WuXi AppTec scientists recently contributed to a research article in the Royal Society of Chemistry describing the large-scale synthesis of a potent and selective inhibitor of Notum carboxylesterase (an enzyme that suppresses Wnt signaling pathways).  By employing a modified Sakai reaction as the key step, a one-pot synthesis of this Notum inhibitor was developed, enabling …Read More >

KRAS mutant proteins that drive cancer development are highly similar in sequence and structure. Direct inhibitors are most likely to bind to the catalytic domain of KRAS. However, recent studies have found that KRAS mutants can also be targeted by heterogeneous sites, to develop covalent inhibitors of KRAS mutants. The discovery of inhibitors that selectively …Read More >

This webinar will focus on aspects related to PROTAC discovery and chemistry workflows, such as ligand finding strategies, synthesis optimization, and linker design. Successful development of bifunctional molecules requires a deep understanding of multiple processes, including biophysical events which dictate induced proximity and how technologies such as DNA-encoded libraries (DEL) can be leveraged to identify …Read More >

This webinar will focus on PROTAC biology workflows, such as in vitro screening assays, in vivo testing, and optimization of DMPK properties. Topics will include the best use of biochemical assays to measure binary/ternary complex formation, cell-based assays to assess target engagement and degradation, strategies for enhancing drug delivery and formulation, and PK/PD evaluation of …Read More >

https://www.nature.com/articles/s43586-021-00084-5  Abstract DNA-encoded chemical library (DECL) technology is used by the pharmaceutical industry to discover small molecules capable of modulating biologically relevant targets. DECL synthesis starts with an oligonucleotide that contains a chemical linker moiety, and proceeds through iterative cycles of DNA barcode elongation and chemical synthesis. DECL selections require little protein, minimal assay development …Read More >

Fragment-based drug discovery (FBDD) is a method used for finding hit compounds as one strategy of hit identification in the drug discovery process. Fragments are small molecules with a low molecular weight, smaller than lead molecules or druglike molecules. The FBDD technology is based on identifying small chemical fragments, which bind to the biological target …Read More >

Challenging targets, such as membrane proteins or protein-protein interactions were considered undruggable in the past. However, today a variety of screening methods can be used to help develop drugs against these formerly undruggable targets.
