  • Publication number: 20120035137
    Abstract: Inositol-tripyrophosphate is an allosteric effector of hemoglobin due to its ability to cross the plasma membrane of red blood cells and deliver oxygen to solid tumors, by lowering the oxygen affinity of the hemoglobin of red blood cells. The present invention is directed to the use of inositol-tripyrophosphate to reduce hemoglobin's affinity for oxygen in circulating red blood cells. The present invention is further directed to the use of inositol-tripyrophosphate to inhibit angiogenesis and enhance radiation sensitivity of hypoxic tumors. The present invention is further directed to the use of inositol-tripyrophosphate for the treatment of various types of cancers, Alzheimer's disease, stroke and osteoporosis.

  • Publication number: 20110294732
    Abstract: The present invention provides methods and compositions to replace up to 90% of erythropoietin use in the treatment of anemias and hypoxias. The method employs acid and salt forms of inositol-tripyrophosphate (ITPP) isomers to shift the P50 value of hemoglobin, thereby improving the rate and efficiency of oxygenation by blood even when red blood cell counts are low. Indications for the new method include anemias and hypoxia arising from infection, chemotherapy, premature birth, altitude change, compromised lung or heart function, aplastic anemia and anemia associated with a myelodysplastic syndrome, and other causes.
