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 >

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 >

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 >

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 >

SITC Poster #466: Mutant KRAS is linked to PD-L1 expression, and oncogenic RAS signaling promotes an immunosuppressive tumor microenvironment by upregulating PD-L1 expression. Consequently, combining KRAS G12C inhibitors with immune checkpoint blockers shows promising benefits. To better understand the mechanisms underlying the combined inhibition of KRAS G12C inhibitor AMG 510, and anti-PD-1 antibody nivolumab, LU-01-0361 …Read More >

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 >

The KRAS G12D mutation subtype is present in over 40% of pancreatic ductal adenocarcinomas (PDAC), making this an important drug target.  WuXi AppTec scientists recently contributed to a research article in ACS Med. Chem. Letters describing the optimization of a series of potent and selective KRAS G12D inhibitors through a structure-based drug design approach.  The …Read More >

The metabotropic glutamate receptor mGluR7 is widely expressed throughout the CNS and has been implicated in numerous CNS disorders.  WuXi AppTec scientists recently contributed to a study which led to the identification, optimization, and characterization of a highly potent, novel mGluR7 allosteric agonist, designated CVN636.  The authors show that CVN636 has high selectivity toward mGluR7, …Read More >

Introduction: WuXi AppTec scientists recently contributed to a study which led to the discovery and optimization of a novel series of GST inhibitors. The authors used affinity mediated DNA-encoded library selection against a privileged scaffold to identify a compound with potent inhibition against human glutathione S-transferase Mu 2.  SAR studies, coupled with X-ray crystallography and …Read More >
