Patents by Inventor Yosef Salitra

Yosef Salitra 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).

  • Publication number: 20090156507
    Abstract: The present invention provides inhibitors of protein kinases comprising a molecule having at least a first moiety competent for penetration of the molecule into cells, and a second moiety for having a protein kinase inhibiting effect within the cells. The first moiety is joined to the second moiety through a linker or a spacer. The complex molecules are preferably peptide conjugates having improved cell-permeability, serum stability and kinase selectivity compared to known protein kinase inhibitors. Pharmaceutical compositions that include these protein kinase inhibitors, and methods of using such compositions for treatment of cancers and other diseases associated with protein kinase activity are also disclosed.
    Type: Application
    Filed: August 22, 2008

  • Patent number: 7407939
    Abstract: The present invention provides small molecules having high affinity to the ATP binding site of protein kinases, which are conjugated to apeptide or peptidomimetic moiety which mimics the substrate of PKB. The chimeric compounds according to the present invention preferably serve as PKB inhibitors with improved activity and selectivity. Novel ATP mimetic compounds, particularly isoquinoline derivatives, conjugated with peptides or peptidomimetics are useful as inhibitors of protein kinases for experimental, medical, and drug design purposes. Furthermore, pharmaceutical compositions comprising these protein kinase inhibitors, and methods of using such compositions for treatment and diagnosis of cancers, diabetes, cardiovascular pathologies, hemorrhagic shock, obesity, inflammatory diseases, diseases of the central nervous system, and autoimmune disease, are disclosed.
