摘要:
Embodiments of the present invention relates to compounds labeled with imaging agents that also are capable of binding lectin-like oxidized low-density lipoprotein (LOX-1). The labeled compounds are useful for the diagnosis and monitoring of diseases in which inflammation plays a role, such as various cardiovascular diseases including but not limited to atherosclerosis, vulnerable plaque, and coronary artery disease, as well as rheumatoid arthritis.
摘要:
Pharmaceuticals for enhanced delivery to a disease target comprises a pair of compounds. The first compound comprises a first oligopeptide conjugated to a first moiety for coupling with a diagnostic or therapeutic active agent. The second compound comprises a second oligopeptide conjugated to a targeting species having a targeting moiety capable of binding to a target. The second oligopeptide has a sequence that is complementary to a sequence of the first oligopeptide. The first and second oligopeptides can be complementary PNA sequences. The pharmaceuticals are administered into a subject in methods for diagnosing or treating a disease condition, or assessing the effectiveness of a treatment of the disease condition.
摘要:
There is provided a technique for conjugating one or more complexing agents with a targeting moiety, such as natural amino acids, unnatural amino acids, peptides, peptide nucleic acids, nucleotides, and analogs and derivatives thereof. The one or more complexing agents are conjugated at one or more free amino groups of the targeting moiety while the moiety is attached to a solid substrate.
摘要:
A set of compounds that includes an active-agent labeled species and a pretargeting conjugate is disclosed. The active agent-labeled species includes a ligand coupled to an active agent. The pretargeting conjugate includes a protein conjugated to a targeting species having a targeting moiety capable of binding to an in-vivo target or a biomarker produced by or associated with the target. The protein is substantially free of a cofactor. Also disclosed are methods of administering the pretargeting species and the active-agent labeled species to a subject for diagnosing or treating a disease condition, or assessing the effectiveness of a treatment of the disease condition.
摘要:
The present invention relates to the use of Heat Shock Proteins and fragments thereof as targeting ligand. The Heat Shock Protein may be labeled with imaging agents that are capable of binding lectin-like oxidized low-density lipoprotein (LOX-1) or may be attached to a therapeutic agent. The sequences are useful for the diagnosis and monitoring of diseases as well as means for internalizing signaling moieties and therapeutics.
摘要:
In some embodiments, the present invention is directed to novel targeted contrast agents for magnetic resonance imaging (MRI). The present invention is also directed to methods of making such targeted MRI contrast agents, and to methods of using such MRI contrast agents. Typically, such targeted MRI contrast agents provide enhanced relaxivity, improved signal-to-noise, targeting ability, and resistance to agglomeration. Methods of making such MRI contrast agents typically afford better control over particle size, and methods of using such MRI contrast agents typically afford enhanced blood clearance rates and biodistribution.

A set of compounds that includes an active-agent labeled species and a pretargeting conjugate is disclosed. The active agent-labeled species includes a ligand coupled to an active agent. The pretargeting conjugate includes a protein conjugated to a targeting species having a targeting moiety capable of binding to an in-vivo target or a biomarker produced by or associated with the target. The protein and the ligand are covalently attached. Also disclosed are methods of administering the pretargeting species and the active-agent labeled species to a subject for diagnosing or treating a disease condition, or assessing the effectiveness of a treatment of the disease condition.
摘要:
A method of labeling amino acid-containing compounds and derivatives thereof with a halide moiety comprises reacting a nucleophilic moiety on such compounds with a halogenated electrophilic compound. Radioactive halide-labeled amino acid-containing compounds can be targeted to diseased sites and provide a means to diagnose and/or treat the disease.

摘要:
Agents and methods for qualitative and quantitative analysis a protein complex or protein complexes using isotope-labeled symmetrical bifunctional crosslinkers and mass spectrometry are provided. Targeting moieties, cell permeability moieties, or affinity moieties, may be appended to the bifunctional crosslinkers. The isotope-labeled symmetrical bifunctional crosslinkers may be used in a kit or as a library.
