Novel compounds and pharmaceutical compositions having MMP inhibitory activity are disclosed, which have been found to be particularly useful in the prevention, treatment and diagnostic imaging of diseases associated with an unpaired activity of MMP, amongst others MMP-2, MMP-8, MMP-9 and/or MMP-13 to name a few. The compounds of the present invention are useful for the prevention, the treatment and the in vivo diagnostic imaging of a range of disease states (inflammatory, malignant and degenerative diseases) where specific matrix metalloproteinases are known to be involved.

Compounds with matrix-metalloproteinase inhibitory activity and imaging agents thereof

Disclosed here in are compounds and methods of diagnosing Alzheimer's Disease or a predisposition thereto in a mammal, the method comprising administering to the mammal a diagnostically effective amount of a radiolabeled compound, wherein the compound is selected from the group consisting of radiolabeled carbazoles and derivatives thereof and triazoles derivatives, 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 Alzheimer's Disease.

Imaging agents for detecting neurological dysfunction

Imaging agents of formulas (I)-(V) and methods for detecting neurological disorders comprising administering to a patient in need compounds of formulas (I)-(V) capable of binding to tau proteins and &#x3b2;-amyloid peptides are presented herein. The invention also relates to methods of imaging A&#x3b2; and tau aggregates comprising introducing a detectable quantity of pharmaceutical formulation comprising a radiolabeled compound of formulas (I)-(V) and detecting the labeled compound associated with amyloid deposits and/or tau proteins in a patient. These methods and compositions enable preclinical diagnosis and monitoring progression of AD and other neurological disorders.

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

Disclosed here in are compounds and methods of diagnosing Alzheimer's Disease or a predisposition thereto in a mammal, the method comprising administering to the mammal a diagnostically effective amount of a radiolabeled compound, wherein the compound is selected from the group consisting of radiolabeled flavones, coumarins, carbazoles, quinolinones, chromenones, imidazoles and triazoles derivatives, 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 Alzheimer's Disease.

The present disclosure provides methods for treating cancer in a patient in need of such treatment, the method includes prequalifying a patient's therapeutic treatment by performing a molecular imaging procedure to the patient using a labeled biomarker specific for a cancer target at the tumor site; and administering a therapeutic effective amount of a compound comprising a targeting agent linked to a chemotherapeutic or a targeting agent linked to an antibody.
