  An insight into the curdione biotransformation pathway by Aspergillus niger

  摘要：

  Curdione (1), a sesquiterpene with a germacrane skeleton from rhizomes of Curcuma wenyujin, has attracted attention due to its important pharmacological properties. Herein, we investigated the chemo-biotransformation of curdione (1) systematically using Aspergillus niger AS 3.739. Regio- and stereoselective hydroxylation of curdione with filamentous fungus A. niger AS 3.739 led to seven metabolites including four new compounds 3-hydroxycurcumalactone, 2-hydroxycurcumalactone, (10S)-9,10-dihydroxy-curcumalactone and (10R)-9,10-dihydroxy-curcumalactone. Their structures were determined by spectroscopic techniques including two-dimensional NMR and TOF-MS (Time of Flight Mass Spectrometry). Based upon the analysis of biological and chemical conversions of curdione, a tentative metabolic pathway via chemo-bio cascade reactions is proposed in A. niger system, which provides an insight into the corresponding metabolism of curdione in animal systems. In addition, experiments with selected monooxygenase inhibitors suggest that cytochrome P450 monooxygenase played a crucial role in the hydroxylation of curdione.

  Five germacrane‐type sesquiterpene alcohols obtained from curdione (1) by microbial biotransformation were isolated. Their structures were characterized as (2R)‐2β‐hydroxycurdione (2), 1α, 10β‐epoxy‐11‐hydroxycurdione (3), (2S)‐2α, 11‐dihydroxycurdione (4), 11,15‐dihydroxycurdione (5) and (3R)‐3α‐hydroxycurdione (6) based on the extensive NMR studies. Among them, 4, 5 and 6 are new compounds. Copyright

• “Mirror-Image” Manipulation of Curdione Stereoisomer Scaffolds by Chemical and Biological Approaches: Development of a Sesquiterpenoid Library

  The sesquiterpenoid curdione is one of the main bioactive components in the essential oil of Rhizoma Curcumae (Curcuma wenyujin, Curcuma phaeocaulis, and Curcuma kwangsiensis), which has been clinically used for the treatment of cancer in mainland China. Recently it was reported that natural curdione could be hydroxylated by Aspergillus niger and transferred to its corresponding curcumalactones under acidic conditions. Based on this study, the development of a sesquiterpenoid library through the "mirror-image" manipulation of bioactive (non)natural curdione scaffolds by chemical and biological approaches is presented herein. A. niger induced the hydroxylation of two pairs of curdione enantiomers, yielding the corresponding mirror-image hydroxylated curdiones. Simultaneously, the acid-mediated intramolecular "ene" rearrangements of these curdiones and hydroxylated curdione enantiomers yielded the corresponding mirror-image curcumalactones and hydroxylated curcumalactones. Among the 16 pairs of enantiomers obtained in this study, 23 compounds are new sesquiterpenoids. These curdione and curcumalactone derivatives are of particular interest, as they have the potential to be used as lead compounds and scaffolds in drug discovery.

  Curdione, a sesquiterpene with a germacrane skeleton, was incubated with suspension cultured cells induced from calli of Lonicera japonica for 10 days. The ethyl acetate-soluble fraction of the culture medium gave a number of products, of which six were shown to be (2S)-2-hydroxycurdione, (2R)-2-hydroxycurdione, (8S)-6-hydroxycurdione, (2R, 8S)-8-hydro-2-hydroxycurdione, (1S, 10S)-1,10-epoxycurdione and (1R, 10R)-1.10-epoxycurdione, respectively.
