Discovery of a Phenylalanine‐Derived Natural Compound as a Potential Dual Inhibitor of MDM2 and MDMX
ChemMedChem, EarlyView.P5, a novel phenylalanine‐derived compound isolated from Micromonospora sp. MS‐62, exhibits dual inhibition of MDM2 and MDMX. Molecular docking and SPR confirm its nanomolar affinity and sustained binding kinetics. In silico profiling reveals high GI absorption, BBB permeability, and drug‐likeness, highlighting its potential as a lead for p53‐targeted ...

iMeta, EarlyView.This study demonstrates that hypoacylated, rough‐type lipopolysaccharides (LPS) derived from Akkermansia muciniphila strain HW07 (ALPS) alleviates diet‐induced obesity. ALPS acts as a weak TLR4 agonist and significantly reduces weight gain, improves metabolic parameters, and restores gut barrier integrity in obese mice.
