Abstract: The present invention relates to phosphonate, nucleoside phosphonate or nucleoside phosphate compounds, compositions containing them, processes for obtaining them, and their use in treating a variety of medical disorders, in particular viral infections, cancers and the like.

Abstract: The present application provides methods and compositions for improving the bioavailability of a lipid-containing antiviral compound, and in particular, an antiviral lipid-containing compound. In one embodiment, pharmaceutically acceptable compositions are provided that include an antiviral lipid-containing compound, or salt, ester, or prodrug thereof and one or more bioavailability enhancing compounds, such as inhibitors of cytochrome P450 enzymes.

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: This application provides a process for preparing enantiomerically pure ?-D-dioxolane nucleosides. In particular, a new synthesis of (?)-DAPD, suitable for large scale development, is described. In one embodiment the invention provides a process for preparing a substantially pure ?-D- or ?-L-1,3-dioxolane nucleosides comprising a) preparing or obtaining an esterified 2,2-dialkoxy ethanol; b) cyclizing the esterified 2,2-dialkoxy ethanol with glycolic acid to obtain a 1,3-dioxolane lactone; c) resolving the 1,3-dioxolane lactone to obtain a substantially pure D- or L-lactone; d) selectively reducing and activating the D- or L-chiral lactone to obtain a substantially pure D- or L-1,3-dioxolane; e) coupling the D- or L-1,3-dioxolane to an activated and/or protected purine or pyrimidine base; and f) optionally purifying the nucleoside to obtain a substantially pure protected ?-D- or P-L-1,3-dioxolane nucleoside.
