A pharmaceutical composition for anti-viral cancer treatment in mammals, comprising a therapeutically effective amount of Anisomelic acid or salts thereof. The pharmaceutical composition may comprise Anisomelic acid or salt thereof in an oil-in-water emulsion, for example in an isotropic mixture of at least one oil and at least one surfactant or, alternatively, in a hydrophilic solvent and a co-solvents or surfactant or a combination thereof. A method of treating or preventing of cancer in a mammal, wherein the p53 pathway is deregulated by viral oncoproteins, is also provided.

Isosorbide-derived epoxies and methods of making same are disclosed. Isosorbide and its isomers are attached to glycidyl ether to make crosslinkable epoxy resin monomers. Adding the hydrophobic functional group into the backbone of isosorbide epoxy or adjusting the amount and type of crosslinker is operable to modify the mechanical properties and water uptake ratio (from <1 wt % to >50 wt %) of the isosorbide-derived epoxies for different uses. High water uptake epoxies with controllable biodegradation rate are suitable for drug delivery systems or extracellular matrices for biomedical applications, while low water uptake epoxies with strong mechanical properties may be used for can coatings, bone cements and other industrial additives and adhesives.
