Oxygenated compounds from the bioconversion of isostevic acid and their inhibition of TNF-alpha and COX-2 expressions in LPS-stimulated RAW 264.7 cells
[摘要]:Fourteen oxygenated compounds were isolated from the preparative-scale biotransformation of isostevic acid (ent-beyeran-19-oic acid). Incubation of it with Aspergillus niger BCRC 32720 produced eight metabolites, four with Bacillus megaterium ATCC 14581,
