摘要:
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 to enhance PO2 in hypoxic tumors.

摘要:
Novel monocyclic macrocyclic compounds having nitrogen bridgehead atoms and having in the hydrocarbon bridging chains at least two additional hetero atoms selected from the group consisting of sulfur, oxygen, and nitrogen, when admixed with a compatible cation-donor compound form stable cation-containing macrocyclic complexes which, in turn, can be conveniently dissociated by addition of acid or a quaternizing agent. The novel macrocyclics are valuable for use in the same way and for the same purposes as chelating agents.

摘要:
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.
