Patents by Inventor Yosi Shamay

Yosi Shamay 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: 10947275
    Abstract: The caged cell-penetrating peptide (cCPP) conjugates of this invention are ideal for intracellular delivery of a broad variety of cargoes including various nanoparticle pharmaceutical carriers (liposomes, micelles, microparticles, nanoparticles, polymer-conjugates). The conjugates comprise a detectable agent or a therapeutic agent, and the conjugates provide a novel strategy for site-specific delivery of the same to appropriate tissues in the subject. Versatile application of the conjugates in diagnostics and imaging is described.
    Type: Grant
    Filed: November 30, 2018
    Date of Patent: March 16, 2021
    Assignee: Ben-Gurion University of the Negev Research and Development Authority

  • Patent number: 9867884
    Abstract: The site-specific expression of selectins on endothelial cells of blood vessels during angiogenesis provides an opportunity to target anti-cancer drugs to the vascular endothelium to extend the range of the therapeutic effect. This invention describes an innovative drug targeting strategy for the selective delivery of the anticancer drugs to endothelial cells by means of polymer-drug conjugates modified with a carbohydrate ligand for the vascular selectins. A model chemotherapeutic drug, doxorubicin, and the E-selectin ligand, sLex, are attached to a biocompatible polymer (HPMA). The selective binding, cellular uptake, intracellular fate, and cell cytotoxicity of the polymer-bound drug are investigated in human endothelial cells.
