    摘要: We disclose methods of detecting histone deacetylase activity in a mammal by administering to the mammal a compound comprising at least one atom having a nucleus detectable by magnetic resonance spectroscopy, wherein the compound is a substrate of histone deacetylase; and observing the compound or a cleavage product thereof in at least a portion of the body of the mammal by magnetic resonance spectroscopy (MRS). We also disclose methods of detecting histone deacetylase activity in a mammal by administering to the mammal a compound comprising at least one positron-emission-decaying radioisotope, wherein the compound is a substrate of histone deacetylase; and observing the compound or a cleavage product thereof in at least a portion of the body of the mammal by positron emission tomography (PET). We also disclose compounds useful as histone deacetylase substrates.

    摘要: 2′-Deoxy-2′-[18F]-labeled and 3′-deoxy-3′-[18F]-labeled purine nucleoside analogs such as [18F]-FAA and [18F]-FXA have been found to have desirable properties for use as imaging agents. The analogs are particularly useful for in vivo imaging of biological material including organ tissues (e.g., heart, liver, brain and kidneys) and tumors. Methods for the preparation of the [18F]-FAA and [18F]-FXA are also provided.
