    摘要: Tracers that can be used for PET or SPECT imaging of the distribution of Pgp are disclosed. The tracers are metalloprobes that can comprise a radioactive metal ion such as 67Ga or 68Ga. Methods of synthesizing the tracers, and methods of imaging heart and other tissues are also disclosed. The tracers can be used to obtain high signal-to-background ratios for imaging tissues in vivo such as heart or tumor tissue. In various embodiments, disclosed tracers can exhibit, a) enhanced first pass extraction into heart tissue compared to presently available probes, b) linearity with true blood flow, c) enhanced detection of myocardial viability compared to presently available probes, d) reduced liver retention compared to presently available probes, and e) more efficient clearance from non-cardiac and adjoining tissues compared to presently available probes.

    摘要: Methods of imaging distribution of myeloperoxidase activity in a subject are disclosed. These methods include the use of bioluminescent substrates, including luminol and wavelength-shifted analogues of luminol. Bioluminescent myeloperoxidase substrates that emit light at longer wavelengths compared to luminol are shown to be useful for imaging myeloperoxidase activity in vivo. The disclosed methods can be used for imaging sites of inflammation and other pathological conditions associated with abnormal levels of MPO activity in vivo. Methods of synthesis of luminol analogues are also disclosed.

    摘要: Novel blood-brain barrier permeant amyloid-targeting peptides and peptide conjugates are described. The peptide conjugates include a radioisotope or other label in a stable complex that translocates across brain capillary endothelial cell monolayers. The labeled peptide conjugate binds to amyloid plaques (Aβ) associated with Alzheimer's disease, and is useful for the targeted delivery of therapeutic and diagnostic molecules into the brain.
