  • Patent number: 8637535
    Abstract: Solid phases of (?)-cis-FTC, which are designated herein as amorphous (?)-FTC and Forms II and III (?)-cis-FTC) are provided that can be distinguished from Form I (?)-cis-FTC by X-ray powder diffraction patterns, thermal properties, and methods of manufacture. A hydrated crystalline form of (±)-cis-FTC (i.e. racemic cis-FTC), and a dehydrated form of the hydrate, are also provided, and can similarly be distinguished from other forms of FTC by X-ray powder diffraction patterns, thermal properties, and methods of manufacture. These FTC forms can be used in the manufacture of other forms of FTC, or in pharmaceutical compositions. Particularly preferred uses of these forms are in the treatment of HIV or hepatitis B.

  • Patent number: 8445670
    Abstract: A method of synthesizing stereochemically defined iminocyclitol comprises replacing an intraring oxygen in a cyclic sugar by an intraring imine to form an iminocyclitol, wherein said iminocyclitol has a defined stereochemical configuration different from a stereochemical configuration of the cyclic sugar. The invention also provides combinatorial libraries of iminocyclitol compounds, allowing for diverse C1 and N-substitution. In addition, provided are methods of treating viral infections with iminocyclitols compounds.

  • Patent number: 8349892
    Abstract: Moderate moisture levels, such as greater than 3% but no greater than 7%, may be beneficial for solid formulations of certain prostacyclin analogs. Accordingly, a solid formulation containing a prostacyclin analog may be packaged inside a pharmaceutical packaging with such amount of a desiccant or a drying agent that after the storage the solid formulation may have a moderate level of moisture in it.

  • Patent number: 6706728
    Abstract: A system for treating a condition associated with a mucosal surface, the system comprising an immune response modifier (IRM) compound chosen from imidazoquinoline amines, imidazopyridine amines, 6,7-fused cycloalkylimidazopyridine amines, imidazonaphthyridine amines, oxazoloquinoline amines, thiazoloquinoline amines, 1,2-bridged imidazoquinoline amines, and pharmaceutically acceptable salts thereof and an applicator device for applying the IRM compound to the mucosal surface. This system of IRM compounds and applicator may be used to treat conditions associated with mucosal surfaces such as cervical dysphasia and cervical intraepithelial neoplasia.
