On-bead DEL Application and Case Study for Drug Discovery
DNA-encoded library (DEL) technology has been recognized as a major screening method with unique advantages for offering vast chemical diversity and multiplexed affinity-based screening. Recently, solid-phase On-bead DEL, also known as one bead one compound (OBOC), has been developed to further expand DEL screening from affinity-based screening into biochemical activity screening. At the 2025 SLAS …Read More >
Discovery of a Novel Covalent Inhibitor Using DEL
With advancements in drug design, there is resurging interest in drugs that form covalent bonds with their targets. Covalent drugs have the potential to provide enhanced potency and prolonged duration of action compared to non-covalent drugs. Emerging areas of interest include the development of reversible covalent inhibitors, covalent degraders, and covalent targeting of non-cysteine amino …Read More >

Discovery of a Selective BET Inhibitor for Treating Osteoarthritis
Bromodomain and extra-terminal domain (BET) family proteins are key regulators of gene transcription and have been implicated in a wide range of diseases, making these proteins a potential therapeutic target. Abnormal BET protein activity has been linked to cancer, inflammatory disorders, viral infections, and neurodegenerative conditions. In a recent publication, researchers highlight the discovery of …Read More >
Discovery of GuaB Inhibitors for the Treatment of Tuberculosis
Tuberculosis is the leading cause of death from an infectious disease and is caused by Mycobacterium tuberculosis (MTB). Inosine-5′-monophosphate dehydrogenase (GuaB) is an enzyme that performs the rate-limiting step in the de novo biosynthesis of guanine, which is critical for growth of bacteria, including MTB. The development of a novel antibiotic that inhibits GuaB could …Read More >
Small Molecule Reactivator of p53 Y220C Mutant
Mutant p53 is one of the most attractive targets for new anti-cancer drugs. Although traditionally regarded as difficult to drug, several new strategies have recently become available for targeting the mutant protein. One of the most promising of these involves the use of low molecular weight compounds that promote refolding and reactivation of mutant p53 …Read More >

Pharmacodynamic and Pharmacokinetic Profile of a Novel GLP-1 Receptor Biased Agonist
Glucagon‐like peptide‐1 (GLP-1) receptor agonists have emerged as promising therapeutic options for addressing type‐2 diabetes, obesity, and related conditions. However, because of the continued need for injectable administration, many GLP-1 agonists face compliance challenges. To improve the design and production of GLP-1 receptor biased agonists with enhanced druggability, a novel small molecule, designated SAL0112, was …Read More >
Preclinical Evaluation of the SARS-CoV-2 Mpro Inhibitor RAY1216
WuXi AppTec scientists contributed to a research article in the journal Nature Microbiology, which characterized a peptidomimetic inhibitor of the SARS-CoV-2 main protease (Mpro). In a human ACE2 transgenic mouse model, this inhibitor (designated RAY1216) exhibited antiviral activities against SARS-CoV-2 comparable to those of nirmatrelvir, but with improved pharmacokinetics.
