摘要:
The present invention provides three-dimensional structural information from the hyperthermophilic bacterium Aquifex aeolicus which is a histone deacetylase-like protein (HDLP). HDLP shares 35.2% amino acid sequence identity with human histone deacetylase (HDAC1). The present invention further provides three-dimensional structural information of HDLP bound by inhibitor molecules. The three-dimensional structural information of the present invention is useful to design, isolate and screen deacetylase inhibitor compounds capable of inhibiting HDLP, HDAC family members and HDLP-related molecules. The invention also relates to nucleic acids encoding a mutant HDLP which facilitates the determination of the three-dimensional structure of HDLP in the presence of a zinc atom.

The invention provides compounds, several of which belong to a class having two or more nonpolar components connected by a polar group and having polar groups on the termini of the compound. The invention also concents a method of selectively inducing termini differentiation of neoplastic cells and thereby inhibiting proliferation of such cells which comprises contacting the cells under suitable condition with an amount of the compound effective to selectively induce terminal differentiation. Moreover, the invention provides a method of treating a patient having a tumor characterized by proliferation of neoplastic cells which comprises administering to the patient an amount of the compound effective to selectively induce terminal differentiation of such neoplastic cells, thereby inhibiting their proliferation and suppressing oncogenicity. Lastly, the present invention provides a pharmaceutical composition comprising a pharmaceutically acceptable carrier and the compound in an amount effective less than an amount which would cause toxicity in the patient.

Sont décrits des composés dont certains appartiennent à une classe présentant deux composants non polaires ou plus, connectés par un groupe polaire et dotés de groupes polaires aux terminaisons du composé. L'invention concerne également un procédé d'induction sélective d'une différenciation de terminaisons de cellules néoplastiques, et par conséquent d'inhibition de la prolifération desdites cellules, consistant à mettre en contact les cellules dans des conditions adaptées, avec une quantité du composé suffisante pour induire sélectivement une différenciation de terminaisons. De plus, l'invention concerne un procédé de traitement d'un patient présentant une tumeur caractérisée par la prolifération de cellules néoplastiques, consistant à administrer au patient une dose du composant suffisante pour induire sélectivement la différenciation des terminaisons desdites cellules néoplastiques, inhibant ainsi leur prolifération et supprimant l'oncogénicité. En outre, l'invention concerne une préparation pharmaceutique comprenant un excipient acceptable en pharmacologie, ainsi que le composé en une dose efficace, inférieure à une dose susceptible de provoquer une toxicité chez le patient.

摘要:
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.

The present application is directed to a method of inhibiting HDAC in the brain of a mammal. The method comprises administering to a mammal a HDAC inhibiting amount of a histone deacetylase inhibitor compound. The present application is further directed to a method of treating diseases of the central nervous system (CNS) comprising administering to a individual in need of treatment a therapeutically effective amount of an inhibitor of HDAC. In particular embodiments, the CNS disease is a neurodegenerative disease. In further embodiments, the neurogenerative disease is an inherited neurodegenerative disease, such as those inherited neurodegenerative diseases which are polyglutamine expansion diseases. In other embodiments, the disorder is cancer of the brain. The individual is a mammal, such as a primate or human.
