Despite the success of delivery technologies such as lipid nanoparticles and trivalent GalNAc conjugation, targeted delivery of oligonucleotides to extra hepatic tissues remains a challenge.  At this year’s OPT Congress, WuXi AppTec presented a poster showing the utilization of our peptide-based DNA-encoded library screening platform to identify endocytosis receptor-binding peptides.  The binding affinity of hit …Read More >

WuXi AppTec scientists contributed to a research article in the journal Translational Medicine Communications which characterized the antitumor immune responses generated by iMN041, a prodrug of a DNA methyl transferase/ribonucleotide reductase inhibitor.  This study also assessed the efficacy of iMN041 in mouse xenografts of human clear cell renal cell cancer, pancreatic cancer, and triple negative …Read More >

Patient-derived xenografts (PDXs) represent a powerful platform for cancer drug screening and biomarker discovery and are considered the gold standard of in vivo models for their proven clinical relevance to human disease. WuXi AppTec offers a comprehensive platform of more than 1,400 well-annotated PDXs across 30 cancer types. We also provide expanded in vitro, ex …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 >

Review of SITC 2023 Annual Meeting The 38th Annual Meeting of the Society for Immunotherapy of Cancer (SITC) was held this year in San Diego, CA, USA. As one of the most influential international conferences dedicated to cancer immunotherapy, SITC provides attendees with a cross-disciplinary educational and interactive platform. This meeting focuses on discussing and …Read More >

SITC Poster #59: Since the emergence of the COVID-19 pandemic, numerous nucleic-acid therapeutics have been approved for clinical use. Distinguished from conventional protein-targeted therapy, nucleic acid therapeutics offer the potential for sustained effects via gene modification or inhibition. In this study, we conducted a comprehensive evaluation of the activity and anti-tumor effects of PKN3-targeted siRNA …Read More >

SITC Poster #1162: Enhertu is currently approved for the treatment of patients with HER2-positive breast cancer, gastric cancer, or HER2-mutant non-small cell lung cancer. However, despite Enhertu’s clinical benefits, most patients inevitably experience disease progression and mortality. Understanding drug resistance mechanisms can aid in developing new treatment strategies for drug-resistant clinical patients. In this study, …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 >
