Abstract:
composição farmacêutica de carreadores llpídlcos nanoestruturados de antraciclinas e ácidos graxos poliinsaturados co-encapsulados, processo de obtenqao e uso. a presente invenção descreve composições farmacêuticas de carreadores lipídicos nanoestruturados contendo antraciclinas na forma de par iônico com um ácido graxo e co-encapsulação de um ácido graxo poliinsaturado dotado de atividade antitumoral. a invenção propõe também o processo de obtenção desses carreadores e composições farmacêuticas contendo os mesmos, bem como o uso dessas composições no tratamento quimioterépico antitumoral. a composição proposta visa não somente a diminuição da toxicidade sistêmica e dos efeitos adversos causados pelas antraciclinas, como também alcançar maior seletividade e aumento da citotoxicidade para as células tumorais, através do sinergismo promovido pela co-encapsulação de um acido graxo poliinsa atividade antitumoral, como o dha.
Abstract:
The preparation and use of a transducing polypeptide (TP)- lipid vesicle complex having a small proportion of positively charged (cationic) lipids in the make-up of the lipid vesicle, e.g., liposome, for safe and efficient intracellular delivery of therapeutic agents, such as proteins, DNA, small molecules and/or other drugs, into a cell of a higher organism, in vitro or in vivo is disclosed. The delivery system of the invention results in increased efficacy of intracellular delivery of such agents, bypassing the endocytotic pathway of intracellular delivery while at the same time minimizing the toxicity of the delivery system towards the recipient cells.

Abstract:
Ascorbate-conjugated liposomes and micelles, methods of making such liposomes and micelles, and methods of using such liposomes and micelles, such as for delivery of therapeutic and detection agents to the brain, are described.
Abstract:
Disclosed are improved pharmaceutical formulations for the delivery of RNA interference agents, such as antisense RNA, micro-RNA and siRNA. The formulations employ mixed micelles including amphipathic conjugates of the iRNA agents and amphipathic micelle-forming molecules with extended hydrophilic chains. Also disclosed are methods of using the pharmaceutical formulations to increase delivery of an iRNA agent to an intracellular target, and to decrease extracellular nuclease degradation of an iRNA agent in the formulations.
