1‐Azabicyclo[1.1.0]butanes (ABBs) on the Map: Mechanistic Pathways for Catalytic Ring Opening and Functionalizations

Angewandte Chemie, EarlyView.
Catalytic strain‐release ring opening and functionalizations of 1‐azabicyclo[1.1.0]butanes (ABBs) represent a promising strategy for accessing diverse azetidine products. These transformations proceed via polar pathways, radical pathways, and hybrid mechanisms that combine both.

Molecular MRI Reveals Macrophage‐Enriched Peritumoral Immune Remodeling After Incomplete Ablation in Liver Cancer

Advanced Science, EarlyView.
Incomplete microwave ablation (iMWA) induced a spatially organized, macrophage‐rich immunosuppressive tumor microenvironment (TME) in orthotopic VX2 liver tumors. Molecular MRI enhanced with europium‐doped very small superparamagnetic iron oxide nanoparticles (Eu‐VSOP) noninvasively visualized this remodeling, showing preferential nanoparticle ...

An IscS Persulfide Donates the Sulfur for Ribosomal Protein uL16 Thioamidation

Angewandte Chemie, EarlyView.
YcaO‐catalyzed thioamidation of the ribosomal subunit protein uL16 is widespread in Pseudomonadota bacteria. We identify the iron–sulfur cluster cysteine desulfurase IscS as the sulfur donor via an IscS persulfide and observe direct IscS–uL16 interactions.

The Interplay Between Molybdopterin Synthase and Metal Metabolism Contributes to Pathogenicity in Acinetobacter baumannii

Advanced Science, EarlyView.
Pathogenic Acinetobacter baumannii scavenges metal ions as nutritional elements to survive within the host. This study demonstrates that molybdopterin synthase is essential for pathogenesis and full virulence during infection. Molybdopterin synthase subunit MoaE constitutes an intrinsically disordered C‐terminal histidine rich tail, which mediates ...

S = 3/2 Iron(I)‐Bisphosphine‐Ate Complexes: Synthesis, Characterization, and Reactivity for Electrophile Activation

Angewandte Chemie, EarlyView.
In this work, we present a new class of unusual charged Fe(I)‐bisphosphine‐ates, along with full characterization of their structure and bonding, utilizing low‐temperature synthetic and spectroscopic and techniques. These complexes are highly reactive toward catalytically relevant electrophiles, and can serve as valuable synthons providing access to ...

Synthesis of Deferiprone as a Widely Used Iron-Chelating Drug for the Treatment of Iron-Overload Diseases [PDF]

Trends in Pharmaceutical Sciences
Thalassemia is a genetic disease that significantly affects human health. The common treatment of thalassemia is the regular injection of red blood cell, which is associated with the accumulation of iron in different tissues of the body, and makes ...

Surface‐State‐Driven Selectivity of Electrocatalytic Glucose Oxidation: Metallic Au, Au─OH, and CuO

Advanced Science, EarlyView.
In the electrochemical oxidation of glucose, whether the pyranose ring opens upon adsorption decides the reaction pathway: ring opening on metallic Au yields gluconic acid, gluconolactone formation on Au─OH leads to glucaric acid, and C─C cleavage on CuO gives formic acid. Surface state thus governs product selectivity.

Photoreversible metal chelating agents. [PDF]

, 2018
The main objective of this work has been to design and synthesise new photoreversible metal chelating agents. The reversibility is effected mainly by using light as a switch to isomerise two forms of a chelating agent, (1↔2), where R2 is a metal ...
