Application of biocatalysis in synthetic chemistry

Author: Brady, D ; Molefe, M ; Steenkamp, Lucia H ; Parkinson, C ; Jordaan, J ; Visser, Daniel F ; Simpson, C ; Chhiba, Varsha P ; Mathiba, K Date: Nov 2006 It was found that the nitrile hydratases in microorganisms isolated from around the world had infra-species amino acid sequence differences, and this provided an explanation for the variability of nitrile substrate usage within the species. ...

Decision making in the development of a biocatalytic route for resolution of S-naproxen: from screening to scale-up

Author: Steenkamp, Lucia H ; Brady, D Date: Jun 2010 The non-steroidal anti-inflammatory drug naproxen is most effective as the single S-naproxen enantiomer. However, typical synthetic routes to naproxen yield the racemate of both the R and the S stereoisomers. Biocatalysts can be used to resolve ... Read more
Naproxen: from skunk work to scale-up

Author: Steenkamp, Lucia H ; Brady, D Date: Nov 2008 The presentation starts with a comparison between Naproxen and Aspirin. The characteristics and properties of Naproxen are explained, as well as the biocatalysis and the screening of the enzyme activity and selectivity. It ends with a discussion ... Read more
Screening of commercial enzymes for the enantioselective hydrolysis of R,S-naproxen ester

Author: Steenkamp, Lucia H ; Brady, D Date: 03 Mar 2003 This study focused on the identification of suitable lipase or esterase activity for enantiomeric resolution of (R, S)-naproxen. For an economically viable reaction the enantiomeric ratio (E) should preferably be >100, while maximising the ... Read more
