Enantioseparation of Amino Acids Using a Chiral Recognition Polymer

詳細技術說明: Researchers at UCLA have developed a new chiral recognition polymer that has the following advantages: 1. Direct separation of free amino acids. 2. Usable for both analytical and preparative purposes. 3. Uses aqueous solutions and alcohol; no buffer solutions are needed. 4. Easy scale-up. 5. A large chiral recognition capacity compared to natural biopolymers, such as Human Serum Albumin (HSA) and Bovine Serum Albumin (BSA). 6. Reusable. 7. Can be used as a chiral sensor. 8. Potential for adaptation for pharmaceutical separations.This new polymer strongly interacts with one enantiomeric form of an amino acid or component in a racemic mixture enabling chiral separations. An efficient way of employing the polymer to separate enantiomers of amino acids is by the use of a column containing a high-surface-area of the polymer. Experimental data has shown a separation factor of alpha = 8.4 for dl-phenylalanine using a 250mm column. Since alpha > 2 is considered to be potentially useful commercially, alpha of 8.4 is remarkable.

Background

Enantioseparations are becoming increasingly important because the U.S. Food and Drug Administration has declared if a drug is chiral, the biological effects of both enantiomers must be determined. Many procedures for resolutions of D, L-amino acids have been documented on an analytical scale. The limitations of these methods is generally the economic cost, in addition to the difficulty of being scaled up.
