Provided is a composition of antiviral agent for use in prophylaxis or treatment against pathogenic infection. The liposomal antiviral agent of the composition has a liposome and an antiviral agent entrapped in the liposome. The antiviral agent has been stably encapsulated in the liposome, and the resulting liposomal antiviral agent is proven to be stably aerosolized or nebulized for administration via the inhalation route to treat a subject in need thereof with reduced side effect.

The present invention relates to a target-aiming drug delivery system for diagnosis and treatment of cancer containing liposome labeled with peptides which specifically targets interleukin-4 receptors, and a manufacturing method thereof. The liposome which contains anticancer drugs labeled with IL4RPep peptides prepared in accordance with the present invention can deliver drugs to cancer cells in which IL-4 receptors are overexpressed by IL4RPep peptides which specifically bind to IL-4 receptors, and the drug delivery can recognize cancer cells specifically by a label. Thus, IL4RPep peptides can increase the effect of drugs only on cancer tissues and at the same time significantly reduce the side effects on normal tissues, which makes possible in vivo(molecular) imaging and early diagnosis of tumors. Therefore, the liposome which contains anticancer drugs labeled with IL4Pep peptides of the present invention can be applied, as the target-aiming drug delivery system, effectively to the diagnosis and treatment of cancers.

Compositions and methods for treating a viral infection may comprise use of a nanoparticle composition. A nanoparticle composition of the present disclosure may comprise a targeting moiety and/or anti-viral agent and reduces the infectivity of a virus for a host cell. A method of treating a viral infection may comprise administering a composition comprising a nanoparticle of the present disclosure, to a subject and reducing the infectivity of the virus for a host cell of the subject. The compositions may be administered via intranasal or systemic administration to treat or prevent a viral infection, for example a coronavirus infection.

The disclosure relates generally to polyglutamated antifolates, formulations containing liposomes filled with the polyglutamated antifolates, methods of making the polyglutamated antifolates and liposome containing formulations, and methods of using the polyglutamated antifolates and liposome containing formulations to treat hyerproliferative disorders (e.g., cancer) and disorders of the immune system (e.g., an autoimmune disease such as rheumatoid arthritis).

A composition for use in diagnostic and therapeutic applications includes a heteromultivalent nanoparticle or microparticle having an outer surface and a plurality of targeting moieties conjugated to the surface of the nanoparticle or microparticle, the targeting moieties includes a first activated platelet targeting moiety and a second activated platelet targeting moiety.

The invention relates to Cathepsin-binding compounds bound to a carrier comprising a diagnostic moiety, for use in the diagnosis of inflammatory diseases, and/or for use in the diagnosis of neoplastic diseases, wherein the Cathepsin-binding compound binds to inflammatory cells of the tumour stroma. The invention also relates to Cathepsin B-targeting compounds and Cathepsin B-binding and liposome-binding compounds.

The invention provides an improved lipid-based nanoparticle, which can be used to deliver a therapeutic agent to a subject, such as but not limited to a mammal, such as but not limited to a human. In certain embodiments, the nanoparticle of the invention has reduced aggregation properties as compared to those taught in the prior art.

Improved methods for manufacturing a non-viral delivery system comprising a liposome encapsulating an RNA using a microfluidic device and compositions for use therein are provided.

The present invention relates to a long-circulating liposome modified with c(RGD-ACP-K). The present invention pertains to the field of pharmaceutical preparations, in particular to the field of targeted pharmaceutical preparations. More specifically, the present invention relates to a long-circulating liposome, the surface of the liposome being modified with c(RGD-ACP-K), and the liposome comprising doxorubicin or a pharmaceutically acceptable salt thereof such as doxorubicin hydrochloride as an anti-cancer active agent. The long-circulating liposome can targetedly deliver the anti-cancer active agent into tumor neovascular endothelial cells and tumor cells and can prolong the circulation time of the liposome in vivo, thereby enhancing the therapeutic effect of anti-tumor medicaments.

The present invention relates to a carrier for delivering a substance to extracellular matrix-producing cells in the intestine, the carrier containing a retinoid as a targeting agent, and an agent for treating fibrosis of the intestine utilizing the carrier.
