  • SALTS OF (3-0-(3',3'-DIMETHYLSUCCINYL) BETULINIC ACID AND SOLID STATE FORMS THEREOF
    Publication number: 20110224182
    Abstract: The present invention concerns novel pharmaceutically active compounds, pharmaceutical compositions containing the same, methods of making the compounds, polymorphic forms of the compounds, the compounds for use as medicaments, and use of the compounds for the manufacture of medicaments. The present invention also concerns a method of treatment involving administration of the compounds. Specifically, the compounds are certain salts of 3-O-(3?,3?-dimethylsuccinyl)betulinic acid, also known as “DSB.” The novel compounds are useful as antiretroviral agents. In particular, the novel compounds are useful for the treatment of Human Immunodeficiency Virus (“HIV”).
