  • Patent number: 6852870
    Abstract: The present invention is directed to a method of treating patients with major depression by administering omega-3 fatty acids. These may be administered in a substantially purified form, as part of a pharmaceutical composition, or as part of a larger molecule, e.g., a triacylglycerol, which releases free fatty acid after ingestion by a patient. The present invention is also directed to triacylglycerols which are esterified at the gamma cardon of glycerol to phosphocholine and at either the alpha or beta carbon of glycerol to an omega-3 fatty acid. These “omega-3 phoshatidylcholines” are also used in the treatment of patients with major depression.

  • Patent number: 6794524
    Abstract: The invention relates to a series of novel ester containing phosphobetaine compounds, which are exceptional surface active agents that provide outstanding foam and are very mild to the hair and skin, in addition because of the presence of the ester linkage these materials are not persistent in the aquatic environment. This lack of persistence in the aquatic environment makes these materials greener and environmentally friendly than other non-ester containing compounds. The compounds, because they contain a pendant ionizable phosphate group and a quaternary amine compound are amphoteric surfactants that is they contain both a positive and negative charge in the same molecule. This combination of properties makes these polymers ideally suited for use in personal care applications.

    Abstract: Disclosed is a method for reducing the sterol, for example cholesterol, content of sterol-containing substances such as fats and oils. The method provides an efficient and cost effective process based on the affinity of cholesterol and other sterols for amphipathic molecules that form hydrophobic, fluid bilayers, such as phospholipid bilayers. Aggregates of amphipathic molecules are contacted with, for example, a sterol-containing fat or oil in an aqueous environment and then mixed. Following adequate mixing, the sterol-reduced fat or oil is separated from the aqueous separation mixture. Alternatively, the correspondingly sterol-enriched fraction also may be isolated from the aqueous separation mixture.

  • Patent number: 6224903
    Abstract: A fusogenic liposome composition for delivering a liposome-entrapped compound into the cytoplasm of a target cell is described. The liposomes have an outer surface coating of chemically releasable hydrophilic polymer chains which shield hydrophobic polymers on the liposome outer surface. Release of the hydrophilic polymer chains exposes the hydrophobic polymers for interaction with outer cell membranes of the target cells to promote fusion of the liposome with the target cells. Also disclosed is a polymer-lipid conjugate for use in promoting fusion between target membranes. The conjugate is composed of a first segment composed of a hydrophilic polymer and a second hydrophobic polymer segment. The second segment is joined to the first segment by a bond effective to release the first segment in response to an existing or an induced physiologic condition. Attached to the second segment is a vesicle-forming lipid member.

  • Patent number: 6183979
    Abstract: A method for preparation of an air-dried prothrombin time (PT) reagent which uses a recombinant protein and synthetic phospholipids is described. The source for the recombinant protein is rabbit brain, and the phospholipids employed are palmitoyloleoylphosphatidylcholine (POPC) and palmitoyloleoylphosphatidylserine (POPS). The particular formulation buffer used to dilute the lipidated tissue factor provides a reagent that is dried without lyophilization and remains stable for at least 2 weeks at 37 C. A method for preparing the improved PT reagent and a method of using the reagent to analyze blood PT is also provided.

  • Patent number: 6171614
    Abstract: The present invention provides glycophospholipid and peptide-phospholipid conjugates comprising a phospholipid moiety and a saccharide or peptide moiety joined by an ether linkage comprising a secondary or tertiary amine. The conjugate structure of the invention comprises a flexible spacer arm between the phospholipid and saccharide or peptide moieties which, being variable in length, serves to optimize saccharide or peptide bioactivity. This invention further provides a method for the synthesis of such conjugates comprising the step of reductive amination. The method is efficient, economical and provides a high yield of product. Glycophospholipid and peptide-phospholipid conjugates of the invention can be incorporated and, optionally, chemically polymerized in self-assembling systems such as membranes, bilayers, films, liposomes and the like, and find utility diagnostically and therapeutically in medical and immuno-biological applications.
