  • Publication number: 20180194737
    Abstract: In certain embodiments hydantoin compounds are provided herein that are effective to inhibit BACE activity against APP. Without being bound to a particular theory, it is believed the activity of the hydantoins identified herein appears to be associated with binding to BACE and/or to APP particularly when these moieties form a BACE/APP complex. Accordingly, it is believed the compounds described herein represent a new class of compounds designated herein as APP-Binding-BACE Inhibitors (ABBIs) and provide a new mechanism to modulate APP processing. The hydantoins described herein appear to show improved brain permeability and functional BACE inhibition.

  • Publication number: 20170226059
    Abstract: A link between ApoE4 allele and sirtuins expression level is identified that is believed to be associated with elevated risk for the promotion of processing of amyloid precursor protein (APP) by the non-amyloidogenic pathway in a mammal leading to elevated risk for Alzheimer's disease. Compounds are identified that upregulate sirtuins (e.g., SirT1) expression levels and appear to be useful in the treatment and/or prophylaxis of MCI and/or Alzheimer's disease.

  • Patent number: 9534016
    Abstract: In certain embodiments compositions are provided that comprise a pentapeptide comprising the formula: C1-X2-X3-X4-C5 where C1 and C5 are independently selected cysteines or cysteine analogues, or other amino acids with sidechains suitable for cyclization, where the cysteines or cysteine analogs are attached to each other by a linkage that does not comprise X2, X3, and X4; where X2, X3, and X4 are independently selected amino acids; and the peptide, when administered to a cell alters APP signaling and/or switches APP processing from aberrant to normal. The compositions mitigate amyloid plaque formation.

  • Publication number: 20110281752
    Abstract: Disclosed are various forms of an active, isolated ?-secretase enzyme in purified and recombinant form. This enzyme is implicated in the production of amyloid plaque components which accumulate in the brains of individuals afflicted with Alzheimer's disease. Recombinant cells that produce this enzyme either alone or in combination with some of its natural substrates (?-APPwt and ?-APPsw) are also disclosed, as are antibodies directed to such proteins. These compositions are useful for use in methods of selecting compounds that modulate ?-secretase. Inhibitors of ?-secretase are implicated as therapeutics in the treatment of neurodegenerative diseases, such as Alzheimer's disease.
