  • Patent number: 9844605
    Abstract: The present invention relates to methods and compositions for high content drug screening in Caenorhabditis elegans which may be used to identify compounds that treat disorders associated with protein aggregation. It is based, at least in part, on the discovery that Caenorhabditis elegans, genetically modified to create a model system for disorders of protein aggregation, could be used, in a high throughput screening system, to identify agents that reduce the amount of aggregated protein.
    Type: Grant

  • Patent number: 9820990
    Abstract: The present invention relates to methods of treatment of clinical disorders associated with protein aggregation comprising administering, to a subject, an effective amount of an anti-protein aggregate (“APA”) compound selected from the group consisting of pimozide, fluphenazine (e.g., fluphenazine hydrochloride), tamoxifen (e.g., tamoxifen citrate), taxol, cantharidin, cantharidic acid, salts thereof and their structurally related compounds. It is based, at least in part, on the discovery that each of the aforelisted compounds were able to promote degradation of aggregated ATZ protein in a Caenorhabditis elegans model system. According to the invention, treatment with one or more of these APA compounds may be used to ameliorate the symptoms and signs of AT deficiency as well as other disorders marked by protein aggregation, including, but not limited to, Alzheimer's Disease, Parkinson's Disease, and Huntington's Disease.
