The contribution of the X-ray crystallography team from our WuXi AppTec site in Germany was acknowledged in a recent study published in the journal Cancer Discovery. In this study, the authors show that compound STX-478, an allosteric PI3Kα inhibitor, selectively targets prevalent PI3Kα helical- and kinase-domain mutant tumors. STX-478 demonstrated robust efficacy in human tumor …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 >
