Abstract: The disclosure describes methods of synthesis of phosphonate ester derivatives. Preferred methods according to the disclosure allow for large-scale preparation of phosphonate ester compounds having high purity. In some embodiments, preferred methods according to the disclosure also allow for the preparation of phosphonate ester derivatives without the use of chromatographic purification methods and in better yield than previously used methods for preparing such compounds. Also disclosed are morphic forms of phosphonate ester derivatives.

Abstract: The present application provides methods and compositions for combination therapy with antiviral compounds for the treatment of poxvirus infections, such as orthopox virus infections. In one embodiment, a method of treatment of a poxvirus infection is provided that comprises administering to a host in need thereof cidofovir, cyclic cidofovir, or a salt, ester, or prodrug thereof in combination or alternation with at least a second anti-poxvirus agent. The second anti-poxvirus agent is, for example, a biologic, such as a pegylated interferon.

Abstract: The present invention provides methods of treating viral infection of the eye or posterior ocular condition including administering a pharmaceutical composition comprising a compound described in the present application. In some embodiments, the pharmaceutical composition is topically administered. In another embodiment, the pharmaceutical composition is orally administered or intraocularly administered.

Abstract: Compounds are disclosed for treating AIDS, herpes, and other viral infections by means of lipid derivatives of antiviral agents. The compounds consist of nucleoside analogues having antiviral activity which are linked, commonly through a phosphate group at the 5′ position of the pentose residue, to one of a selected group of lipids. The lipophilic nature of these compounds provide advantages over the use of the nucleoside analogue alone. It also makes it possible to incorporate them into the lamellar structure of liposomes, either alone or combined with similar molecules. In the form of liposomes, these antiviral agents are preferentially taken up by macrophages and monocytes, cells which have been found to harbor the target HIV virus. Additional site specificity may be incorporated into the liposomes with the addition of ligands, such as monoclonal antibodies or other peptides or proteins which bind to viral proteins.
