The present disclosure provides peptide constructs for diagnostic imaging and therapeutic applications, using pegylated peptides which exhibit specific binding for a target molecule of interest, such as a biomarker of a disease or disorder.

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.

The present invention provides compounds that have motifs that target the compounds to cells that express integrins. In particular, the compounds have peptides with one or more RD motifs conjugated to an agent selected from an imaging agent and a targeting agent. The compounds may be used to detect, monitor, and treat a variety of disorders mediated by integrins.

The present subject matter relates to a non-invasive optical imaging method for monitoring early pathological events specific to Alzheimer's disease (AD), such as the development, amount and location of amyloid plaques. The ability to monitor such events provides a basis for, among other things, AD diagnosis, prognosis and assessment of potential therapies. In addition, the present subject matter introduces novel methods for treating AD and retinal ailments associated with AD. Aβ-plaque detection in living brains is extremely limited, especially at high resolution; therefore the present invention is based on studies focusing on the eyes as an alternative to brain-derived tissue that can be imaged directly, repetitively and non-invasively.

The invention relates to polymerized micelles of size inferior to 100 nm for in vivo diagnosis, in particular of cancer. The polymerized micelles of the invention comprise a diagnostic agent and an amphiphilic polymer obtainable by the polymerization of an amphiphilic monomer, said monomer comprising: a lipophilic chain comprising a polymerizable vinylic or diacetylenic group, and a hydrophilic head comprising a polyoxyethylene or polyoxypropylene chain. The invention finds application in the pharmaceutical field, in particular.

The problem to be solved is to provide an anti-human MUC1 antibody Fab fragment that is expected to be useful in the diagnosis and/or treatment of a cancer, particularly, the diagnosis and/or treatment of breast cancer or bladder cancer, and a diagnosis approach and/or a treatment approach using a conjugate comprising the Fab fragment. The solution is an anti-human MUC1 antibody Fab fragment comprising a heavy chain fragment comprising a heavy chain variable region consisting of the amino acid sequence represented by SEQ ID NO: 8 or 10, and a light chain comprising a light chain variable region consisting of the amino acid sequence represented by SEQ ID NO: 12, and a conjugate comprising the Fab fragment.

Embodiments of the synthesis, radiolabeling and biological applications of an activatable tracer that undergoes intramolecular cyclization and aggregation upon activation by cleavage of a blocking moiety are provided. The probes of the disclosure allow for target-controlled self-assembly of small molecules in living subjects for imaging and drug delivery. The aggregated nanoprobes of the disclosure may be detectable optically, by PET detection, magnetic resonance imaging, and the like depending on the detectable reporter attached to the nanoprobe.

The present invention relates to diagnostic and therapeutic agents comprising recombinant antibody fragments to bind a protein associated with cancer and methods of use of these diagnostic and therapeutic agents.

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.

An object of the present invention is to provide a cancer cell inhibitory drug, particularly a cancer stem-cell inhibitory drug, or a cancer stem-cell detection probe. The present invention provides a cancer cell inhibitory drug comprising at least one compound represented by general formula (1) as an active ingredient
