Heme Oxygenase-1-Targeting Molecules
WuXi AppTec scientists published a study in the open access archive ChemRxiv describing the discovery of highly selective, novel, heme oxygenase-1 (HO-1) targeting molecules. HO-1, primarily a heme-degrading enzyme, has been identified as a potential therapeutic target in diseases such as cancer and neurodegenerative disorders. Here, we report the discovery of five series of novel …Read More >
Addition of Covalent Warhead and DEL-Generated Hit Fragmentation Empower FBDD
Fragment-based drug discovery (FBDD) is one of the most well-developed approaches for projects starting from small, low-affinity compounds. At the SLAS 2024 meeting in Boston, WuXi AppTec presented a poster reporting on the assembly of a covalent fragment library that is suited to tackle protein targets via serine, lysine, and cysteine residues. In a case …Read More >
DEL Insight: Novel Applications with the Bifunctional Linker of DNA-encoded Molecules
Due to the special configuration of the DNA encoded library (DEL), each DEL molecule carries a DNA sequence encoding its identity through a bifunctional linker. The linkers that are considered “redundant” and “troublesome” in traditional drug discovery actually offer innate advantages in many application scenarios. In this article, we review how to utilize DNA-encoded libraries …Read More >
Covalent Fragment-based Drug Discovery: BTK Inhibitors
At the Covalent Drug Discovery 2023 Summit and Fragments 2024 Conference, we presented a case study on Bruton’s tyrosine kinase (BTK) and demonstrated how biochemical, biophysical, and structural biology methods were used to confirm hits, characterize binding kinetics, and evaluate the mode of interaction of covalent BTK inhibitors. Our hit-to-lead workflow showcases the importance of bioanalytical …Read More >
Biophysical and Structural Biology Methods Enable Fragment-Based Ligand Discovery
Powerful biophysical and structural biology tools enable the study of large numbers of fragments and are opening new possibilities in the treatment of various diseases. In this webinar, WuXi AppTec presents the results of a conventional and covalent fragment-based drug discovery screen, and our expert speaker discusses how orthogonal biophysical and structural methods enable the …Read More >
Negative Allosteric Modulation of the µ-Opioid Receptor
DNA-encoded libraries from WuXi AppTec were used in a “steered” screening against either inactive or active μ-opioid receptors in parallel, to find novel negative allosteric modulators of this receptor. The molecule discovered via DEL screening not only shows direct and effective in vitro and in vivo potency, but also helps elucidate the mechanism of negative allosteric modulation of GPCRs. This discovery …Read More >
Empowering Small Molecule Drug Discovery by Automatic DEL Screening
In this webinar, our expert speakers showcase our automatic DNA-encoded library (DEL) screening device, DELman. DNA-encoded library technology has proven to be a powerful tool for drug discovery. There are now several DEL-derived candidates in clinical stage. DEL enables researchers to explore vast chemical space with millions to billions of compounds. With DELman and other …Read More >
Dianthus Platform: Screening for Modulators of SIK3
Salt-inducible kinases (SIKs) have recently emerged as key regulators of oncogenesis, inflammation, and immune responses, making these enzymes an important drug target. The isoform SIK3 is a novel regulator of tumor-intrinsic resistance to cytotoxic T cell attack. To support the discovery of novel SIK3 modulators, WuXi AppTec offers an integrated platform of ready-to-go biophysical assays …Read More >
Dianthus Platform: Screening for CRBN-DDB1 Proteolysis-Targeting Chimeras and Molecular Glues
Cereblon (CRBN) forms an E3 ligase complex together with DDB1, CUL4, and RBX1. CRBN functions as a substrate receptor of this complex for the recognition and binding of proteins targeted for ubiquitination and proteasomal degradation. To support the discovery of CRBN-DDB1 proteolysis-targeting chimeras and molecular glues, WuXi AppTec offers an integrated platform of ready-to-go assays …Read More >
