Total Synthesis of Sacrolide A and Cytotoxic Evaluation

European Journal of Organic Chemistry, EarlyView.
Isolated from the edible cyanobacterium Aphanothece sacrum, sacrolide A is a highly potent antimicrobial and cytotoxic metabolite. Its total synthesis via a convergent strategy enabled accurate assessment of its effects on liver and colon cells, offering new insights into its bioactivity and potential health risks.

Metal‐Free Ligand‐Centered Radical Scavenging in Pyridine‐Modified Tetraaza Macrocycles

European Journal of Organic Chemistry, EarlyView.
Ligand‐centered hydrogen‐atom transfer in pyridinophane macrocycles generates delocalized radicals, with Py2N2 enabling cooperative captodative stabilization and enhanced DPPH• quenching. Pyridine‐modified tetraaza macrocycles are widely studied as ligand platforms for metal coordination, yet their intrinsic redox and radical reactivity in the absence ...

Cyclodextrins as Chiral Selectors in Capillary Electrophoresis—Recent Developments in Understanding Analyte Complexation and Applications in Pharmaceutical Analysis

ELECTROPHORESIS, EarlyView.
Cyclodextrins are the most often applied chiral selectors in CE enantioseparations. In combination with NMR spectroscopy and molecular modeling, studies for an understanding of chiral recognition underlying enantioseparations have been performed.

Protein‐Based High‐Performance Liquid Chromatography and Cyclodextrin‐Capillary Electrokinetic Chromatography for the Chiral Separation of Azoles

ELECTROPHORESIS, EarlyView.
Human serum albumin‐based high‐performance liquid chromatography and cyclodextrin‐based capillary electrokinetic chromatography were used for the chiral separation of azoles. Although only two of the five tested azoles could be enantioseparated by liquid chromatography, all of them were separated by capillary electrokinetic chromatography using single ...

Defective CeO2/Copper Phthalocyanine S‐Scheme Heterojunctions With Molecular Copper Centers for Selective CO2‐To‐CO Photoconversion

Electron, EarlyView.
Defective CeO2/CuPc S‐scheme heterojunction featuring oxygen‐vacancy‐rich ceria nanorods and atomically dispersed Cu–N4 molecular centers. Built‐in electric field mediates efficient S‐scheme charge separation, accumulating strongly reductive electrons at copper sites for selective CO2‐to‐CO photoconversion (92.2% selectivity) via *COOH stabilization ...
