- Structure, activity, and inhibition of the carboxyltransferase β-Subunit of acetyl coenzyme a carboxylase (AccD6) from mycobacterium tuberculosis
-
In Mycobacterium tuberculosis, the carboxylation of acetyl coenzyme A (acetyl-CoA) to produce malonyl-CoA, a building block in long-chain fatty acid biosynthesis, is catalyzed by two enzymes working sequentially: a biotin carboxylase (AccA) and a carboxyl

- Evaluation of the Edman degradation product of vancomycin bonded to core-shell particles as a new HPLC chiral stationary phase
-
A modified macrocyclic glycopeptide-based chiral stationary phase (CSP), prepared via Edman degradation of vancomycin, was evaluated as a chiral selector for the first time. Its applicability was compared with other macrocyclic glycopeptide-based CSPs: TeicoShell and VancoShell. In addition, another modified macrocyclic glycopeptide-based CSP, NicoShell, was further examined. Initial evaluation was focused on the complementary behavior with these glycopeptides. A screening procedure was used based on previous work for the enantiomeric separation of 50 chiral compounds including amino acids, pesticides, stimulants, and a variety of pharmaceuticals. Fast and efficient chiral separations resulted by using superficially porous (core-shell) particle supports. Overall, the vancomycin Edman degradation product (EDP) resembled TeicoShell with high enantioselectivity for acidic compounds in the polar ionic mode. The simultaneous enantiomeric separation of 5 racemic profens using liquid chromatography-mass spectrometry with EDP was performed in approximately 3?minutes. Other highlights include simultaneous liquid chromatography separations of rac-amphetamine and rac-methamphetamine with VancoShell, rac-pseudoephedrine and rac-ephedrine with NicoShell, and rac-dichlorprop and rac-haloxyfop with TeicoShell.

- Process of producing optically active propionic acid ester derivatives
-
Processes for producing optically active ester derivatives are disclosed. According to the present invention an optically active aryloxyphenoxy propionate derivative is produced by reacting a chlorinated heterocyclic aromatic compound with (2R)-2-(4-hydroxyphenoxy)propionic acid tetrahydrofurfuryl ester in an anhydrous solvent in the presence of a base. According to the present invention, an optically active propionate derivative of the formula [I] STR1 (wherein R represents hydrogen or 3-chloro-5-trifluoromethyl-2-pyridyl group) is produced by reacting a corresponding optically active methyl propionate derivative with tetrahydrofurfuryl alcohol, or by reacting a corresponding optically active propionic acid derivative with tetrahydrofurfuryl alcohol, or by reacting (2S)-tetrahydrofurfuryl 2-chloropropionate with a corresponding phenol derivative in specific conditions.
