  • Patent number: 9096559
    Abstract: The present invention relates to a novel class of 4-carboxybenzylamino derivatives. The 4-carboxybenzylamino compounds can be used to treat cancer. The 4-carboxybenzylamino compounds can also inhibit histone deacetylase and are suitable for use in selectively inducing terminal differentiation, and arresting cell growth and/or apoptosis of neoplastic cells, thereby inhibiting proliferation of such cells. Thus, the compounds of the present invention are useful in treating a patient having a tumor characterized by proliferation of neoplastic cells. The compounds of the invention may also be useful in the prevention and treatment of TRX-mediated diseases, such as autoimmune, allergic and inflammatory diseases, and in the prevention and/or treatment of diseases of the central nervous system (CNS), such as neurodegenerative diseases.

  • Patent number: 8227636
    Abstract: The present invention is directed to prodrugs of hydroxamic acid based histone deacetylase (HDAC) inhibitors, e.g., suberoylanilide hydroxamic acid (SAHA). The prodrugs are acylated derivatives having increased aqueous solubility and cellular permeability as compared with the free hydroxamic acid, and are useful for inhibiting HDACs, and for selectively inducing terminal differentiation, cell growth arrest and/or apoptosis of neoplastic cells, thereby inhibiting proliferation of such cells. Thus, the prodrugs of the present invention are useful in treating a patient having a tumor characterized by proliferation of neoplastic cells. The prodrugs of the invention are also useful in the prevention and treatment of thioredoxin (TRX)-mediated diseases, such as autoimmune, allergic and inflammatory diseases, and in the prevention and/or treatment of diseases of the central nervous system (CNS), such as neurodegenerative diseases.
