  • Patent number: 7112602
    Abstract: The invention provides new and useful analogs of 2-phthalimidinoglutaric acid. These analogs include DL-2-methyl-2-phthalimidinoglutaric acid and hydroxylated analogs of 2-phthalimidinoglutaric. The invention also provides processes for making these analogs. The invention also provides the two individual enantiomers of DL-2-methyl-2-phthalimidinoglutaric acid, (R)-(+)-2-methyl-2-phthalimidinoglutaric acid and (S)-(?)-2-methyl-2-phthalimidinoglutaric acid, and processes for separating these individual enantiomers from the racemate. Further, the invention provides methods for inhibiting angiogenesis and treating angiogenesis-associated diseases, including cancer and macular degeneration, by administering one or more of these compounds.

  • Patent number: 6946439
    Abstract: Compositions and methods effective in inhibiting abnormal or undesirable cell proliferation, particularly endothelial cell proliferation and angiogenesis related to neovascularization and tumor growth are provided. The compositions comprise a naturally occurring or synthetic protein, peptide, or protein fragment containing all or an active portion of the C-terminal portion of proteinase inhibitors such as TFPI. The methods involve administering to a human or animal the composition described herein in a dosage sufficient to inhibit cell proliferation, particularly endothelial cell proliferation. The methods are useful for treating diseases and processes mediated by undesired and uncontrolled cell proliferation, such as cancer, particularly by inhibiting angiogenesis. Administration of the composition to a human or animal having prevascularized, metastasized tumors is useful for preventing the growth or expansion of such tumors.

  • Patent number: 6734163
    Abstract: Compositions and methods for inhibiting cellular proliferation wherein the composition contains Tissue Factor Pathway Inhibitor (TFPI), a TFPI homolog, or an active fragment thereof. TFPI exhibits potent anti-proliferative activity on human and other animal cells, particularly endothelial cells. More particularly, the TFPI, TFPI homolog, and inhibitory fragment thereof may be combined with a pharmaceutically acceptable excipient or carrier and used to inhibit angiogenesis and angiogenesis-related diseases such as cancer, arthritis, macular degeneration, and diabetic retinopathy.
