Thermally Activated Stereoinversion in Benzotrithiophene‐Based Supramolecular Polymers with Water as the Effector

Angewandte Chemie, EarlyView.
The chiral benzotrithiophene derivative 1 self‐assembles into helical supramolecular polymers whose helicity changes with water content. High water content induces a reversible double stereomutation, while low water content yields a single, stable one. Computational studies show two monomer conformations leading to opposite helices.

Exploring a New Family of (Phosphinochalcogenoyl)Europocenes for Magneto‐Optical Thermometry

Angewandte Chemie, EarlyView.
A new class of substituted cyclopentadienyl ligand featuring a coordinating phosphinothioyl, ‐selenoyl, or ‐telluroyl pendant arm in addition to the typical η5‐mode is presented. The homoleptic divalent europocenes obtained from these are the first examples of organometallic probes for magnetic circular dichroism thermometry at cryogenic temperatures ...

Enantioselective analysis of omeprazole in pharmaceutical formulations by chiral high-performance liquid chromatography and capillary electrophoresis

Journal of the Brazilian Chemical Society, 2004
We developed two sensitive and simple assay procedures based on high- performance liquid chromatography and capillary electrophoresis (CE) for the enantioselective analysis of omeprazole in pharmaceutical formulations.

Properties of epoxide hydrolase from the yeast Rhodotorula glutinis [PDF]

Epoxide hydrolases are ubiquitous enzymes that can be found in nearly all living organisms. Some of the enzymes play an important role in detoxifying xenobiotic and metabolic compounds.
