  • Patent number: 11642369
    Abstract: To enhance expression of an antioxidant-related substance in an epidermis by using a diacylglycerol PEG adduct, a method for enhancing expression of an antioxidant-related substance in an epidermis is provided which includes applying a diacylglycerol PEG adduct to the epidermis as an active ingredient. The antioxidant-related substance is an oxidative stress response gene, an antioxidant enzyme, or an antioxidant protein.

  • Patent number: 8349359
    Abstract: The invention is a composition administrable orally to provide systemic glutathione (reduced) and a method for providing systemic glutathione by oral administration of glutathione (reduced) in a liposome encapsulation. The administration of a therapeutically effective amount of oral liposomal glutathione (reduced) results in improvement of symptoms in disease states related to glutathione deficiency such as Parkinson's disease and cystic fibrosis. Compounds enhancing the effect of the liposomal glutathione are contemplated such as Selenium, EDTA, carbidopa, and levodopa.

  • Publication number: 20120232169
    Abstract: (PEG)-lipid conjugates and methods of preparation are disclosed herein. Methods of preparation may involve stepwise addition of small PEG oligomers to a glycerol backbone until a desired chain size is attained. Polymers resulting from the syntheses may be highly monodisperse. The resulting polymers may comprise branched polyethyleneglycol (PEG)-lipid conjugates. The present disclosure may provide several advantages such as simplified synthesis, high product yield and low cost for starting materials. The present synthesis method may be suitable for preparing a wide range of conjugates such as PEG lipid conjugates having a glycerol-like central backbone covalently attached to two or more monodisperse PEG chains and a lipid comprising a range of diesters made from fatty acids or bile acids.

  • Publication number: 20110105387
    Abstract: The invention comprises a method of treatment using an oral capsule dose of rapamycin formulated with PEG-lipids. Two types of PEG-lipids are used in the formulation. A solubilizing agent dissolves the rapamycin, and solidifying agent is used to convert the solution of rapamycin/solubilizing agent to a more solid form.

  • Publication number: 20100330033
    Abstract: The invention provides compositions and methods for covalent attachment of polymer and lipid carriers to therapeutic proteins to form carrier-protein conjugates having linkers between the carrier and protein portions of the conjugates. The linkers are selected to minimize steric effects. The linkers reduce the shielding effect of the carrier on the therapeutic protein and also allow better access for enzymatic or chemical cleavage of the carbamate bond. The linkers attach to the therapeutic protein via a carbamate bond and are either directly adjacent to the carbamate bond or are separated by a single carbon having a nitrogen side chain. Such linkers are solely comprised of carbon, sulfur and hydrogen and are between four and ten atoms (either C or S) in length.
