The invention described herein pertains to folate-receptor targeted agents comprising therapeutic agents useful for the treatment of inflammatory disease, including folate-receptor targeted liposomes (folate-targeted liposomes) containing entrapped therapeutic agents and folate-receptor targeted dendrimers conjugated to therapeutic agents (folate-targeted dendrimer conjugates), useful for the treatment of inflammatory disease, including auto-immune disease, as well as to folate-targeted liposomes containing entrapped imaging agents and dendrimer conjugates conjugated to imaging agents, for use in the diagnosis and monitoring of treatment in such disease.

Disclosed is a reagent for prothrombin time measurement, wherein the reagent contains a liposome composition containing a first liposome having a phospholipid layer, a second liposome having a phospholipid layer of a different composition from that of the first liposome, and tissue factor, wherein the tissue factor is associated with the phospholipid layer of at least one of the first liposome and the second liposome; the first liposome contains a phosphatidylcholine compound, a phosphatidylethanolamine compound, and a phosphatidylserine compound; and the second liposome contains at least one phospholipid selected from the group consisting of a phosphatidylcholine compound and a phosphatidylethanolamine compound.

Readily available hydrophilic and small organofluorine moieties were condensed via “click chemistry” to generate nonionic hydrophilic fluorinated molecules with unique .sup.19F MR signatures. These were used to fabricate stable liposome formulations for imaging various tissue types. This approach was tailored to exploit the broad spectrum of organic .sup.19F molecular species and to generate probes with distinct .sup.19F MRI signatures for simultaneous assessment of multiple molecular targets within the same target volume.

A method and system that is directed to the local delivery of growth factors to the mammalian CNS to treat CNS disorders associated with neuronal death and/or dysfunction is described.

The invention relates to a kit for preparation of target radiopharmaceuticals, a method of using the kit to prepare target radiopharmaceuticals and use of the target radiopharmaceuticals. The target radiopharmaceuticals comprise a radio-nuclear loading on liposome and inhibit the tumor growth and metastatic progression of head and neck cancer, lung cancer and brain cancer. The radiopharmaceuticals may be used for treating the mentioned cancers.

The disclosure is directed to method of inhibiting cancer cell growth by contacting cancer cells with a dose of an anti-cancer agent that is divided equally between a nanoparticle carrier encapsulating the anti-cancer agent and antibody carrier that binds to a cancer-specific receptor and is conjugated to the same anti-cancer agent.

Lipid-based nanocarriers (liposomes) loaded with a chemotherapeutic agent and exhibiting interstitial drug release and intratumoral adhesion are disclosed. The lipid-based nanocarriers disclosed herein include an ‘adsorptive/adhesive switch’ on the nanocarriers surface with the aim to increase the tumor residence times of the drug delivery nanocarriers and to slow down their tumor clearing kinetics. The switch is designed to promote nanoparticle adsorption on cancer cells and/or the extracellular matrix (ECM) while keeping their internalization by cells to a minimum. This approach of drug delivery is key for interstitial release of highly-diffusive forms of therapeutics.

Described herein are compositions comprising liposome-based nanocarriers and associated drugs that selectively target bone marrow, minimize tumor delivery, and maintain high drug concentrations in bone marrow when compared to conventional systemic delivery. The compositions also selectively target lymph nodes and other reticuloendothelial system organs (e.g., spleen, e.g., liver), while minimizing delivery to the tumor in order to deliver drugs that prevent bone marrow suppression (BMS) or aid recovery post exposure to radiation. There are a wide range of scenarios for which such radiation protection is useful, e.g., protection from radiation delivered as part of cancer therapy, radiation from weapons, radiation from materials at a nuclear power plant or nuclear waste site, natural radiation in outer space (e.g., for astronauts), and the like. The described compositions are stable for prolonged periods of time, in some cases over a year in a kit formulation.

It is therefore the objective of the present invention to provide minigastrin derivates which further improve the accumulation in CCK-2 receptor positive tumours by simultaneously very low accumulation in other organs, e.g. the kidneys. This objective is achieved according to the present invention by a minigastrin derivate having the formula: X-Z-Ala-Tyr-Gly-Trp-Met-Asp-Phe-NH.sub.2 (Y), wherein at least one of the connecting or terminal amide bonds between, before or after the amino acids of the sequence Z, Ala, Tyr, Gly, Trp, Met, Asp, Phe and NH.sub.2 or Y (C-terminal) is replaced by a 1,4-disubstituted or a 1,5-disubstituted 1,2,3-triazole, while X stands for a chemical group attached to the peptide for the purpose of diagnostic and/or therapeutic intervention at CCK-2 receptor relevant diseases, Y stands for C-terminal modifications of the peptide, such as amide, primary and secondary amides, free carboxylic acids and carboxylic ester derivatives including but not limited to amides and esters derived from linear or branched alkyl-,alkenyl-, alkynyl- aromatic-, and heterocyclic alcohols, and Z stands for a linker or DGlu* wherein DGlu* stands for a chain of DGlu having 1 to 6 repetitions (-DGlu-to-DGlu-DGlu-DGlu-DGlu-DGlu-DGlu-). These minigastrin derivates have a high specific internalization, excellent IC.sub.50 values and sufficient plasma stability.
