| 摘要 |
The present invention provides novel radiopharmaceuticals comprising one to three pentapeptides, X1X2X3X4X5, independently attached to a metal chelator or bonding moiety, Ch, to which is attached a Tc-99m, Re-186, or Re-188, optionally further comprising a linking group, Ln, between-the peptides and the chelator or bonding moiety. The pentapeptide sequence binds to the tuftsin receptor and is attached at the N-terminus to Ln or Ch. These radiopharmaceuticals are useful for the diagnosis of infection and inflammation, reagents and kits useful for preparing the radiopharmaceuticals, methods of imaging sites of infection and/or inflammation in a patient, and methods of diagnosing diseases associated with infection or inflammation in patients in need of such diagnosis. |
