Regenerable Surface Plasmon Resonance (SPR) Surfaces for Reliable, Cost-Effective, and Wide-Ranging Applications
Traditional SPR-based drug discovery efforts in the small-molecule space have revolved around single-use chips for screening and hit-to-lead efforts. Inspired by recent technological advances, we have established simple regenerable protocols that can (1) accommodate target-proteins with common tags such as His- and Avi-, (2) reach sufficient surface density for small-molecule testing, and (3) maintain a …Read More >
DNA-Encoded Macrocyclic Peptide Libraries Enable the Discovery of a Neutral MDM2–p53 Inhibitor
Macrocyclic peptides are an emerging molecular class for targeting intracellular protein–protein interactions (PPIs) and for providing an oral modality for drug targets. Herein, we use DNA-encoded cyclic peptide libraries to discover a neutral nonapeptide, UNP-6457, that inhibits MDM2–p53 interaction with an IC50 of 8.9 nM. These studies showcase how tailored DEL libraries can directly yield …Read More >
Discovery of RNA Targeting Small Molecules – Our Toolbox for RNA Drug Discovery
Drug Discovery Chemistry Conference 2023 WuXi AppTec has developed technologies to facilitate RNA small molecule screening, an exciting frontier in drug discovery. SHAPE-MaP is applied to determine RNA structure and dynamics and verify small molecule binding. We utilize the “DNA-Zipper” strategy to enable DNA-encoded libraries to identify RNA binders. With other technologies including fragment-based drug …Read More >
