibiteur de HDAC peut transformer l'expression d'une protéine de liaison de la thiorédoxine (par exemple TBP-2), qui à son tour peut conduire à une interaction transformée de la liaison cellulaire de TRX/protéine de liaison de la thiorédoxine, en faisant augmenter ou diminuer le niveau ou l'activité de la TRX cellulaire, par exemple le niveau d'expression ou l'activité de réduction de la TRX. L'invention concerne également l'utilisation des inhibiteurs de HDAC dans une méthode de prévention et/ou de traitement d'une pluralité de maladies et d'états pathologiques médiés par la thiorédoxine (TRX), tels que des maladies inflammatoires, des maladies allergiques, des maladies auto-immunes, des maladies associées à un stress oxydatif ou des maladies caractérisées par une hyperprolifération cellulaire.
