    摘要: 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.

    摘要: Chemical compounds which interact inside the central water cavity of hemoglobin and bridge between the two .alpha. subunits can be used to allosterically modify hemoglobin towards tense and relaxed states. The functional groups employed are aldehydes and carboxylic acids, wherein the aldehydes form covalent bonds (schiff base) with amino acid residues of hemoglobin and the carboxylic acids form ionic bonds with amino acid residues of hemoglobin. Particularly useful compounds within the practice of this invention bond to the n-terminal valine of one .alpha. subunit of hemoglobin, and the lysine 99 and/or arginine 141 of the other .alpha. subunit.

    摘要: Methods which increase the bioavailability of beneficial gases in the circulatory system are provided. The methods involve administering agents that changes the binding affinity of a medicinal gas such as NO, CO, H2S, N2O, SO, SO2 and O2 for Hb and/or hemoglobin based oxygen carriers (HBOCs). The change results in increased release of gases carried by Hb and HBOCs. As a result, the concentration of the OH gases in circulation is raised, and they are more available to exert their beneficial effects, e.g. in the treatment of disease or conditions caused by low levels of the gases. The methods are optionally used together with administration of medicinal gases and/or administration of HBOCs and/or other non-HBOC gas carriers such as PFC, and as (or in conjunction with) diagnostic methods.
