  • Patent number: 10815276
    Abstract: Disclosed herein are compounds having activity as cell penetrating peptides. In some examples, the compounds can comprise a cell penetrating peptide moiety and a cargo moiety. The cargo moiety can comprise one or more detectable moieties, one or more therapeutic moieties, one or more targeting moieties, or any combination thereof. In some examples, the cell penetrating peptide moiety is cyclic. In some examples, the cell penetrating peptide moiety and cargo moiety together are cyclic. In some examples, the cell penetrating peptide moiety is cyclic and the cargo moiety is appended to the cyclic cell penetrating peptide moiety structure. In some examples, the cargo moiety is cyclic and the cell penetrating peptide moiety is cyclic, and together they form a fused bicyclic system.

  • Publication number: 20190282654
    Abstract: Disclosed is a general, reversible bicyclization strategy to increase both the proteolytic stability and cell permeability of peptidyl drugs. A peptide drug is fused with a short cell-penetrating motif and converted into a conformationally constrained bicyclic structure through the formation of a pair of disulfide bonds. The resulting bicyclic peptide has greatly enhanced proteolytic stability as well as cell-permeability. Once inside the cell, the disulfide bonds are reduced to produce a linear, biologically active peptide. This strategy was applied to generate a cell-permeable bicyclic peptidyl inhibitor against the NEMO-IKK interaction.
