Abstract
The identification of chiral penicillamine (Pen) is of great significance for clinical medication safety. The host-guest systems formed by enantiomers and macromolecule can be applied to differentiate the chiral drugs and enable the drug delayed release. We hereby performed the dispersion corrected density functional theory (DFT-D) calculation on the complex formed by β-cyclodextrin(β-CD) and D/L-penicillamine (D/L-Pen). The diverse encapsulation configurations with different interaction energy show that both D-Pen and L-Pen tend to longitudinally embedded into the narrow aperture of β-CD with the front part of the sulfur group and the methyl group, and the interaction energy between L-Pen and β-CD is 5.47 kJ/mol(M062XD3) lower than that between D-Pen and β-CD. Based on the computed vibration frequency of host, guest, and the most stable complex, it is found that the featured peaks attributed to the vibration of the carboxyl group of guest and the skeleton vibration of complex are the most significant spectral standard to distinguish the β-CD-D/L-Pen and β-CD. Moreover, the peaks resulted from the skeleton vibration in terahertz spectra can be also used to distinguish the complex of β-CD with chiral Pen. Through the topological analysis and the Independent Gradient Model (IGM) analysis, the O-H…O hydrogen bond in β-CD-D-Pen is stronger than that in β-CD-L-Pen, and the van der Waals interactions such as C-H…O,C-H…N,C-H…S, O…S and C-H…C-H have the most contributions to the intermolecular interaction in β-CD-D/L-Pen. It is also noted that the H(-OH) in D-Pen and S in L-Pen contribute the most to the intermolecular interaction with β-CD in comparison with other atoms in Pen.

Abstract
Gas-phase equilibrium adsorption of D- and L-serine (Ser) mixtures and D- and L-phenylalanine (Phe) mixtures has been studied on the naturally chiral Cu{3,1,17}(R&S) surfaces. (13)C labeling of the l enantiomers (*L-Ser and *L-Phe) has enabled mass spectrometric enantiodiscrimination of the species desorbing from the surface following equilibrium adsorption. On the Cu{3,1,17}(R&S) surfaces, both equilibrium adsorption and the thermal decomposition kinetics of the D and *L enantiomers exhibit diastereomerism. Following exposure of the surfaces to D/*L mixtures, the relative equilibrium coverages of the two enantiomers are equal to their relative partial pressures in the gas phase, θ(D)/θ(*L) = P(D)/P(*L). This implies that adsorption is not measurably enantiospecific. The decomposition kinetics of Ser are enantiospecific whereas those of Phe are not. Comparison of these results with those for aspartic acid, alanine, and lysine suggests that enantiospecific adsorption on the naturally chiral Cu surfaces occurs for those amino acids that have side chains with functional groups that allow strong interactions with the surface. There is no apparent correlation between amino acids that exhibit enantiospecific adsorption and those that exhibit enantiospecific decomposition kinetics.

Abstract
This study proposes a sensitive method for the simultaneous separation and concentration of 9 pairs of amino acid enantiomers by combining poly(ethylene oxide) (PEO)-based stacking, β-cyclodextrin (β-CD)-mediated micellar electrokinetic chromatography (MEKC), and 9-fluoroenylmethyl chloroformate (FMOC) derivatization. The 9 pairs of FMOC-derivatized amino acid enantiomers were baseline separated using a discontinuous system, and the buffer vials contained a solution of 150 mM Tris-borate (TB), 12.5% (v/v) isopropanol (IPA), 0.5% (w/v) PEO, 35 mM sodium taurodeoxycholate (STDC), and 35 mM β-CD, and the capillary was filled with a solution of 1.5 M TB, 12.5% (v/v) IPA, 35 mM STDC, and 35 mM β-CD. Based on the difference in viscosity between the sample zone and PEO solution and because of the STDC sweeping, the discontinuous system effectively stacked 670 nL of the 9 pairs of FMOC-derivatized amino acid enantiomers without losing chiral resolution. Consequently, the limits of detection for the 9 pairs of FMOC-derivatized amino acid enantiomers were reduced to 40-60 nM. This method was successfully used to determine d-Tryptophan (Trp), l-Trp, d-Phenylalanine (Phe), l-Phe, d-Glutamic acid (Glu), and l-Glu in various types of beers.

Abstract
A chiral capillary electrophoretic method with nearly full pH window was explored for the separation and determination of dl-penicillamine. A facile one-pot labeling technique was coupled in the method for introduction of chromophore and charge groups onto the analytes to facilitate the electromigration and sensitive detection. By using simply a cost-effective neutral β-cyclodextrin as chiral selector, baseline separation of the dl-penicillamine was achieved from pH 2.0 to over pH 10. Quantification of standard d- and l-penicillamines was demonstrated by taking pH 4.5, 7.4, and 9.7 as the representatives of acidic, neutral, and basic conditions. The working curves were constructed between peak area and concentration, having linear ranges of 8.56-8.56 × 10(2) μg/mL for pH 4.5 and 8.56-1.71 × 10(3) μg/mL for pH 7.4 and 9.7, with correlation coefficients all better than 0.999. The limit of detection (S/N = 3) was 2.58 μg/mL in acidic and neutral conditions or 1.41 μg/mL in basic condition. The method was further validated by assaying the commercial penicillamine tablets, applicable to quantification of the effective enantiomer and the trace impurity of l-penicillamine at a content of down to 0.2, 0.6, and 2.0% for pH 9.7, 4.5, and 7.4, respectively. The recovery determined by spiking technique was in a range from 93.1 to 105 %. The method is easily extendable to the analysis of other chiral amines or amino acids.

