Inhibition of the Werner syndrome RecQ helicase (WRN) is a promising approach for the treatment of cancers commonly associated with microsatellite instability. To support drug discovery programs, we have established off-the-shelf crystallization systems to enable the determination of high-resolution X-ray crystal structures with a short turnaround time. Together with our protein production service and off-the-shelf …Read More >

STAT proteins are key mediators of cellular immunity, proliferation, apoptosis, and differentiation.  STATs are known to play a role in the pathogenesis of many different diseases (including cancer) and the development of drugs directly or indirectly targeting STAT signaling has become a major focus for discovery teams.  WuXi AppTec offers a comprehensive platform of biophysical …Read More >

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 >

RecQ helicases (BLM, WRN, RECQL, RECQL4, and RECQL5) are an important family of surveillance proteins that play critical roles in genome maintenance and stability. Inherited mutations in these helicases are linked to distinct human disease syndromes, as well as cancer. To support the discovery of potent and selective RecQ helicase inhibitors, WuXi AppTec offers a …Read More >

Cyclin-dependent kinases (CDKs) and their cyclin regulatory subunits form complexes that are essential for driving abnormal growth processes in cancer cells, making these molecules important targets for cancer treatment. To support the discovery of novel CDK inhibitors, WuXi AppTec offers a comprehensive platform of biophysical and biochemical assays to accelerate hit finding and lead optimization …Read More >

WuXi AppTec provides a comprehensive platform of advanced biophysical assays and structural biology services to accelerate lead optimization efforts focused on GPCRs and membrane proteins.

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 >

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 >

Within the PI3K family, the heterodimer comprising the p110-α catalytic and p85-α regulatory subunits (encoded by PIK3CA and PIK3R1) is essential in the regulation of cellular proliferation and carcinogenesis.  To support the discovery of novel PI3K inhibitors, WuXi AppTec offers an integrated platform of ready-to-go assays and Spectral Shift technology within Dianthus, an affinity screening …Read More >
