Application

Protein degrader builiding block (S,R,S)-AHPC-PEG4-Alkyne enables the synthesis of molecules for targeted protein degradation and PROTAC (proteolysis-targeting chimeras) technology. This conjugate contains a von Hippel-Lindau (VHL)-recruiting ligand and a PEGylated crosslinker with pendant alkyne for click chemistry with an azide on the target ligand. Because even slight alterations in ligands and crosslinkers can affect ternary complex formation between the target, E3 ligase, and PROTAC, many analogs are prepared to screen for optimal target degradation. When used with other protein degrader building blocks with a pendant alkyne group, parallel synthesis can be used to more quickly generate PROTAC libraries that feature variation in crosslinker length, composition, and E3 ligase ligand.

EDC4 is a core component of processing (P)-bodies that binds the DCP2 decapping enzyme and stimulates mRNA decay. EDC4 also interacts with mammalian MARF1, a recently identified endoribonuclease that promotes oogenesis and contains a number of RNA binding domains, including

The current inhibitor-based approach to therapeutics has inherent limitations owing to its occupancy-based model: 1) there is a need to maintain high systemic exposure to ensure sufficient in vivo inhibition, 2) high in vivo concentrations bring potential for off-target side effects, and 3) there is

Conventional genetic approaches have provided a powerful tool in the study of proteins. However, these techniques often preclude selective manipulation of temporal and spatial protein functions, which is crucial for the investigation of dynamic cellular processes. To overcome these limitations

Traditional pharmaceutical drug discovery is almost exclusively focused on directly controlling protein activity to cure diseases. Modulators of protein activity, especially inhibitors, are developed and applied at high concentration to achieve maximal effects. Thereby, reduced bioavailability and off-target effects can
