Isomeric differentiation and quantification of alpha, beta-amino acid-containing tripeptides by the kinetic method: alkali metal-bound dimeric cluster ions
(Elsevier Science BvAmsterdamHolanda, 2004)
Relevance and bio-catalytic strategies for the kinetic resolution of ketoprofen towards dexketoprofen
(Taylor & Francis, 2017-11-10)
This review presents the most relevant investigations concerning the biocatalytic kinetic resolution of racemic ketoprofen to dexketoprofen for the last 22 years. The advantages related to the administration of the ...
First chemoenzymatic synthesis of organoselenium amines and amides
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
A series of organoselenium amines have been synthesized and submitted to the enzymatic kinetic resolution by acetylation mediated by CAL-B (Novozym 435) to give the corresponding chiral amides in an enantiomerically pure ...
Influence of Water on Enzymatic Esterification of Racemic Ketoprofen with Ethanol in a Solvent-Free System
(Springer/Plenum Publishers, 2019-05)
The effect of water added in the kinetic resolution of rac-ketoprofen with ethanol catalyzed with Candida antarctica lipase B was investigated under reaction conditions and at a molecular level. The reaction was performed ...
Stereoselective analysis of carvedilol in human plasma and urine using HPLC after chiral derivatization
(John Wiley & Sons Ltd, 2008-07-01)
An enantioselective high-performance liquid chromatographic method for the analysis of carvedilol in plasma and urine was developed and validated using (-)-menthyl chloroformate (MCF) as a derivatizing reagent. Chloroform ...
Asymmetric microbial reduction of ketones: absolute configuration of trans-4-ethyl-1-(1S-hydroxyethyl)cyclohexanol
(Pergamon-Elsevier B.V. Ltd, 2009-12-11)
A set of five fungal species, Botrytis cinerea, Trichoderma viride and Eutypa lata, and the endophytic fungi Colletotrichum crassipes and Xylaria sp., was used in screening for microbial biocatalysts to detect monooxygenase ...
