Abstract: This invention discloses a method for preparing a therapeutic or diagnostic complex comprised of a nucleic acid ligand and a lipophilic compound or non-immunogenic, high molecular weight compound by identifying a nucleic acid ligand by SELEX methodology and associating the nucleic acid ligand with a lipophilic compound or a non-immunogenic, high molecular weight compound. The invention further discloses complexes comprising one or more nucleic acid ligands in association with a lipophilic compound or non-immunogenic, high molecular weight compound.

Abstract: The present invention provides a novel method for simultaneously inhibiting the cyclooxygenase COX-2 and 5-lipoxygenase (5-LO) enzymes. The method for the simultaneous dual inhibition of COX-2 and 5-LO is comprised of administering a composition containing an individual and/or a mixture of multiple flavans isolated from a single plant or multiple plants in the Acacia genus of plants to a host in need thereof. The present also includes novel methods for the prevention and treatment of COX-2 and 5-LO mediated diseases and conditions. The method for preventing and treating COX-2 and 5-LO mediated diseases and conditions is comprised of administering to a host in need thereof an effective amount of a composition comprising an individual and/or a mixture of multiple flavans isolated from a single plant or multiple plants in the Acacia genus of plants and a pharmaceutically acceptable carrier.

Abstract: Lipid-containing prodrugs are provided for treating viral infections due to herpes, influenza, hepatitis B, Epstein-Barr, and varicella zoster viruses, as well as cytomegalovirus and derivatives of antiviral agents. The compounds comprise phosphonoacids having antiviral activity which are linked, either through the phosphate group or carboxyl group of the phosphonoacid, to one of a selected group of lipids. Phosphonoacetic acid and phosphonoformic acid are thus linked to phospholipids, glycerolipids, sphingolipids, glycolipids, or fatty acids. The compounds persist, after intracellular hydrolysis, as the antiviral phosphonoacids. The lipid prodrugs are effective in improving the efficacy of antiviral phosphonoacids by prolonging their antiviral activity following administration.
