Haloperidol-associated stealth liposomes: a potent carrier for delivering genes to human breast cancer cells.
Sigma receptors are membrane-bound proteins that are overexpressed in certain human malignancies including breast cancer. These receptors show very high affinity for various sigma ligands including neuroleptics like haloperidol. We hypothesized that in associating haloperidol-linked lipid into the cationic lipid-DNA complex, we can specifically target and deliver genes to breast cancer cells th...
متن کاملSurface Engineering of Liposomes for Stealth Behavior
Liposomes are used as a delivery vehicle for drug molecules and imaging agents. The major impetus in their biomedical applications comes from the ability to prolong their circulation half-life after administration. Conventional liposomes are easily recognized by the mononuclear phagocyte system and are rapidly cleared from the blood stream. Modification of the liposomal surface with hydrophilic...
متن کاملRemote loading of preencapsulated drugs into stealth liposomes.
Loading drugs into carriers such as liposomes can increase the therapeutic ratio by reducing drug concentrations in normal tissues and raising their concentrations in tumors. Although this strategy has proven advantageous in certain circumstances, many drugs are highly hydrophobic and nonionizable and cannot be loaded into liposomes through conventional means. We hypothesized that such drugs co...
متن کاملDetecting infection and inflammation with technetium-99m-labeled Stealth liposomes.
UNLABELLED The performance of 99mTc Stealth liposomes was investigated in various rat models. METHODS Preformed polyethyleneglycol-containing liposomes with encapsulated reduced glutathione, were radiolabeled using the lipophilic 99mTc-HMPAO. The labeled liposomes were intravenously administered to rats with focal S. aureus or E. coli infection, or turpentine-induced inflammation. For compari...
متن کاملPharmacokinetics of stealth versus conventional liposomes: effect of dose.
Liposomes which substantially avoid uptake into the mononuclear phagocyte system (MPS), termed Stealth liposomes, have recently been formulated (Allen, T.M. and Chonn, A., (1987) FEBS Lett. 223, 42-46). The pharmacokinetics of stealth liposomes as a function of liposome dose and a comparison to conventional liposome pharmacokinetics, was the subject of the present study. We have examined the ti...
