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 >

Delivery carriers are a critical component in the development of mRNA vaccines. Here, we describe the synthesis of a cationic polymer as a carrier for mRNA cancer vaccine delivery. In vivo results show that this polymer-based mRNA vaccine significantly delays tumor growth after vaccination of mice. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9743697/  

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 >
