Publication number: 20230119612Abstract: 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.Type: ApplicationFiled: June 22, 2022Publication date: April 20, 2023Inventors: Vincent GUERLAVAIS, Carl ELKIN, Huw M.

Publication number: 20180340009Abstract: 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.Type: ApplicationFiled: May 17, 2018Publication date: November 29, 2018Inventors: Vincent Guerlavais, Eric Feyfant
