Synthesis, Characterization and Chemistry of Tetrakis(Propargylisocyanide) Copper(I) Complex
The kinetically unstable propargylisocyanide was reacted with the tetrakis(acetonitrile) copper(I) hexafluorophosphate and the formed complex was then involved in a copper-catalyzed alkyne-azide cycloaddition reaction (CuAAC). After the decomplexation of

Optimizing Benefits‐Harms of H. pylori Screen‐and‐Treat Programs Tailored to the Regional Settings
ABSTRACT This article outlines how decision modeling can be used to optimize the cost‐effectiveness of H. pylori screen‐and‐treat programs. Decision models enable the translation of data from pilot studies into locally tailored strategies by adapting test modalities, treatment options, and the need to retest specific to the local setting.

Direct‐to‐Biology: Streamlining the Path From Chemistry to Biology in Drug Discovery
Crude yet clever: Direct‐to‐biology workflows exploit nanoscale synthesis and plate‐based assays to accelerate hit discovery, save precious intermediates, and rethink early drug discovery. Direct‐to‐biology (D2B) has emerged as a transformative concept in early drug discovery, defined by the direct on‐target screening of crude reaction mixtures without

Synthesis of Oligo‐Sulfonimidates by Exponential Growth via Sulfur‐Phenolate Exchange Reactions
A highly flexible iterative exponential growth strategy is used in combination with the sulfur‐phenolate exchange reaction to develop sequence‐defined oligosulfonimidates (16 mer). Combining this with sulfur‐fluorine exchange‐based iterative step growth, a bespoke 20 mer (Mw = 8.5 kDa) can be synthesized.
