Specifically, this invention pertains to a transition metal catalyst which has stability under high temperature solution polymerization at 120˜250° C., in which a cyclopentadiene derivative and an electron donating substituent, both of which are bonded to a Group IV transition metal acting as a central metal, are crosslinked through a silyl derivative substituted with a cyclohexyl, to a catalyst system including such a transition metal catalyst and an aluminoxane cocatalyst or a boron compound cocatalyst, and to a method of producing an ethylene homopolymer or an ethylene copolymer with α-olefin, having high molecular weight, using the catalyst system under conditions of high-temperature solution polymerization. The catalyst according to this invention has excellent thermal stability and compatibility with a paraffin hydrocarbon solvent and thus is effective in the production of an ethylene homopolymer or an ethylene copolymer with α-olefin having various properties in commercial polymerization processes.

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.
