摘要： Provided is a predistortion apparatus which performs predistortion by reflecting a memory effect when linearizing an output of a nonlinear device using a wideband signal. The predistortion apparatus includes a predistortion unit and a coefficient extraction unit. The predistortion unit selects and outputs one of outputs of the sub-predistorters as an output signal according to intensity of an input signal. The coefficient extraction unit selects one of a plurality of coefficient extractors according to intensity of a nonlinear signal which is generated in response to the output signal, extracts a plurality of predistortion coefficients with the nonlinear signal and the output signal, and delivers the extracted predistortion coefficients to the predistortion unit. Accordingly, the memory effect is reflected even when the input signal is a wideband signal.

The tricarbonyl technetium-99m or rhenium-188 labeled cyclic RGD derivatives of the present invention has a high subnanomolar affinity to integrin αvβ3 (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 αvβ3 because of a substantially low intake into the liver and intestines, compared to existing known radioactive isotope labeled cyclic RGD derivatives. These results show that the rhenium-188 labeled derivative, a therapeutic nuclide using the same precursor as used in the technetium-99m labeling, effectively inhibits the growth of a tumor and demonstrates therapeutic efficacy when administered via tail vein injection to an animal model bearing tumor, compared to a case where only saline has been injected, thereby making it useful as a medicine for the diagnosis or treatment of angiogenesis-related diseases.
