Novel organometallic compounds for binding amyloid are described. Methods using such compounds for determining by imaging the localization or quantification of amyloid fibrils in a mammal, for diagnosing the degree of progression of Alzheimer's disease in a mammal, for monitoring the response to a therapy in a mammal having Alzheimer's disease, for identifying an agent useful for treating Alzheimer's disease, for treating Alzheimer's disease, and for detecting the presence of the infectious form of the prion protein, are also described.

This ligand complexestechnetium(V) in its neutral oxo form. A biphenyl-containing building block was conjugated to the protected ligand, and the product was coupled to the relevant aromatic compounds. Rhenium oxo complexes, which are isosteric, but nonradioactive, analogues of the potential imaging agent technetium oxo complexes, were synthesized. These complexes bound to Abeta amyloid fibrils produced
