Discovery of two non-UDP-mimic inhibitors of O-GlcNAc transferase by screening a DNA-encoded library
Bioorg Chem. 2024 Mar 29;147:107321. doi: 10.1016/j.bioorg.2024.107321. Online ahead of print.ABSTRACTFinding potent inhibitors of O-GlcNAc transferase (OGT) has proven to be a challenge, especially because the diversity of published inhibitors is low. The large majority of available OGT inhibitors are uridine-based or uridine-like compounds that mimic the main interactions of glycosyl donor UDP-GlcNAc with the enzyme. Until recently, screening of DNA-encoded libraries for discovering hits against protein targets was dedicated to a few laboratories around the world, but has become accessible to wider public with the recent...

d-type peptides based fluorescent probes for "turn on" sensing of heparin
In this study, seven TPE-1 derived fluorescent probes were rationally designed, efficiently synthesized and evaluated. The stability and water solubility were systematically estimated. Especially, to achieve real-time monitoring of proteolytic stability, the novel Abz/Dnp-based "turn on" probes that employ the internally quenched fluorescent (IQF) mechanism were designed and synthesized. Moreover, the detection ability of synthetic fluorescent probes for heparin were systematically evaluated. Importantly, the performance of d-type peptide fluorescent probe XH-6 indicated that d-type amino acid substitutions could significa...

Discovery of PXR agonists from Hypericum japonicum: A class of novel nonaromatic acylphloroglucinol-terpenoid adducts
Bioorg Chem. 2024 Apr 8;147:107354. doi: 10.1016/j.bioorg.2024.107354. Online ahead of print.ABSTRACTPregnane X receptor (PXR) has been considered as a promising therapeutic target for cholestasis due to its crucial regulation in bile acid biosynthesis and metabolism. To search promising natural PXR agonists, the PXR agonistic activities of five traditional Chinese medicines (TCMs) with hepatoprotective efficacy were assayed, and Hypericum japonicum as the most active one was selected for subsequent phytochemical investigation, which led to the isolation of eight nonaromatic acylphloroglucinol-terpenoid adducts including s...
