  • Patent number: 8628771
    Abstract: Therapeutic methods for inhibiting the growth of preneoplastic/neoplastic vertebrate cells that abnormally express MN protein are disclosed. Screening assays are provided for identifying compounds, preferably organic compounds, preferably aromatic and heterocylic sulfonamides, which inhibit the enzymatic activity of MN/CA IX and that are useful for treating patients with preneoplastic/neoplastic disease. Further, the CA IX-specific inhibitors when labeled or linked to an appropriate visualizing means can also be used diagnostically/prognostically for preneoplastic/neoplastic disease, and for imaging use, for example, to detect hypoxic precancerous cells, tumors and/or metastases, by selectively binding to activated CA IX, preferably CA IX activated under hypoxic conditions, and not to inactive CA IX. Such detection of hypoxic conditions can be helpful in determining effective treatment options, and in predicting treatment outcome and the prognosis of disease development.
