Abstract: The present application describes stapled peptide degron chimeras, which act as protein degradation inducing moieties, either by combining a stapled peptide that binds a disease-related protein with a small molecule degron, such as a cereblon- or VHL-binding small molecule as the degron, or a polypeptide sequence degron, such as a Cop1-binding Trib peptide as the degron; or by combining a stapled peptide degron with a peptide, such as a stapled peptide, or a small molecule that binds a disease-related protein. The present application also relates to methods for the targeted degradation of endogenous proteins through the use of stapled peptide degron chimeras which can be utilized in the treatment of proliferative disorders or other conditions whereby elimination of a disease-causing or disease-related protein would have a therapeutic benefit. The present application also provides methods for making compounds of the application and intermediates thereof.

Abstract: The invention provides structurally-constrained peptides by hydrocarbon stapling of a BCL9 HD2 helix for use as a therapeutic agent. The invention further provides methods and kits for use of the structurally-constrained peptide of the instant invention. The invention is based, at least in part, on the results provided herein demonstrating that hydrocarbon stapled helical peptides display excellent proteolytic, acid, and thermal stability, restore the native helical structure of the peptide, possess superior pharmacokinetic properties compared to the corresponding unmodified peptides, and are highly effective in binding to ?-catenin in vitro, in cellulo, and in vivo, disrupting the BCL-9/?-catenin interaction, and thereby interfering with deregulated Wnt/?-catenin signaling for therapeutic benefit in a variety of human diseases including human cancer.

Abstract: Methods of generating and optimizing stabilized (e.g., stapled and/or stitched) anti-microbial peptides (StAMPs) for the prophylaxis and treatment of antibiotic-resistant (e.g., colistin-resistant, methicillin resistant, meropenem-resistant) bacterial infections (e.g., Gram-negative, Gram-positive), and methods for using such peptides for experimental investigation, livestock management, management of crops/trees/plants, and/or therapeutic benefit. Also featured are methods for reducing renal toxicity of a StAMP.

Abstract: Provided herein are compositions comprising a compound of Formulas I, II, or III, and compositions a compound comprising a moiety of Formula IV, which are useful for sensitizing and/or activating pro-apoptotic activity of BAX.

Abstract: In some embodiments, a mass spectrometry tag may comprise a linker region, a mass balance region, and a reporter region. The mass spectrometry tag may be configured to fragment in a mass spectrometer via an energy dependent process to produce multiple reporter molecules. For example, the reporter region of the tag may be configured to produce at least two reporter molecules via fragmentation. In some embodiments, one or more regions of the tag may comprise at least one heavy isotope. In some such embodiments, the ability to fragment into multiple reporter molecules as well as the placement and/or number of heavy isotope(s) allows the mass spectrometry tag to be distinguished from other similar mass spectrometry tags. In some such embodiments, the ability to distinguish between tags having the same or substantially similar total mass to charge ratio and reporter region mass may allow the system to have a greater multiplexing capacity than conventional systems.

Abstract: The present invention provides stably crosslinked insulinotropic polypeptides having superior and unexpected benefits in the treatment of conditions involving abnormal glucose homeostasis, e.g., type 2 diabetes and conditions relating to type 2 diabetes. Such benefits include, but are not limited to, extended polypeptide half-life, enhanced alpha-helicity, improved thermal stability and protease resistance, increased functional activity and pharmacologic properties, improved bioavailability when administered by any route, and improved bioavailability and gastrointestinal absorption when delivered orally, as compared to the corresponding unmodified polypeptides. The invention also provides compositions for administering the polypeptides of the invention, as well as methods for preparing and evaluating the polypeptides of the invention.
