Protein lysine crotonylation has emerged as an important post-translational modification (PTM) in the regulation of gene transcription through epigenetic mechanisms. Here we introduce a chemical probe, based on a water-soluble phosphine warhead, which reacts with the crotonyl modification. We show that this reagent is complementary to antibody-based tools allowing detection of endogenous cellular proteins

nybomycin natural products have the potential to extend the clinical efficacy of the marketed fluoroquinolone class of antibiotics through a 'reverse antibiotic' approach. However, only very limited structure-activity relationships are known for these fascinating compounds, in part due to challenges with their synthesis. Here we report a new scalable and robust synthetic route to the nybomycin natural products
