  • 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.

  • Publication number: 20040113362
    Abstract: A board game for teaching pattern recognition. In one embodiment, the present invention teaches DNA concepts wherein patterns identified on playing cards represent a sequential biocode pattern and a plurality of game pieces represent biocodes differentiated by shape and color. Corresponding biocodes represent base pairs bound together to form the helix structure of DNA. Preferably, pattern recognition is taught utilizing a simple story line such as deep-space travelers having to repair a spaceship, by having to match a sequential pattern with game pieces (biocodes) to retrieve a spaceship part, in order to escape a distant planet.

  • Patent number: 5661182
    Abstract: Drug compounds are used as allosteric modifiers of hemoglobin present in red blood cells. The compounds bind to only a single pair of symmetry related sites in the central water cavity of hemoglobin at the Lys 99.alpha., Arg 141.alpha., and Asn 108 .beta. residues. When one of the drug compounds is bound to hemoglobin, it will join three separate sub-units of the hemoglobin molecule and stabilize the hemoglobin in a lower oxygen affinity state. Because the compounds used in this method are either not bound by serum albumin or only interact to small degrees with serum albumin, the compounds are active in whole blood and in vivo. The process of allosterically modifying hemoglobin towards a low oxygen affinity state in whole blood and in vivo could be used in a wide variety of applications including in treatments for ischemia, heart disease, wound healing, Alzheimer's, depression, schizophrenia, adult respiratory distress syndrome (ARDS), etc.
