Abstract:
A new class of quinoline compounds is useful for the detection and treatment of Alzheimer's disease and other neurodegenerative diseases such as amyloidoses and tauopathies. The compounds can be synthesized in radiolabeled form for use as imaging agents, which can be used for early detection of aggregates in the brain or other tissues prior to onset of symptoms, allowing early therapeutic intervention. The compounds are also useful for the prevention and treatment of such diseases.
Abstract:
The present invention is directed to a novel compound of Formula 1 wherein the radiolabeled compound of Formula 1 is capable of being used as a radiotracer in PET imaging of a targeted localized tissue and targeted radionuclide therapy of one or more conditions that may be regulated or normalized via inhibition of transporter such as Pgp, BCRP or MRP I. The novel compounds of Formula 1 can also be used as substrates for binding with one or more ABC transporters. In particular, the present invention aids in diagnosis and therapeutic treatment of MDR disorders in all forms of cancers and neurological disorders of the central nervous system. The present invention further provides methods of preparation of compounds of Formula 1 and novel intermediates used in the preparation of compounds of Formula 1.
Abstract:
The invention relates to water soluble 18 F-prosthetic groups and the synthesis and use of 18 F-labeled biological molecules containing the 18 F-prosthetic groups for imaging various processes within the body, for detecting the location of molecules associated with disease pathology, and for monitoring disease progression are disclosed.
Abstract:
"Reversed" carbamate based scaffolds that have high binding affinity to PSMA are disclosed. These scaffolds can be radiolabeled and used for imaging cells and tumors that express PSMA or for cancer radiotherapy. These compounds also can comprise a fluorescent dye and be used for imaging cells and tumors that express PSMA or for photodynamic therapy.
