Tripterygium wilfordii, tripdiolide, triptolide, diterpene biotransformation, plant cell culture, fungi. Aspergillus fumigatus.


Studies on the biotransformation of several synthetic diterpene analogues with plant cell cultures of Tripterygium wilfordii and the fungus, Aspergillus fumigatus, are described. These enzyme-catalyzed processes allow introduction of oxygen functions (hydroxyl and carbonyl) into rings A and B of the diterpene skeleton to afford novel analogues. An interesting epoxidation reaction is observed in biotransformation with the plant cell culture system. The products obtained bear a close structural relationship to the natural products, tripdiolide and triptolide.
