Summary of "High-performance liquid chromatographic and subcritical fluid chromatographic separation of α-arylated ß-carboline, N-alkylated tetrahydroisoquinolines and their bioisosteres on polysaccharide-based chiral stationary phases."

New, pharmacologically interesting chiral amino compounds, namely stereoisomers of α-hydroxynaphthyl-ß-carboline, benz[d]azepine and benz[c]azepine analogs as well as N-α-hydroxynaphthylbenzyl-substituted isoquinolines were enantioseparated by high-performance liquid chromatographic and subcritical fluid chromatographic (SFC) methods on polysaccharide-based chiral stationary phases. Separation of the stereoisomers was optimized in both SFC and normal phase liquid chromatographic (NP-LC) modalities by investigating the effects of the composition of the bulk solvent, temperature, and the structures of the analytes and selectors. Both NP-LC and SFC exhibited satisfactory performance, albeit with somewhat different effectiveness in the separation of the stereoisomers studied. The optimized methods offer the possibility to apply preparative-scale separations thereby enabling further pharmacological investigations of the enantiomers. This article is protected by copyright.

Medical and Biotech [MESH] Definitions

Liquid chromatographic techniques which feature high inlet pressures, high sensitivity, and high speed.

Chromatographic techniques in which the mobile phase is a liquid.

A hybrid separation technique combining both chromatographic and electrophoretic separation principles. While the method was invented to separate neutral species, it can also be applied to charged molecules such as small peptides.

A chromatographic technique that utilizes the ability of biological molecules to bind to certain ligands specifically and reversibly. It is used in protein biochemistry. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)

A method of separation of two or more substances by repeated distribution between two immiscible liquid phases that move past each other in opposite directions. It is a form of liquid-liquid chromatography. (Stedman, 25th ed)
