  • Publication number: 20200318990
    Abstract: A method of producing a transit-time map uses a digital mapping service, a digital transit-time mapping program, and a connected digital device. A user-defined initial location, a pre-defined transit-time, and a user-chosen travel mode are input into the digital transit-time mapping program, Running the digital transit-time mapping program includes repeatedly accessing the digital mapping service to determine a locus of points on the digital spatial map. The time to travel from the user-defined initial location to each point of the locus of points is substantially equal to the pre-defined transit time for the user-chosen travel mode. The points of the locus of points on the digital spatial map are stored.

  • Publication number: 20040047903
    Abstract: A liposome having a lipid bilayer, where the lipid bilayer includes either the L or D stereoisomer of an ether lipid or a non-equal mixture of both. Most preferably the liposome also comprises (a) an underivatized phosphatidylcholine; (b) a sterol; (c) about 5-20 mole % of a phosphatidylethanolamine linked to a dicarboxylic acid at the ethanolamine group of the phosphatidylethanolamine, and (d) greater than about 10 mole % to less than about 30 mole % of either the L or D stereoisomer of an ether lipid. The liposome may be used as an anti-cancer or anti-inflammatory agent.

  • Patent number: 6500461
    Abstract: This invention provides vehicles capable of delivering high concentrations of poorly hydrophilic/poorly lipophilic compounds to animals, by combining compounds having biocompatible hydrophobic domains with conjugates having both hydrophobic and hydrophilic regions. Such formulations are suitable for a number of uses in animals, particularly the administration thereto of high concentrations of therapeutically useful compound, without an undue level of side effects.

  • Patent number: 6482850
    Abstract: Provided herein is a taxane having a hydrocarbon attached at the 2′ and/or 7 positions, the hydrocarbon's alpha position being occupied by a “hydrolysis-promoting group” (“HPG”). In one embodiment, the hydrolysis promoting group is stereospecifically attached to the &agr;-carbon of the hydrophobic taxane. The Substitution of an HPG for the methylene unit ordinarily occupying the alpha position allows for enhanced in vivo hydrolysis of the hydrocarbon-taxane bond, and hence, for enhanced taxane therapeutic activity. Also provided herein are taxane-containing compositions, and methods of administering taxanes to animals, including those afflicted with cancers or inflammatory diseases.

In one embodiment, the hydrolysis promoting group is stereospecifically attached to the a-carbon of the hydrophobic taxane. The Substitution of an HPG for the methylene unit ordinarily occupying the alpha position allows for enhanced in vivo hydrolysis of the hydrocarbon-taxane bond, and hence, for enhanced taxane therapeutic activity. Also provided herein are taxane-containing compositions, and methods of administering taxanes to animals, including those afflicted with cancers or inflammatory diseases.

  • Patent number: 6291690
    Abstract: This invention provides a taxane derivative of the formula: wherein a hydrophobic organic moiety is attached to a taxane. R and R1 is each indepently H or a hydrophobic organic moiety, as long as at least one of R and R1 is not H. Attachment of a hydrophobic organic moiety to the taxane so as to obtain a taxane derivative generally stabilizes the association of the derivative with a lipid, including a liposomal lipid, carrier in the plasma of animals to which the derivative-carrier association is administered. Also provided herein is a composition containing the taxane derivative and a pharmaceutically acceptable medium; desirably, the medium also contains a lipid carrier, and the derivative is associated with the carrier. Further provided herein is a method of administering taxane derivatives to animals, for example, animals afflicted with cancers.
