Abstract:
New triazole antifungal agents having C6S7 or S6C7 bridges are disclosed. These triazoles provide alternatives to existing antifungals in terms of formulation, bioavailability and activity.
Abstract:
The invention comprises compounds, methods of making, and methods of using. A group of polymer-cyclodextrin-lipid conjugates having a center backbone and three or four appended functional groups are disclosed, wherein one of the hydrophilic components is cyclodextrin. The compounds may have a backbone with three or four appended functional groups: one or two lipophilic compounds including sterols or “fat soluble” vitamins or fatty acids, one or two hydrophilic polymer and one cyclodextrin. Specific functional groups may be selected for specific applications in formulating pharmaceuticals, cosmetics, nutriceuticals, and the like. Typical coupling reaction of the conjugates may involve one or more or combinations or in series of alkylation including N-alkylation or O-alkylation, etherification, esterification and amidation chemical processes. A variety of linkers between the center backbone and functional groups may also be selected to modify the carriers or center backbones for the coupling reactions and optimize performance of the conjugates.
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.
Abstract:
The invention comprises compounds, methods of making, and methods of using. The compounds may have a backbone and three appended functional groups: one lipid, one hydrophilic polymer, and one carbohydrate. Specific functional groups may be selected for specific applications in formulating pharmaceuticals, cosmetics, nutriceuticals, and the like. A variety of linkers between the backbone and functional groups may also be selected to optimize performance.

Abstract:
New prodrugs are derived from highly water soluble parent drugs that exist as primary or secondary amines in their parent form. Lipophilic carrier groups are bonded to the parent drug via an amide linkage with additional linker elements between the amide group and the carrier group.

Abstract:
The invention comprises compounds, methods of making, and methods of using. The compounds may have a linear or cylic backbone and three or four appended functional groups: one or two lipohilic compounds including sterols or “fat soluble” vitamins, one or two hydrophilic polymer, and one or two carbohydrate. A group of polymer-carbohydrate conjugates having a central backbone and three appended functional groups are disclosed wherein one lipophilic compound is void of both steroid acids. The conjugate may have fatty acids as the primary lipophilic carrier, one hydrophilic polymer, and one carbohydrate. Specific functional groups may be selected for specific applications in formulating pharmaceuticals, cosmetics, nutriceuticals, and the like. Typical coupling reaction of the conjugates may involve one or more or combinations or in series of alkylation including N-alkylation or O-alkylation, etherification, esterification and amidation chemical processes. A variety of linkers between the backbone and functional groups may also be selected to modify the carriers or center backbones for the coupling reactions and optimize performance of the conjugates.
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.
Abstract:
Diacyl lipid-polymer conjugates are used to enhance the solubility of lipophilic drugs in aqueous solution. The conjugates comprise a backbone, two lipophilic acyl groups and a hydrophilic polymer.
