摘要:
There is provided a method of producing at least one unsaturated amino acid from at least one amino acid comprising at least two carbonyl groups, the method comprising (a) contacting a recombinant microbial cell with a medium comprising the amino acid comprising the carbonyl groups, wherein the cell is genetically modified to comprise -at least a first genetic mutation that increases the expression relative to the wild type cell of an enzyme (E) selected from the CYP152 10 peroxygenase family, and -at least a second genetic mutation that increases the expression relative to the wild type cell of at least one NAD(P)+ oxidoreductase (E2) and the corresponding mediator protein.
摘要:
The present invention relates to biaryl derivatives of Formula 1, a method for preparing the same, a pharmaceutical composition comprising the same and use thereof. The biaryl derivatives of Formula 1 according to the present invention promote GLP-1 formation in the gastrointestinal tract and improve insulin resistance in the liver or in muscle due to anti-inflammatory action in macrophages, lipocytes, etc., and can accordingly be effectively used for preventing or treating diabetes, complications of diabetes, obesity, non-alcoholic fatty liver, steatohepatitis, osteoporosis or inflammation.
