  • Publication number: 20210041441
    Abstract: The present invention is directed to compounds, compositions and methods for modulating RAS family GTPases, in particular KRas, HRas and NRas GTPases. These GTPases are upregulated in cancer and in other tissue and represent appropriate targets for therapy. Methods for identifying the activity of compounds with respect to these and other GTPases in multiplex flow cytometry systems represents another aspect of this invention.

  • Patent number: 10822325
    Abstract: The present invention relates to compounds which have been discovered to be potent ligands (inhibitors) of human GLUT5 (glucose transporter type 5), a facilitative glucose transporter that transports fructose, and their use as ligands assays which can uncover additional ligands of GLUT5, having the potential for being used as drugs. In addition, the present invention is directed to compounds, chemical compositions and methods for treating disease states and conditions which are mediated through GLUT5, including such disease states and conditions as GLUT5 deficiency syndrome, diabetes (type I and II), cancer, metabolic diseases including metabolic syndrome and fatty liver disease, among others.

  • Patent number: 9326974
    Abstract: A method of treatment and/or prevention of cancer comprises administering agents which cause increased intracellular granularity in cancer cells, at least in an amount sufficient to inhibit proliferation of such cells and preferably in an amount sufficient to lead to cancer cell death. The method is particularly directed to refractory cancer, particularly hormone refractory prostate cancer. The agents identified cause increased intracellular granularity in the cancer cells, and also convert adherent cancer cells to non-adherent cancer cells, leading to cancer cell death. Using the present invention, cancer cells undergo increased intracellular granularity at relatively low agent concentrations, while also inhibiting cell proliferation. Increased concentrations lead to conversion of adherent cancer cells to non-adherent cancer cells, then to cell death.

  • Publication number: 20150087886
    Abstract: This invention relates to novel cancer treatment compositions and associated therapeutic methods. More particularly, this invention relates in part to small chemical bifunctional inhibitors of DNA replication and repair proteins Metnase and/or Intnase (also termed Gypsy Integrase, Gypsy Integrease-1, Gypsy Retransposon Integrase 1, or GIN-1) that simultaneously damage DNA, and to a therapeutic method that utilizes the inhibitors to increase the effectiveness of cancer treatment protocols, including radiation therapy. In preferred embodiments, compounds, compositions and methods of treatment of the invention are used to treat a patient suffering from leukemia (e.g. acute myeloid leukemia (AML) and related cancers.

  • Publication number: 20090208493
    Abstract: Compounds disclosed which inhibit ABCB1 transporter protein are useful for treating diseases in which ABCB1 transporter protein mediates the disease state, including numerous cancers, including hematopoietic cancers, including various leukemias, especially T-lineage acute lymphoblastic leukemia, as well as cancerous tumors, especially forms which exhibit multiple drug resistance. Pharmaceutical compositions which comprise an inhibitor of ABCB1 transporter protein and at least one additional anticancer agent, optionally in combination with a pharmaceutically acceptable carrier, additive or excipient are another aspect of the present invention. A flow cytometry based, high-throughput screening (HST) assay that quantifies ABCB1 efflux is also disclosed. Methods of identifying inhibitors of ABCB1, ABCG2 and ABCC1 transporter proteins are also disclosed.
