摘要:
A cell-based screen is reported can be used to identify specific receptor-binding compounds in a combinatorial library of peptoids (N-alkylglycine oligomers) displayed on beads. This strategy was applied to the isolation of Vascular Endothelial Growth Factor Receptor 2 (VEGFR2)-binding peptoids, which were optimized to create lead compounds with high affinity for VEGFR2. One of these peptoids was shown to be an antagonist of VEGF-VEGFR2 interaction and receptor function.
摘要:
Disclosed is the surprising discovery that aminophospholipids, such as phosphatidylserine and phosphatidylethanolamine, are specific, accessible and stable markers of the luminal surface of tumor blood vessels. The present invention thus provides aminophospholipid-targeted diagnostic and therapeutic constructs for use in tumor intervention. Antibody-therapeutic agent conjugates and constructs that bind to aminophospholipids are particularly provided, as are methods of specifically delivering therapeutic agents, including toxins and coagulants, to the stably-expressed aminophospholipids of tumor blood vessels, thereby inducing thrombosis, necrosis and tumor regression.

摘要:
Disclosed are antibodies that specifically inhibit VEGF binding to only one (VEGFR2) of the two VEGF receptors. The antibodies effectively inhibit angiogenesis and induce tumor regression, and yet have improved safety due to their specificity. The present invention thus provides new antibody-based compositions, methods and combined protocols for treating cancer and other angiogenic diseases. Advantageous immunoconjugate and prodrug compositions
