PSMA imaging agents

Compounds for targeting and agents for imaging, Prostate-specific membrane antigen (PSMA) are disclosed. Methods of synthesizing compounds and imaging agents, as well as methods for imaging PSMA are also disclosed. The imaging agents disclosed are suitable for PET and SPECT imaging.

The present application is directed to radiolabeled cyclic polyazapeptides, pharmaceutical compositions comprising radiolabeled cyclic polyazapeptides, and methods of using the radiolabeled cyclic polyazapeptides. Such polyazapeptides can be used in imaging studies, such as Positron Emitting Tomography (PET) or Single Photon Emission Computed Tomography (SPECT).

Cyclic azapeptides as integrin markers and methods of using

Provided herein are compounds and compositions which comprise the formulae as disclosed herein, wherein the compound is an amyloid binding compound. An amyloid binding compound according to the invention may be administered to a patient in amounts suitable for in vivo imaging of amyloid deposits, and distinguish between neurological tissue with amyloid deposits and normal neurological tissue. Amyloid probes of the invention may be used to detect and quantitate amyloid deposits in diseases including, for example, Down's syndrome, familial Alzheimer's Disease. In another embodiment, the compounds may be used in the treatment or prophylaxis of neurodegenerative disorders. Also provided herein are methods of allowing the compound to distribute into the brain tissue, and imaging the brain tissue, wherein an increase in binding of the compound to the brain tissue compared to a normal control level of binding indicates that the mammal is suffering from or is at risk of developing a neurodegenerative disease.

Imaging agents useful for identifying AD pathology

The present application discloses methods for identifying inhibitors with high binding-affinity for the carbonic anhydrase-IX (CA-IX) enzyme using click chemistry and uses the candidates thereof as positron emission tomography (PET) imaging agents.

Development of molecular imaging probes for carbonic anhydrase-IX using click chemistry

Cyclic azapeptides as integrin markers

The present invention relates to novel radioactively labeled bioreducible tracers of Formula I useful for detecting hypoxic tumors or ischemic tissue in vivo. In one embodiment, the tracers consist of a 2-nitroimidazole moiety, a triazole, metabolically stable linker with pharmacokinetics enhancing substituents, and a radioisotope. The preferred in vivo imaging modality is positron emission tomography. 

Nitro-imidazole hypoxia imaging agent

Disclosed herein are novel radiolabeled nucleosides and methods for detecting cellular proliferation in a mammal, the method comprising administrating an effective amount of a radiolabeled nucleoside; the method comprising: a) administering to the mammal a diagnostically effective amount of the nucleoside to the mammal; b) allowing the nucleoside to distribute into the effective tissue; and c) imaging the tissue, wherein an increase in binding of the compound to tissue compared to a normal control level of binding indicates that the mammal is suffering from a disease involving cellular proliferation.
