Abstract

The present invention relates to phosphonate compounds, compositions containing them, processes for obtaining them, and their use for treating a variety of medical disorders, e.g., osteoporosis and other disorders of bone metabolism, cancer, viral infections, and the like.

Claims

1. A compound consisting a phosphonate monoester formed by a covalent linking of tenofovir to a (C₁-C₂₄)alkylpropanediol or (C₁-C₂₄)alkoxypropan-1-ol, or a pharmaceutically acceptable salt thereof.

2. The compound of claim 1, wherein tenofovir is covalently linked to hexadecyloxypropan-1-ol.

3. The compound of claim 1, wherein the compound has the structure:

4. A composition comprising a compound of claim 1 and a pharmaceutically acceptable carrier.

5. A method for the treatment of a viral disease selected from human immunodeficiency virus, influenza, herpes simplex virus, human herpes virus, cytomegalovirus, hepatitis B and C virus, Epstein-Barr virus, varicella zoster virus, orthopox virus, ebola virus and papilloma virus comprising administering an effective amount of a compound optionally in a pharmaceutically acceptable carrier, wherein the compound comprises a phosphonate ester formed by a covalent linking of tenofovir to an alkylpropanediol or alkoxyalkanol, or a pharmaceutically acceptable salt thereof.
