主 题:Isoangustone A Microbial transformation Mucor hiemalis CGMCC 3.14114 Structural diversity Glycosylation Sulfation
摘 要:Isoangustone A (1) is an isoprenylated flavonoid isolated from licorice. It has been reported to possess anti-microbial, anti-oxidative, anti-inflammatory, and anti-tumor activities. In order to increase its structural diversity, microbial transformation of 1 was conducted by Mucor hiemalis CGMCC 3.14114 to obtain three new compounds. By extensive NMR and MS spectroscopic analyses, their structures were identified as isoangustone A 7-O-glucoside (2), isoangustone A 7-O-glucoside-4'-O-sulfate (3), and isoangustone A 7,3 'di-O-glucoside (4), respectively. The major biotransformation reaction was glycosylation at C-7. Sulfation is rare for microbial transformation.
