Enzyme-catalysed enantioselective hydrolysis of racemic naproxen nitrile.
نویسندگان
چکیده
The bacterial strain Rhodococcus butanica (ATCC 21197), which exhibits nitrilase and nitrile hydratase/amidase activities, catalyses the enantioselective hydrolysis of racemic naproxen nitrile (R/S)-1 to furnish a moderate enantiomeric excess of (S)-naproxen (S)-3. Racemic naproxen amide (R/S)-2 is not a good substrate for this strain. Resting cells of the newly selected bacterial strain Rhodococcus sp. C3II catalyse the enantioselective hydrolyses of racemic naproxen nitrile (R/S)-1 and naproxen amide (R/S)-2 as well, to give (S)-3 in excellent optical (99% e.e.) and good chemical yields in aqueous medium and in the biphasic system of phosphate buffer/hexane.

Enantioselective hydrolysis of racemic naproxen nitrile and naproxen amide to S-naproxen by new bacterial isolates.
Bacteria were enriched from soil samples with succinate as a carbon source and racemic naproxen nitrile [2-(6-methoxy-2-naphthyl)propionitrile] as sole source of nitrogen. Since naproxen nitrile was only poorly soluble in water media amended with different water-immiscible organic phases were used for the enrichments. With pristane (2,6,10,14-tetramethylpentadecane) as the organic phase two bac...
متن کاملPurification and characterization of nitrilase responsible for the enantioselective hydrolysis from Acinetobacter sp. AK 226.
A nitrilase was purified, apparently to homogeneity, from a cell extract of Acinetobacter sp. AK 226, which converts racemic 2-(4'-isobutylphenyl)propionitrile (Ibu-CN) to S-(+)-2-(4'-isobutyl-phenyl)propionic acid (S-(+)-ibuprofen). The molecular weight of the native enzyme was estimated as 580,000 upon gel filtration. The nitrilase hydrolyzed many kinds of nitrile compounds such as aliphatic,...
متن کاملThe use of enzymes for the catalysis of key reactions in the synthesis of biologically active natural products and analogues
The incorporation of enzyme-catalysed reactions as key features in multi-step organic syntheses is becoming more widespread. Various hydrolase and oxidoreductase enzymes have been used in syntheses of antibiotics and compounds of importance in inflammation and heart disease. The employment of enzymes as catalysts in synthetic organic chemistry is becoming widespread; comprehensive recent review...
متن کاملHydrolysis of ibuprofen nitrile and ibuprofen amide and deracemisation of ibuprofen using Nocardia corallina B-276.
A novel application of whole cells of Nocardia corallina B-276 for the deracemisation of ibuprofen is reported. This microorganism successfully hydrolysed ibuprofen nitrile to ibuprofen amide, and ibuprofen amide to ibuprofen, using a suspension of cells in a potassium phosphate buffer solution (0.1 M, pH = 7.0). These results can be explained by the presence of NHase and amidase enzymes, but t...
متن کاملHighly efficient and enantioselective biotransformations of β-lactam carbonitriles and carboxamides and their synthetic applications.
Catalyzed by Rhodococcus erythropolis AJ270, a nitrile hydratase and amidase containing microbial whole cell catalyst, a number of racemic 1-arylmethyl- and 1-allyl-4-oxoazetidine-2-carbonitriles and carboxamides underwent efficient transformations under very mild conditions to produce enantiopure functionalized S-amide and R-acid products in excellent yields. While the nitrile hydratase showed...
