  • Patent number: 7160910
    Abstract: The provides compounds for the treatment of sickle-cell disease. In particular, the invention provides 5-membered heterocyclic anti-sickling agents that are highly effective and non-toxic, and methods for their use. The compounds include analogues and derivatives of naturally occurring occurring 5-hydroxymethyl-2-furfuraldehyde, 5-Ethyl-2-furfuraldehyde, 5-Methyl-2-furfuraldehyde, and 2-furfuraldehyde, and prodrug forms of the compound.
    Type: Grant
    Filed: December 3, 2003
    Date of Patent: January 9, 2007
    Assignee: Xechem International, Inc.

  • Patent number: 7119208
    Abstract: Compounds for the treatment of sickle-cell disease, and methods for their use are provided. The compounds have a dual mode of action. First, binding of the compounds to hemoglobin increases the oxygen affinity of both normal and sickle hemoglobin. Secondly, binding of these compounds to the N-terminal amino acid of sickle hemoglobin results in destabilization of potential contacts between sickle hemoglobin molecules, preventing polymerization and the formation of fibrous precipitates of the sickle hemoglobin. The compounds are also useful for inducing hypoxia, e.g. to augment cancer treatments.

  • Patent number: 6534501
    Abstract: Chemical structures have been identified which allosterically modify pyrvate kinase and inhibit enzymatic activity. These compounds can be used as pharmaceuticals in the treatment of a wide variety of diseases and disorders where influencing metabolic processes is beneficial, such as the glycolytic pathway, all pathways which use ATP as an energy source, and all pathways which involve 2,3-diphosphoglycerate related to the delivery of oxygen by modifying hemoglobin's oxygen affinity, treatments of tumor and cancer and Alzheimer's disease (AD).

  • Patent number: 5432191
    Abstract: A family of compounds has been found to be useful for right-shifting hemoglobin towards a low oxygen affinity state. The compounds are capable of acting on hemoglobin in whole blood. In addition, the compounds can maintain the oxygen affinity in blood during storage and can restore the oxygen affinity of outdated blood.
