Click'n ROPISA: One-Pot Synthesis of Ultrabright Fluorescent Nanoparticles Made of Polypeptides. [PDF]

Angew Chem Int Ed Engl
Self‐assembly and fluorophore conjugation proceed rapidly in a one‐pot “Click'n ROPISA” process, yielding intensely fluorescent polypeptide nanoparticles with tunable visible emission. High dye loading enables efficient energy transfer and single‐particle visualization, while the straightforward synthesis provides versatile access to bright ...

CuAAC click chemistry for the enhanced detection of novel alkyne-based natural product toxins [PDF]

, 2018
In the context of discovering and quantifying terminal alkyne-based natural products, here we report the combination of CuAAC click chemistry with LC-MS for the detection of polyether toxins (prymnesins) associated with harmful algal blooms.

Chemical Inhibition of Pyocyanin Biosynthesis Attenuates Virulence of Pseudomonas aeruginosa

Angewandte Chemie, EarlyView.
Anti‐virulence strategies disarm pathogens rather than killing them directly. A β‐lactone reduces pyocyanin production without affecting growth. Chemical proteomics identified PqsC as the primary target via binding to Cys129. Crystallography revealed the binding mode, and SAR yielded a chloroacetamide inhibitor with improved enzymatic potency and anti ...

Active Metal Template Synthesis of Rotaxanes From BINOL‐Phosphate Macrocycles

Angewandte Chemie, EarlyView.
The use of macrocyclic BINOL‐phosphates allows for the active metal template synthesis of [2]rotaxanes via Cu(I)‐mediated alkyne‐azide cycloaddition. DFT calculations, control experiments, and kinetic experiments support a dinuclear phosphate‐Cu2 intermediate.
