20080286351Pegylated Cardiolipin Analogs, Methods of Synthesis, and Uses Thereof - The invention provides synthetic methods for PEGylated cardiolipins with varying linkers. The methods can be employed to prepare PEGylated cardiolipin with different fatty acid and/or alkyl chain length with or without unsaturation. The PEGylated cardiolipin, prepared by the present methods, can be incorporated into liposomes that can also include active agents such as hydrophilic or hydrophobic drugs for the treatment of human and animal diseases. In addition, the PEGylated cardiolipin can be incorporated into liposomes that include compounds for therapeutic and diagnostic imaging. The use of such liposomes with PEGylated cardiolipin prolongs the period of liposomal circulation without disrupting the lipid bilayer.11-20-2008
20080300418Synthesis of Cardiolipin Analogues and Uses Thereof - The invention provides novel synthetic methodologies for preparing cardiolipin, migrated caridiolipin (1,2-positional isomer of cardiolipin) and their analogues having varying fatty acids and/or alkyl chains with varying length and degrees of saturation/unsaturation. The method comprises (a) reacting an optically pure 1,2-O-dialkyl-sn-glycerol or 1,2-O-dialkyl-sn-glycerol with one or more phosphoramidite reagent(s), wherein a phosphite triester is produced; (b) coupling the product of (a) with glycerol, wherein a protected cardiolipin is produced; and (c) deprotecting the protected cardiolipin, such that cardiolipin is prepared. The cardiolipins and analogues thereof, prepared by the present methods, can be incorporated into liposomes, which can also include active agents such as hydrophobic or hydrophilic drugs, antisense nucleotides or diagnostic agents. Such liposomes can be used to treat diseases or can be used in diagnostic and/or analytical assays.12-04-2008
20090011001Manufacturing process for liposomal preparations - The present invention provides a manufacturing process for liposomal preparations comprising water-insoluble or hydrophobic active principals. In accordance with one aspect of the inventive method, at least one active principal and lipid fraction are dissolved in an organic solvent. This solution is then subjected to reduced pressure (vacuum) in a container with or with out inert packing to remove the organic solvent, thereby forming a puffy cake comprising the active principal or principals and lipid fraction. This puffy cake is then mixed with an aqueous solution, under controlled conditions suitable to form a bulk liposomal preparation. Because the active principal is imbedded in the lipid bilayer, removal of the aqueous solution is optional.01-08-2009
20100041142ANTI-APOPTOTIC GENE SCC-S2 AND DIAGNOSTIC AND THERAPEUTIC USES THEREOF - A gene that is a positive mediator of tumor growth and metastasis in certain cancer types is provided. This gene and corresponding polypeptide have diagnostic and therapeutic application for detecting and treating cancers that involve expression of SCC-S2 such as renal, ovarian, head and neck, breast, prostate, brain, chronic myelogenous leukemia, lung, lymphoblastic leukemia, and colorectal adenocarcinoma cells.02-18-2010
20100068251Aqueous Systems For The Preparation Of Lipid Based Pharmaceutical Compounds; Compositions, Methods, And Uses Thereof - The present invention relates to a methods of preparing active compounds complexed with lipids using aqueous systems that are free of organic solvents, and methods of using the complexes, e.g., in treating a disease in a subject. In some embodiments, the present invention comprises a composition comprising a complex comprising at least one active compound, e.g., a polyene antibiotic, an immunosuppressant agent such as tacrolimus or a taxane or taxane derivative, and one or more lipids. In some embodiments, the present invention provides a method comprising preparing a composition comprising a lipid complex comprising at least one active compound and at least one lipid and administering the composition to a subject. In certain embodiments the subject is a mammal. In certain preferred embodiments, the subject is human.03-18-2010
20100323000METHOD AND PROCESS FOR PREPARING CARDIOLIPIN - The invention provides novel methods for preparing cardiolipin and cardiolipin analogs having varying fatty acid chain lengths, particularly 1,1′,2,2′-tetramyristoyl cardiolipin. The methods comprise reacting a starting compound, such as a 1,2-O-sn-diacylglycerol and a 2-protected glycerol, with a phosphoramidite reagent to produce a protected cardiolipin, which is deprotected to prepare cardiolipin. The cardiolipin and cardiolipin analogs may be prepared in the presence of an activator, such as pyridinium trifluororacetate. The methods of the present invention are used to prepare cardiolipin and cardiolipin analogs in large quantities. The cardiolipin prepared by the present methods can be incorporated into liposomes which can also include active agents such as hydrophobic or hydrophilic drugs. Such liposomes can be used to treat diseases or in diagnostic and/or analytical assays.12-23-2010
20110104252ANTI-APOPTOTIC GENE SCC-S2 AND DIAGNOSTIC AND THERAPEUTIC USES THEREOF - A gene that is a positive mediator of tumor growth and metastasis in certain cancer types is provided. This gene and corresponding polypeptide have diagnostic and therapeutic application for detecting and treating cancers that involve expression of SCC-S2 such as renal, ovarian, head and neck, breast, prostate, brain, chronic myelogenous leukemia, lung, lymphoblastic leukemia, and colorectal adenocarcinoma cells.05-05-2011
20110212167LIPID BASED PHARMACEUTICAL PREPARATIONS FOR ORAL AND TOPICAL APPLICATION; THEIR COMPOSITIONS, METHODS, AND USES THEREOF - The present invention relates to the topical and oral delivery of a composition comprising one or more active agents for treating a disease or symptoms in a subject. In some embodiments, the present invention comprises a composition comprising at least one active compound, e.g., finasteride or minoxidil, and one or more lipids. In some embodiments, the present invention relates to composition and method of preparation for treating androgenic alopecia (AGA), prevention of hair loss and female hirsutism. In some embodiment, the present invention comprises finasteride and at least one lipid component for the treatment of benign prostatic hyperplasia. In some embodiment, the present invention comprises tacrolimus or amphotericin B and at least one lipid component for the treatment of skin or eye related diseases. The present invention provides a method of preparation of a composition comprising at least one active compound and at least one lipid and administering the composition to a subject by oral or topical delivery. In certain embodiments the subject is a mammal. In certain preferred embodiment, the subject is human.09-01-2011
