  • Publication number: 20130064766
    Abstract: The present invention relates to tricarbonyl technetium-99m or rhenium-188 labeled cyclic RGD derivatives, a preparation method thereof, and a pharmaceutical composition containing the derivative as an active ingredient for use in the diagnosis or treatment (radiotherapy) of angiogenesis-related diseases. The tricarbonyl technetium-99m or rhenium-188 labeled cyclic RGD derivatives of the present invention has a high subnanomolar affinity to integrin ?v?3 (also called as a vitronectin receptor) that is activated in an angiogenic action induced by a tumor, reflects a high tumor image of the tricatvonyl technetium-99m labeled cyclic RGD derivative after initial intake in an animal in which cancer cells are transplanted, and acts exclusively upon cancer cells having selectively activated integrin ?v?3 because of a substantially low intake into the liver and intestines, compared to existing known radioactive isotope labeled cyclic RGD derivatives.
