Abstract: Though copper is elevated in the tumor tissue and plasma of patients with various malignancies, the molecular targets for copper binding agents in angiogenesis and tumor progression remain poorly understood. It is disclosed that one anti-angiogenic target for the copper binding agent tetrathiomolybdate is intracellular CuZn-superoxide dismutase (SOD1). A second generation tetrathiomolybdate analog, ATN-224, inhibits endothelial cell (EC) proliferation in vitro, binds to SOD1 and inhibits its activity without displacing bound copper ATN-224 can accumulate in ECs and inhibit CuZnSOD activity with an IC50 similar to the IC50 for EC proliferation, resulting in increased generation of intracellular reactive oxygen species. Inhibition of EC proliferation by ATN-224 in vitro is substantially reversed by a synthetic porphyrin SOD mimetic. Similar results were observed in vivo, where inhibition of angiogenesis by ATN-224 in a Matrigel plug model was also reversed by MnTBAP.

Abstract: Disclosed are deglycosylated fragments of a kringle 1-3 region of plasminogen, nucleotides encoding deglycosylated kringle 1-3 region proteins and antibodies specific for deglycosylated kringle 1-3 region proteins. The compositions of the present invention have increased antiangiogenic activity as compared to previously isolated kringle 1-3 region proteins. Also included in the present invention are methods of treating angiogenesis-associated diseases and conditions such as cancer using the compositions described herein.

Abstract: We have now discovered that partially deglycosylated vitamin D binding protein (DBP-maf) is anti-tumorigenic not wholly via an immune mechanism but in part via an antiangiogenic mechanism. Accordingly, the present invention relates to use of DBP-maf in the treatment of diseases associated with increased or abnormal angiogenesis and/or endothelial cell differentiation. Preferably, the DBP-maf is administered to the patient by sustained release or in pulses. Pulse therapy is not a form of discontinuous administration of the same account of a composition over time, but comprises administration of the same dose of the composition at a reduced frequency or administration of reduced doses.

Abstract: The invention provides for methods of reducing or inhibiting angiogenesis, tumor growth and endothelial cell proliferation by the administration of compositions containing fragments, conformations, biological equivalent, or derivatives of antithrombin III. The invention also provides for pharmaceutical compositions comprising a fragment, conformation, biological equivalent, or derivative of antithrombin III and methods of identifying novel inhibitors of tumor growth, endothelial cell proliferation, and/or angiogenesis. The invention also relates to compositions and methods for altering angiogenesis in a mammal, as well as to methods of treatment for disorders associated with angiogenesis (e.g., cancer).
