In this work we explore the use of microparticulate porous zirconia coated with cellulose tris(3,5-dimethylphenyl-carbamate) (CDMPC) as a support for separation of chiral compounds by HPLC. The surface of zirconia, previously sintered but not rehydroxylated, provides a stable surface for

Compound 1, a cryptand-derived macropentacycle, is a flexible molecule that encompasses many conformations (symmetrical, unsymmetrical, and chiral ones) depending on the observation temperature (VT 1H NMR). Selective monoprotonation of this molecule leads to a totally unsymmetrical, rigidly chiral species in

Several racemic acidic compounds of pharmaceutical and environmental interest have been separated into their enantiomers by nano-liquid chromatography (nano-LC) employing a tert-butylbenzoylated tartardiamide chiral stationary phase (CHI-TBB). CHI-TBB was packed into a fused silica capillary of 100 microm id and

Copper amine oxidases utilize 2,4,5-trihydroxyphenylalanine quinone (topaquinone) as a cofactor in enzymatic catalysis. This cofactor is formed from a tyrosine residue through a self-catalytic mechanism with the participation of the copper ion at the active site. Although pathways have been

The 100-fold increase in toxicity of intraperitoneal (i.p.) rather than orally administered 2-t-butyl-4-methoxyphenol (BHA) is adduced to the depressive effect which this compound exerts on the contractility of the gut musculature. A structure/activity relation study shows the t-butyl group on
