Abstract: The present invention provides peptidomimetic macrocycles capable of modulating growth hormone levels and methods of using such macrocycles for the treatment of disease.

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.

Abstract: The present invention provides novel peptidomimetic macrocycles and methods for their preparation and use, as well as amino acid analogs and macrocycle-forming linkers, and kits useful in their production. Macrocycles of the invention include triazole moieties that crosslink amino acid side chains. The cross links can stabilize a secondary structure of a peptidomimetic macrocycle, such as an ?-helix.

Abstract: The present invention provides biologically active peptidomimetic macrocycles with improved properties relative to their corresponding polypeptides. The invention additionally provides methods of preparing and using such macrocycles, for example in therapeutic applications.
