  • Publication number: 20230119612
    Abstract: Provided herein are peptidomimetic macrocycles containing amino acid sequences with at least two modified amino acids that form an intramolecular cross-link that can help to stabilize a secondary structure of the amino acid sequence. Suitable sequences for stabilization include those with homology to the p53 protein. These sequences can bind to the MDM2 and/or MDMX proteins. Also provided herein are methods of using such macrocycles for the treatment of diseases and disorders, such as cancers or other disorders characterized by a low level or low activity of a p53 protein or high level of activity of a MDM2 and/or MDMX protein.

  • Publication number: 20230086093
    Abstract: The present invention provides a mutant RSV F protein having a mutation, wherein the mutation is a substitution of a leucine corresponding to a leucine at position 141 of an amino acid sequence of SEQ ID NO: 1 or a leucine corresponding to a leucine at position 142 with a cysteine, and a substitution of a leucine corresponding to a leucine at position 373 with a cysteine, and a disulfide bond is formed between the cysteines. Further provided is a mutant RSV F protein having a mutation, wherein the mutation is a substitution of a glutamic acid corresponding to a glutamic acid at position 60 of the amino acid sequence of SEQ ID NO: 1 with a non-acidic amino acid.

  • Publication number: 20180340009
    Abstract: The disclosed peptidomimetic macrocycles modulate the activity of MCL-1. Myeloid cell leukemia 1 (MCL-1) is a protein that inhibits cell death. Peptidomimetic macrocycles, pharmaceutical compositions, and methods disclosed herein can be used for the treatment of disease in which MCL-1 is over-expressed, such as cancer. In particular, MCL-1-modulating peptidomimetic macrocycles disclosed herein can be applied in the setting of resistance to BCL-2 family inhibitors, which is often engendered by MCL-1 over-expression or hyper-activation.
