- Preparation and characterization of a new open-tubular capillary column for enantioseparation by capillary electrochromatography
-
In order to use the enantioseparation capability of cationic cyclodextrin and to combine the advantages of capillary electrochromatography (CEC) with open-tubular (OT) column, in this study, a new OT-CEC, coated with cationic cyclodextrin (1-allylimidazolium-β-cyclodextrin [AI-β-CD]) as chiral stationary phase (CSP), was prepared and applied for enantioseparation. Synthesized AI-β-CD was characterized by infrared (IR) spectrometry and mass spectrometry (MS). The preparation conditions for the AI-β-CD-coated column were optimized with the orthogonal experiment design L9(34). The column prepared was characterized by scanning electron microscopy (SEM) and elemental analysis (EA). The results showed that the thickness of stationary phase in the inner surface of the AI-β-CD-coated columns was about 0.2 to 0.5?μm. The AI-β-CD content in stationary phase based on the EA was approximately 2.77?mmol·m?2. The AI-β-CD-coated columns could separate all 14 chiral compounds (histidine, lysine, arginine, glutamate, aspartic acid, cysteine, serine, valine, isoleucine, phenylalanine, salbutamol, atenolol, ibuprofen, and napropamide) successfully in the study and exhibit excellent reproducibility and stability. We propose that the column, coated with AI-β-CD, has a great potential for enantioseparation in OT-CEC.

- Chromatographic Resolution of α-Amino Acids by (R)-(3,3'-Halogen Substituted-1,1'-binaphthyl)-20-crown-6 Stationary Phase in HPLC
-
Three new chiral stationary phases (CSPs) for high-performance liquid chromatography were prepared from R-(3,3'-halogen substituted-1,1'-binaphthyl)-20-crown-6 (halogen = Cl, Br and I). The experimental results showed that R-(3,3'-dibromo-1,1'-binaphthyl)-20-crown-6 (CSP-1) possesses more prominent enantioselectivity than the two other halogen-substituted crown ether derivatives. All twenty-one α-amino acids have different degrees of separation on R-(3,3'-dibromo-1,1'-binaphthyl)-20-crown-6-based CSP-1 at room temperature. The enantioselectivity of CSP-1 is also better than those of some commercial R-(1,1'-binaphthyl)-20-crown-6 derivatives. Both the separation factors (α) and the resolution (Rs) are better than those of commercial crown ether-based CSPs [CROWNPAK CR(+) from Daicel] under the same conditions for asparagine, threonine, proline, arginine, serine, histidine and valine, which cannot be separated by commercial CR(+). This study proves the commercial usefulness of the R-(3,3'-dibromo-1,1'-binaphthyl)-20-crown-6 chiral stationary phase.

- Chiral separation of underivatized amino acids by reactive extraction with palladium-BINAP complexes
-
(Figure Presented) In answer to the need for a more economic technology for the separation of racemates, a novel system for reactive enantioselective liquid-liquid extraction (ELLE) is introduced. Palladium (S)-BINAP complexes are employed as hosts in the separation of underivatized amino acids. The system shows the highest selectivity for the ELLE of tryptophan with metal complexes as hosts reported to date and shows a good selectivity toward a range of natural and unnatural amino acids. Furthermore, the host can be prepared in situ from commerically available compounds. Bulk-membrane transport in the form of U-tube experiments demonstrates the enantioselective and catalytic nature of the transport. The dependency of the system on parameters such as pH, organic solvent, and host-substrate ratio has been established. 31P NMR spectroscopy has been used to confirm the preferred enantiomer in the extraction experiments. The intrinsic selectivity was deduced by determination of the association constants of the palladium complex with the tryptophan enantiomers.

- Reduction potential of histidine free radicals: A pulse radiolysis study
-
The technique of pulse radiolysis has been used to demonstrate that all histidine free radicals (designated His.+) produced by oxidation of histidine by Br2.- radical anions can oxidise the water soluble vitamin E analogue, Trolox C (k = 1.0 ± 0.2 × 109 dm3 mol-1 s-1 at pH 6.95). It has also been shown that His.+ radicals can react with tryptophan in electron transfer equilibria involving both His.+ and Trp.+ species over the pH range 6.4-9.0. The ΔE values [E(Trp.+/Trp) - E(His.+/His)] range from -140 to -161 mV and indicate an E7(His.+/His) value of 1170 mV [based on E7(Trp.+/Trp) = 1015 mV at pH 7]. The effect of pH on E(His.+/His) was accounted for by assuming that His.+ can deprotonate to yield a bi-allylic free radical, designated His (-H+).. The pKa for this dissociation was estimated to be in the range 5-7. The implications of the relatively high reduction potential for His.+ in its possible participation in the mechanism of action of non-heme metalloenzymes is discussed.

The monoclonal antibody of this invention can be produced such that fused cells between proper cells (e.g., spleen cells prepared from a mammal) immunized with TRF and other proper cells (e.g., mouse myeloma cells) having large proliferation potential are cloned, and the fused cells are cultivated in vivo or in vitro. The monoclonal antibody of this invention is effective as an immunoadsorbent for the TRF or an inhibitor of the TRF-activity.

- Amino-acid composition, method for its production and medical composition containing it
-
An amino acid composition comprising a specified amino acid sequence, showing a molecualr weight of 16,000 to 20,000 daltons upon SDS-polyacrylamide gel electrophoresis and 30,000 to 45,000 daltons upon gel filtration, and showing a specific activity of 0.5 x 109 to 3 x 109 units/mg protein. The amino acid composition exhibits an anti-tumor activity without injuring normal cells. A process of producing the amino acid composition via gene recombination technique and medical compositions thereof are also disclosed.
