Exploiting a Step in Diterpenoid Biosynthesis by the Fungus Fusarium Fujikuroi
The scope of the microbiological transformation of ent-kaurenoid diterpenes by the fungus Fusarium (Gibberella) fujikuroi which utilise the ent-kaurene and ent-kauren-19-oic acid oxidases and the
Biotransformation of Salpichrolides A, C, and G by Three Filamentous Fungi.
Biotransformation of salpichrolide A with Cunninghamella elegans produced stereoselective hydroxylated, oxidized, and reduced derivatives in different positions of the A, B, and C rings and C-5-C-6 epoxide opening.
Biotransformation of agallochaexcoerin A by Aspergillus flavus
This microbial bioconversion was achieved by unusual dehydration at C-4 position and was confirmed by using IR, UV, 1H NMR and HR-ESI-MS techniques.
Biotransformations of diterpenoids and triterpenoids: a review
This article describes the biotransformation products of diterpenoids and triterpenoid in a variety of biological media and places emphasis on reporting the metabolites that may be of special interest as well as the practical aspects of this work in the field of microbial transformations.


Chemical Structures of Excoecarins A, B and C: Three New Labdane-Type Diterpenes from Wood, Excoecaria agallocha.
Three new diterpenes, excoecarins A (2), B (3) and C (4) have been isolated from the wood of Excoecaria agallocha LINN. The structures of excoecarins A, B and C were established as (13R, 14R)-ent-8α,

An enzymic site of inhibition of gibberellin biosynthesis by Amo 1618 and other plant growth retardants.
Evidence shows that an enzymic reaction resulting in the production of (-)-kaurene in a flowering plant system is inhibited in the presence of Amo 1618 or certain other plant growth retardants, which strongly supports the idea that (-)kauren19-ol is an intermediate in gibberellin biosynthesis.
