Patents by Inventor David Hirsch Perlmutter

David Hirsch Perlmutter has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • 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.

  • Publication number: 20170049783
    Abstract: The present invention relates to methods of treatment of clinical disorders associated with protein polymerization comprising administering, to a subject, an effective amount of carbamazepine, oxcarbazepine or another carbamazepine-like compound. It is based, at least in part, on the discovery that, in cells having a genetic defect in ?1-antitrypsin, carbamazepine was able to decrease levels of the mutant protein. Furthermore, carbamazepine reduced the hepatic load of mutant ?1-antitrypsin and the toxic effect of that mutant protein accumulation, hepatic fibrosis, in vivo using a mouse model of the disease. As patients having this defect in ?1-antitrypsin exhibit toxic accumulations of the protein, treatment according to the invention may be used to ameliorate symptoms and signs of disease.
