BENZOTHIOPHENE DERIVATIVES

摘要

The present invention relates to a novel class of benzothiophene amide derivatives. The hydroxamic acid compounds can be used to treat cancer. The benzothiophene amide 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 inhibiti ng proliferation of such cells. Thus, the compounds of the present invention ar e useful in treating a patient having a tumor characterized by proliferation o f 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 o f diseases of the central nervous system (CNS), such as neurodegenerative diseases. The present invention further provides pharmaceutical compositions comprising the hydroxamic acid derivatives and safe dosing regimens of these pharmaceutical compositions, which are easy to follow, and which result in a therapeutically effective amount of the hydroxamic acid derivatives in vivo.
