Microbial transformation of BAVACHIN (cas 19879-32-4) by Absidia coerulea

Add time:09/27/2019    Source:infona.pl

Microbial transformation of BAVACHIN (cas 19879-32-4) (1), one of the major bioactive components of Psoralea corylifolia L., was performed by using Absidia coerulea. Three oxidized metabolites were obtained in the biotransformation of 1, and their structures were elucidated as bavachinone A (2), (2S)-4′-hydroxy-6,7-[(R)-2-(1-hydroxy-1-methylethyl)-2,3-dihydrofurano]flavanone (3), and (2S)-4′,7-dihydroxy-6-(2,3-dihydroxy-3-methylbutyl)flavanone (4) based on the spectroscopic analyses. Among them, metabolites 3 and 4 were new compounds. The biotransformation study suggested that 1 was fully oxidized to its metabolites within 5days. Thus, biotransformation by A. coerulea can be used as a promising method for oxidation of bavachin.
