Abstract: Engineered ionophores capable of increased metal ion transport across hydrophobic membranes and/or reduced metal ion binding affinity, pharmaceutical compositions thereof, kits thereof, ion-selective membrane devices thereof, and methods of use thereof. Hydrophobic membranes can be biological, e.g., cell membranes, or nonbiological, e.g., ion-selective membranes. Engineered ionophores can comprise a metal ion chelator group comprising: a polar binding site having binding atoms to form a metal ion chelate complex; and one or more shielding group(s) in proximity to the binding atoms. Shielding groups can increase the hydrophobic membrane permeability and reduce the binding affinity of the chelate complex. Methods of use can comprise contacting said membranes with said engineered ionophores, metal ion chelate complexes thereof, pharmaceutical compositions thereof, the components of kits thereof, or the like, or any combination thereof.

Abstract: The present disclosure relates to bifunctional chemical conjugation molecules, which find utility as modifiers of target substrates. The present disclosure includes multifunctional compounds comprising an enzyme binding moiety, a chemical linker moiety, and a target binding moiety, which may further include an electrophilic reactive group. Molecules according to the present invention find use making substrate modifications such as post-translational modifications to proteins that are not the natural substrate of the enzyme. Diseases or disorders may be treated or prevented with molecules of the present disclosure.

Abstract: Aspects of the disclosure relate to compositions and methods for targeted protein degradation. In some embodiments, the disclosure relates to methods of evolving protein degrons to interact with certain small molecule inducers (e.g., VS-777, PT-179, or PK-1016). In some embodiments, the disclosure relates to compositions (e.g., peptides, nucleic acids encoding the protein degrons, etc.) used for targeted protein degradation. In some embodiments, the disclosure relates to methods of degrading a target polypeptide in a cell.

Abstract: This invention is related to molecules and methods of use of said molecules or compounds comprising said molecules. A molecule may be a pomalidomide or a thalidomide analogue. A method of inducing degradation of a target protein comprising one or more zinc finger polypeptides in a cell may comprise exposing a cell transfected with the target protein with a molecule as described herein, a pharmaceutically acceptable salt thereof, or any combination thereof. A method of inducing degradation of a target protein comprising one or more FK506 binding protein (FKBP) domains or degradation of a target amine in a cell may comprise exposing a cell transfected with the target protein or comprising the target amine with a composition comprising a molecule as described herein, a pharmaceutically acceptable salt thereof, or any combination of compositions comprising molecules as described herein and pharmaceutically acceptable salts thereof. A method may improve on-target effects and reduce off-target effects.
