DNA-Compatible Cyclizations
The recent publication in the journal Organic Letters, ‘DNA-Compatible Cyclization Reaction to Access 1,3,4-Oxadiazoles & 1,2,4-Triazoles‘ by our WuXi Biology DEL team, introduces two novel DNA-compatible reactions, successfully incorporating bioactive cores 1,3,4-oxadiazoles and 1,2,4-triazoles into the DEL library. These cores are reported to show broad ranges of biological activities, such as antiviral, anti-inflammatory, anticancer, antifungal, …Read More >
STX-478, a Mutant-Selective, Allosteric PI3Kα Inhibitor Spares Metabolic Dysfunction and Improves Therapeutic Response in PI3Kα-Mutant Xenografts
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 >
How to Accelerate the Synthesis of PROTACs: Strategies and Case Studies
Introduction: Targeted Protein Degradation (TPD) has emerged as a promising therapeutic modality due to its potential to develop therapeutics for previously undruggable targets and address the resistance issues of small molecule inhibitors. Central to this strategy is the novel protein-degradation approach represented by proteolysis-targeting-chimeras (PROTACs), which induce targeted protein degradation through the ubiquitin-proteasome system (UPS). …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 >
Emerging Drug Discovery Strategies for Targeted Protein Degradation
In the last decade, targeted protein degradation (TPD) technology has become one of the most promising methods to remove specific disease-related proteins using cellular self-destruction mechanisms. In our latest White Paper, “Emerging Drug Discovery Strategies for Targeted Protein Degradation” we explore how DNA-encoded library (DEL) technology can be used for direct discovery of proteolysis-targeting chimeras …Read More >
