A self-assembled nanostructure including an amphiphilic chitosan and a contrast agent compound is provided. The contrast agent compound is grafted to the amphiphilic chitosan. The chemical bonding between the amphiphilic chitosan and the contrast agent compound has a synergistic effect to further improve the contrasting ability of the contrast agent compound.

A polypeptide or multimeric polypeptide construct having the ability to bind to cMet or a complex comprising cMet and HGF, and methods for use are disclosed.

Peptides having activity as protein binding agents are disclosed. The peptides have the following structure (I):

##STR00001##

including stereoisomers, pharmaceutically acceptable salts and prodrugs thereof, wherein R, R.sup.1, L.sup.1, L.sup.2, G, M, Y.sup.1 Y.sup.2 and SEQ are as defined herein. Methods associated with preparation and use of such peptides, as well as pharmaceutical compositions comprising such peptides, are also disclosed.

Disclosed herein are compounds having activity as cell penetrating peptides. In some examples, the compounds can comprise a cell penetrating peptide moiety and a cargo moiety. The cargo moiety can comprise one or more detectable moieties, one or more therapeutic moieties, one or more targeting moieties, or any combination thereof. In some examples, the cell penetrating peptide moiety is cyclic. In some examples, the cell penetrating peptide moiety and cargo moiety together are cyclic. In some examples, the cell penetrating peptide moiety is cyclic and the cargo moiety is appended to the cyclic cell penetrating peptide moiety structure. In some examples, the cargo moiety is cyclic and the cell penetrating peptide moiety is cyclic, and together they form a fused bicyclic system.

An ophthalmic composition comprising Indigo Carmine, or Indigo Carmine and Trypan Blue, for identification of intraocular structures and membranes within the eye, and methods of delivering and using the same, for surgical treatments of the eye, including glaucoma and cataract surgery.

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.

Described herein are prostate specific membrane antigen (PSMA) binding conjugates that are useful for delivering therapeutic, diagnostic and imaging agents. Also described herein are pharmaceutical composition containing them and methods of using the conjugates and compositions. Also described are processes for manufacture of the conjugates and the compositions containing them.

The present application provides quinoline-3-carboxamide compounds covalently linked to a label for use in the diagnosis of an inflammatory disease at local site. The above mentioned compounds can be used to detect or image accumulation of S100A9 in the body of a subject at sites of inflammation, using in vivo non-invasive molecular imaging techniques for the detection of said compounds. Accordingly, labeled quinoline-3-carboxamide compounds can be applied to evaluate the risk of a subject of developing an inflammatory disease and to follow the progress of the disease.

Polymeric particles are provided for use in therapeutic and/or diagnostic procedures. The particles include poly[bis(trifluoroethoxy)phosphazene and/or a derivative thereof which may be present throughout the particles or within an outer coating of the particles. The particles may also include a core having a hydrogel formed from an acrylic-based polymer. Such particles may be provided to a user in specific selected sizes to allow for selective embolization of certain sized blood vessels or localized treatment with an active component agent in specific clinical uses. Particles of the present invention may further be provided as color-coded microspheres or nanospheres to allow ready identification of the sized particles in use. Such color-coded microspheres or nanospheres may further be provided in like color-coded delivery or containment devices to enhance user identification and provide visual confirmation of the use of a specifically desired size of microspheres or nanospheres.

The present invention relates to a novel delivery system for delivering therapeutic agents into living cells, and more particularly, to novel chemical moieties that are designed capable of targeting and/or penetrating cells or other targets of interest and further capable of binding therapeutic agents to be delivered to these cells, and to delivery systems containing same.
