Opis ogólny

Astec® CHIRALDEX G-TA is the first choice in the Group 1 CSPs (Surface Interactions, Complex Derivatives). This phase has been shown to be the most broadly-selective phase for the pharmaceutical industry, especially for the analysis of chiral intermediates and drug studies in various stages of clinical trials. Separations occur without the inclusion mechanism and are typically faster and more efficient than most chiral stationary phases. G-TA has also been used to separate parent drug enantiomers and their metabolites. G-TA has its highest selectivity for oxygen-containing analytes like alcohols, diols and polyols as the free alcohol and as an acyl derivative; amines as acyl derivatives; amino alcohols, halogens (Cl>Br>F), amino acids, hydroxy acids, lactones, furans and pyrans. It is also highly selective for halogenated compounds.

Zastosowanie

Astec® CHIRALDEX G-TA (2,6-di-O-pentyl-3-trifluoroacetyl-γ-cyclodextrin) derivatized cyclodextrin chiral stationary phase may be used in capillary gas chromatography for separation of four isomers from 7 racemic sulfinate esters. It was used in an experimental study done for cloning and characterization of three epoxide hydrolases identified by analyzing open reading frames (ORFs) of a marine bacterium, Erythrobacter litoralis HTCC2594. It was also used in HPLC and GC analyses of the conversion of epoxides during enantioselectivity of epoxide hydrolase from Agrobacterium radiobacter (EchA) using error-prone PCR and DNA shuffling.

Previously, we reported that ten strains belonging to Erythrobacter showed epoxide hydrolase (EHase) activities toward various epoxide substrates. Three genes encoding putative EHases were identified by analyzing open reading frames of Erythrobacter litoralis HTCC2594. Despite low similarities to reported EHases

The enantioselectivity of epoxide hydrolase from Agrobacterium radiobacter (EchA) was improved using error-prone PCR and DNA shuffling. An agar plate assay was used to screen the mutant libraries for activity. Screening for improved enantioselectivity was subsequently done by spectrophotometric progress

Amino acids are building blocks of peptides and proteins. Enantiomeric separation of these molecules can be performed through chromatography by chiral stationary phases. This article describes the chiral GC analysis of one amino acid, proline, after achiral derivatization.

In this study we demonstrate the separation of D- and L-carvone enantiomers in samples of caraway seed, dill seed, native spearmint and scotch spearmint essential oils using an Astec CHIRALDEX G-TA capillary GC column.
