  • Compositions and methods for inhibiting deoxyhypusine synthase and the growth of cells
    Patent number: 5344846
    Abstract: Compositions and methods for the treatment of mammalian cells to inhibit cell growth, especially for inhibiting the proliferative cell growth associated with malignant and non-malignant disease, are provided. More particularly, a deoxyhypusine synthase inhibitor, typically, a mono- or bisguanyl diamine or polyamine, is administered to the cells.Also provided by this invention are diagnostic methods and kits for screening the cells of a patient to determine the effect of the deoxyhypusine synthase inhibitor on proliferation of the cells.
