ABSTRACT Flavobacterium psychrophilum and Flavobacterium branchiophilum are important fish pathogens that cause considerable economic losses in freshwater aquaculture worldwide. Their antimicrobial resistance (AMR) profiles were evaluated using the latest Clinical and Laboratory Standards Institute broth microdilution method, which was adjusted for F ...

Pallado-Catalyzed Cascade Synthesis of 2-Alkoxyquinolines from 1,3-Butadiynamides
A novel synthesis strategy to access 2-alkoxyquinoline derivatives via a palladium-driven cascade reaction is disclosed. Unlike classic methods based on the alkylation of 2-quinolones with alkyl halides, the present method benefits from the de novo ...

The study explores a photocatalytic reaction to activate an intramolecular [2 + 2] cycloaddition of a 3‐(but‐3‐enyl)oxyquinolone substrate using a chiral xanthone catalyst. Computational analysis of two substrate‐catalyst encounter complexes reveals different rates for energy transfer due to orbital overlap.

Designing Enzymatic Reactivity with an Expanded Palette
Innovation in biocatalysis is rapidly increasingly the diversity of catalytic reactivity that can be mediated by enzymes, addressing a key bottleneck for their widespread adoption in industrial chemical synthesis. A key approach to this is building enzymes with unnatural catalytic components that provide an expanded palette with new possibilities for ...
