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.

Versatile Synthons for Optically Pure α-Amino Aldehydes and α-Amino Acids: (+)- and (−)-4,5-Dialkoxy-2-oxazolidinones

, 2016
Both enantiomers of trans-5-benzyloxy-4-methoxy- (BMOx) and trans-4,5-dimethoxy-2-oxazolidinones (DMOx), which are readily accessible from simple 2-oxazolone heterocycles, represent good candidates for a new class of chiral synthons for use in the ...

Oxazolidinone polycyclitols. Stereospecific synthesis of novel aminocarbasugars with oxazolidinone ring

Tetrahedron, 2012
Abstract Two new oxazolidinone polycyclitols, 4,5,7,8,9-pentahydroxy-3-tosyldecahydronaphtho [2,1-d]oxazol-2(9bH)-one and 4,5,6,7,8-pentahydroxy-3-tosyldecahydronaphtho [2,1-d]oxazol-2(9bH)-one were synthesized starting from p-benzoquinone. An endo selective Diels–Alder cycloaddition between p-benzoquinone and 1-acetoxybutadiene followed by ...

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.

Chiral (Stereoselective) Drugs, Asymmetric Synthesis, and Racemic Resolution Methods

Chirality, Volume 38, Issue 7, July 2026.
Chirality is crucial in drug development since both biological targets in the organism and the majority of pharmaceutical compounds are chiral. The synthesis and resolution of chiral compounds are critical steps while developing chiral drugs. Asymmetric synthesis and racemic resolution are the two most common methods for obtaining enantiopure drugs ...

Metabolism‐Based Biomarkers for Rapid Phenotypic Antibiotic Susceptibility Testing

Advanced Science, Volume 13, Issue 33, 15 June 2026.
Metabolic differences emerging after antibiotic exposure provide rapid phenotypic signals of susceptibility and resistance. This review summarizes metabolic biomarkers for rapid phenotypic AST, associated with nutrient uptake, respiratory activity, metabolic reprogramming, and enzymatic function. ABSTRACT The accelerating global crisis of antimicrobial