Abstract
TLC and HPLC methods were developed for indirect chiral separation of penicillamine (3,3-dimethylcysteine) enantiomers after derivatization with Marfey's reagent (FDNP-Ala-NH(2)) and two of its structural variants, FDNP-Phe-NH(2) and FDNP-Val-NH(2). The binary mobile phase of phenol-water (3:1 v/v) and solvent combinations of acetonitrile and triethylamine phosphate buffer were found to give the best separation in normal and reversed-phase TLC, respectively. The diastereomers were also resolved on a reversed-phase C18 HPLC column with gradient elution of acetonitrile and 0.01 m trifluoroacetic acid. The results due to these three reagents were compared. The method was successful for checking the enantiomeric impurity of l-penicillamine in d-penicillamine and to check the enantiomeric purity of pharmaceutical formulations of d-penicillamine. The method was validated for linearity, repeatability, limit of detection and limit of quantification.

Abstract
Due to their identical chemical and physical properties, the separation of enantiomers has been considered one of the most difficult challenges in chemistry from both an analytical or a preparative viewpoint. With the development and commercialization of many new or improved chiral stationary phases and chiral additives, interest in enantiomeric separation by HPLC has grown tremendously in the last two decades. Cyclodextrins and modified cyclodextrins are widely used chiral selectors. They are used as either the chiral stationary phases, as chiral mobile phase additives, or as chiral counter-ions. This review describes the historical development of derivatized and underivatized cyclodextrins in HPLC and their various applications.

Abstract
Investigation of individual drug enantiomers is required in pharmacokinetic and pharmacodynamic studies of drugs with a chiral centre. Cyclodextrins (CDs) are extensively used in high-performance liquid chromatography as stationary phases bonded to a solid support or as mobile phase additives in HPLC and capillary electrophoresis (CE) for the separation of chiral compounds. We describe here the basis for the liquid chromatographic and capillary electrophoretic resolution of drug enantiomers and the factors affecting their enantiomeric separation. This review covers the use of CDs and some of their derivatives in studies of compounds of pharmacological interest.

Abstract
Penicillamine enantiomers derivatized with N-[4-(6-dimethylamino-2-benzofuranyl)phenyl]maleimide (DBPM) were separated and determined by high-performance liquid chromatography. A fluorogenic reagent, DBPM easily reacted with D- or L-penicillamine to give each two kinds of strong fluorescent derivatives (D1-, D2-, L1- and L2-DBPM), which could be separated on a Pirkle-type chiral stationary phase using an eluent of 75% aqueous methanol solution containing 0.15 M CH3COONH4 and 0.05 M tetra-n-butylammonium bromide. Two of the peaks (D1- or L1-DBPM), having a shorter retention time than the others, had almost the same retention times (25 min for D1-DBPM and 25.7 min for L1-DBPM). The retention times of the peaks eluted later were 28 min and 31.6 min for D2- and L2-DBPM respectively. Linear calibration curves over the range of 2-50 pmol per injection were obtained for D- and L-penicillamines with a detection limit of 290 and 350 fmol at respectively at a signal-to-noise ratio of 3. Using the proposed method, the absence of contamination of L-penicillamine in a commercially available D-penicillamine preparation (capsule) was confirmed.

Abstract
Derivatization reactions aimed at creating the basis for the chromatographic resolution of biologically and pharmaceutically important enantiomers are reviewed, with emphasis on the literature published in the last 10 years. Three main aspects of chiral derivatization are discussed. (a) Enantiomers containing suitable functional groups (amino, carboxyl, hydroxyl, epoxy, etc.) are transformed into covalently bonded diastereomeric derivatives using homochiral derivatizing agents. The diastereomers formed (esters, amides, urethanes, urea and thiourea, etc., derivatives) can be separated on achiral stationary phases. The derivatization reactions often afford further advantages, such as the improvement of chromatographic properties and the detectability of the solutes using UV and fluorimetric detectors. (b) Covalent but achiral derivatization is often necessary even with the use of chiral stationary phases enabling in principle direct enantioseparations (Pirkle-type columns, cyclodextrin-bonded phases, glycoprotein column and functionalized cellulose columns). The main goals of these derivatization reactions (which are analogous to those discussed above), are to introduce functional groups into the molecule of the enantiomers that improve the possibilities for chiral interactions or block functional groups to avoid non-specific interactions. (c) In the broader sense, the dynamic formation of diastereomers using chiral mobile phase additives (cyclodextrins, various reagents to form diastereomeric ion pairs, adducts, mixed metal complexes) can also be considered to be chiral derivatization reactions and is therefore briefly discussed also.
