Marine diterpene glycosides (MDGs) respresent a small but highly significant group of the much larger class of marine diterpenes. The three well-studied examples of MDGs are eleutherobins, pseudopterosins and fuscosides, all of which exhibit extremely promising biological activity.

Biotransformation of diterpenes and diterpene derivatives by Beauveria bassiana ATCC 7159
Phytochemistry, 2001The biohydroxylation of stemodin and stemodinone by Beauveria bassiana ATCC 7159 gave exclusively 2alpha,13,18-trihydroxystemodane and 13,18-dihydroxystemodan-2-one respectively. Stemarin was converted to the novel 1beta,13,19-trihydroxystemarane and 13-hydroxystemarane-19-carboxylic acid.

The Biosynthesis of the Diterpenes
1971The diterpenes contain a variety of structural types and functional groups which have provided a rich source of biogenetic speculation. Over the last decade biosynthetic evidence has been accumulating to support and modify some of these speculations. It is our purpose to review some of this evidence in this chapter.

Bacterial Diterpene Biosynthesis
Angewandte Chemie International Edition, 2019AbstractThis Minireview summarises recent developments in the biosynthesis of diterpenes by diterpene synthases in bacteria. It is structured by the class of enzyme involved in the first committed step towards diterpenes, starting with type I diterpene synthases, followed by type II enzymes and the more recently discovered UbiA‐related diterpene ...

Mechanistic Characterization of Diterpene Synthase Pairs for Tricyclic Diterpenes from Cyanobacteria
Journal of the American Chemical SocietyIn recent years, genome mining in cyanobacteria has revealed abundant gene clusters related to natural product biosynthesis. However, only a few terpene synthases (TSs) have been identified from this bacterial phylum. Pfam profiles, such as PF03936 and PF19086, which are frequently used for TS retrieval, are built from plant, bacterial, and fungal TSs.

The study of terpenes is intimately connected with the development of organic chemistry. In the early years of terpene research the peculiar structures of this type of compounds posed formidable problems for which methods of attack had to be invented; and the organic chemist of today owes a great deal to the pioneers in this field such as Wallach ...

At least 2500 diterpenes are found in a large number of plant families (Banthorpe and Charlwood, 1980; Croteau and Johnson, 1981; Devon and Scott, 1972; Gershenzon and Croteau, 1991; Hanson, 1991). Most of these compounds fit into about 20 major groups (Fig. 22.1).
