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.

Polymer-carbohydrate conjugates for drug delivery technology

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, nutraceuticals, 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.

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.

Polymer-carbohydrate-lipid conjugates

The invention comprises various aqueous PEG-carbohydrate-lipid based formulations of pharmaceutical active ingredients including compositions for intravenous injections. This invention relates to methods and compositions for improving solubility and the safety profile of pharmaceutical compounds. More particularly, the present invention relates to employing PEG-carbohydrate-lipid conjugates for formulating drug compositions having increased solubility or dispersivity and enhanced stability.

Pharmaceutical compositions for parenteral administration

New diacylglycerol-polyethylene glycol (DAG-PEG) conjugates are described. A variety of linkers between the PEG chain and glycerol backbone of the DAG-PEGs may be selected to optimize liposomal formulations of pharmaceuticals and cosmetics.
