A novel compound, purpurone (1), with ATP-citrate lyase inhibitory activity, was isolated from the marine sponge Iotrochota sp. Its structure was established mainly on the basis of NMR spectroscopic data. Purpurone represents the first example of a new class of marine products.

Alterations of certain metabolite concentrations and fluxes that occur in response to viral infection are described. Host cell enzymes in the involved metabolic pathways are selected as targets for intervention; i.e., to restore metabolic flux to disadvantage viral replication, or to further derange metabolic flux resulting in “suicide” of viral-infected cells (but not uninfected cells) in order to limit viral propagation. While any of the enzymes in the relevant metabolic pathway can be selected, pivotal enzymes at key control points in these metabolic pathways are preferred as candidate antiviral drug targets. Inhibitors of these enzymes are used to reverse, or redirect, the effects of the viral infection. Drug candidates are tested for antiviral activity using screening assays in vitro and host cells, as well as in animal models. Animal models are then used to test efficacy of candidate compounds in preventing and treating viral infections. The antiviral activity of enzyme inhibitors is demonstrated.
