  • Publication number: 20220267376
    Abstract: Peptidomimetic macrocycles that comprise all-D configuration ?-amino acids and bind mouse double minute 2 (MDM2 aka E3 ubiquitin-protein ligase) and MDMX (aka MDM4) are described. These all-D configuration ?-amino acid peptidomimetic macrocycles are protease resistant, cell permeable without inducing membrane disruption, and intracellularly activate p53 by binding MDM2 and MDMX thereby antagonizing MDM2 and MDMX binding to p53. These peptidomimetic macrocycles may be useful in anticancer therapies, particularly in combination with chemotherapy or radiation therapy.

  • Patent number: 11319344
    Abstract: The present invention relates to non-membrane disruptive and p53 activating stapled peptides, as well as methods of treatment of cancer involving the use of these peptides. In one embodiment, the peptide comprises or consist of the amino acid sequence of TSFXaa1EY-WXaa3LLXaa2, where Xaa1 is (R)-2-(7?-octenyl)alanine or derivative thereof, or is (R)-2-(4?-pentenyl)alanine or derivative thereof; and Xaa2 and Xaa3 are independently any type of amino acid or modified amino acid. In another embodiment, the peptide comprising or consisting of the amino acid sequence of TSFXaa1EYW Xaa3LLXaa2ENXaa5, wherein Xaa1 and Xaa3 are any type of amino acid or modified amino acid; Xaa2 is S, or P, or (S)-2-(4?-pentenyl)alanine or a derivative of (S)-2-(4?-pentenyl)alanine; and wherein Xaa5 is F or Y.
