Preparation and characterization of poly(l-phenylalanine) chiral stationary phases with varying peptide length.

Review High-performance liquid chromatographic enantioseparation of drugs containing multiple chiral centers on chiral stationary phases

In recent years there has been considerable interest in the synthesis and separation of enantiomers of organic compounds especially because of their importance in the biochemistry and pharmaceutical industry. High-performance liquid Chromatography is a very useful method for the direct separation of enantiomers. However, about 30−40 years ago, commercially available chiral stationary phases wer...

Focusing Review Development and Pharmaceutical Applications of Functional Stationary Phases for Capillary Electrochromatography and Chiral Separation

We synthesized 3-(4-sulfo-1,8-naphthalimido)propyl-modified silica (SNAIP) for capillary electrochromatography (CEC). The unique structure of SNAIP contributed to the retention by three interactions including hydrophobic, electrostatic and interactions and the acceleration of electroosmotic flow at an acidic condition. The CEC employing SNAIP was successively applied to the rapid separations of...

Metabolomics-Based Study of Logarithmic and Stationary Phases of Promastigotes in Leishmania major by 1H NMR Spectroscopy

Background: Cutaneous leishmaniasis is one of the most important parasitic diseases in humans. In this disease, one of the responsible organisms is Leishmania major, which is transmitted by sandfly vector. There are specific differences in biochemical profiles and metabolite pathways in logarithmic and stationary phases of Leishmania parasites. In the present study, 1H NMR spectroscopy was used...
